Aironet to Cable Modem [7:38212]
First off I am not familiar with the aironet line! I have a cable modem (dynamic ip address) connected to a Aironet 350 AP (AIR-AP352E2C). I am able to get the aironet dynamic ip assigned to the ethernet interface (from the cable company dhcp servers). I was able to assign a static ip to the AP radio interface and connect via my wireless nic (static ip). But, I cannot access the internet via the cable modem. My guess is that it is more of a switch then a router. I was hopeful it had a little bit of routing capabilities. I assume that because the ethernet int and AP radio int are on different subnets that is the reason I can't talk. But, again I am not sure and hope someone can help me out!!! I would like any advice to get this working without any other equipment. I was hoping to do this without using one of my routers! Also, is there any way to configure it as a DHCP server? And any config advice would be helpful!!! Thanks for any advice you may give me !

Re: Etherchannel/ISL trunk failure [7:38085]
Kelly great post and I do appreciate the help, I no think my englesh was that bad (just kidding), been living in Europe too long obviously. Back to the problem anyway, I removed the ISL trunk from the etherchannel and it's all OK now, no errors for the past couple of days. Problem is it's at an exhibition so it's fairly important it doesn't go down. The reasoning behind the ISL trunk was an application that couldn't handle an address with any zeros, so we needed an extra VLAN. The network requirements have a habit of changing rapidly too so it made sense to implement it at the time. My skill level? hmm not sure either, but you're right keep it simple works best for me too. cheers Pat -- email me on : [EMAIL PROTECTED] Kelly Cobean wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I'll make you a deal...I won't pose design questions in response to your fault questions when you can criticize me for trying to help you using something other than one big, fragmented run-on sentence. Worse than my unsolicited design suggestions are the inability of most people to form a coherent thought in writing to convey their point. It makes it difficult, if not impossible to HELP with the problem at hand when you must focus so hard on deciphering the broken sentence that you can't focus on the technology. Now, I certainly get your point that I'm not sticking strictly to the question at hand, but one of the best design philosophies (which determines in part your troubleshooting methodologies) out there is Keep It Simple. There is no need to apply a technology if it's not going to be used. I suggest this merely because I don't know you, your skill level, or your future plans for this network. My suggesting that you not use ISL if there are no plans for it in the future was an attempt to save you the heart-ache of chasing down a problem that needn't exist, however educational the answer may be. I also caveated my statement with unless you are preparing for multiple VLAN's down the road, so be as scalable as you want, just don't assume that I know your future plans. I'm merely analyzing the problem in front of me. After all, you did say that you had to get this up very quickly. Also note that I DID included some other thoughts for you to check on if diagnosing the problem to resolution is the path you're on, so my message wasn't entirely wasted on babbling about my perceived over-engineering of your network. As with all lists, responses to questions are take it or leave it. If you don't like mine that's fine, but maybe someone else on the list was able to benefit from it.

It's a very simple network with these two switches, a PIX and only VLAN 1 is used. The problem occurred when clients DNS requests failed. The DNS is an NT server which was connected to Switch B, the PIX was connected to Switch A and the default gateway for VLAN 1 was on Switch A. From a PC on Switch A you could ping the NT server and the default gateway and PIX etc, but the NT server couldn't ping the default gateway. Moving a PC to Switch B replicated the problem, I could ping everything else on the network but not the default gateway.

RE: Default Weight in BGP [7:38191]
Actually the value is from 0 to 65535, but this does bring up a questionIf weight is used internally on a router to prefer one egress path over another, and the attribute is never advertised to it's peers, then why would Cisco say the following about the Weight attribute: The administrative weight is local to the router. A weight can be a number from 0 to 65535. Any path that a Cisco router originates will have a default weight of 32768; other paths have weight 0 I guess I'm confused about this statement. If it's an internal-only value, then how would a Cisco router ever use a value of 0?

RE: Stacking 3548s [7:38208]
Cisco Switch Clustering Breakthrough Cisco Switch Clustering technology enables up to 16 interconnected Catalyst 3500 XL, Catalyst 2900 XL, and Catalyst 1900 switches, regardless of geographic proximity, to form a single IP management domain. Cisco Switch Clustering supports a broad range of standards-based connectivity options and configurations to deliver levels of performance that are scalable to meet customer requirements. Switch Cluster connectivity options for the Catalyst 3500 Series XL include Ethernet, Fast Ethernet, Fast EtherChannel, low-cost Cisco GigaStack GBIC, Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because the technology is not limited by proprietary stacking modules or stacking cables, Cisco Switch Clustering expands the traditional stacking domain beyond a single wiring closet and lets users mix and match interconnections to meet specific management, performance, and cost requirements. Catalyst 3500 XL switches can be configured either as command or member switches in a Cisco switch stack or cluster. The command switch serves as the single IP address management point and disburses all management instructions dictated by the network administrator. Command switches can cluster up to 15 additional interconnected member switches regardless of interconnection media.

The foundation exam is almost similiar to the individual exams except that the pressure is greater... I took the foundation exam and while it certainly is a faster way of clearing the certification, I don't really enjoyed the experience. Too stressful. The paper is divided into three sections which will typically have 50 to 60 questions each. And you would need to pass all three sections before you are considered to have passed the paper. This would also mean that as there are less questions in each section, each question will carry a bigger weightage.

RE: Hex to Decimal for the RD [7:38223]
the place values for base 16 numbering starting from right to left are 16^0, 16^1,16^2,16^3, etc. In case your wondering 16^1 means 16 to the power of 1, or just 16. Like wise 16^3 = 16 * 16 * 16. So if you hex value is 2f2, starting with the right most 2, (16^0 * 2)+ (16^1 * 15) + (16^2 * 2). Which breaks down to 2+240+512= 754 in base 10. Also hex digits are 0-9, A=10, B=11,C=12,D=13,E=14,F=15. Hope this helps if you still need clarification let me know, I just took a hudge math coarse last semester and this stuff is still floating around in my head.

RE: Hex to Decimal for the RD [7:38223]
Hex is based on 16, where Dec is based on 10. When you see a value, no matter if it's in dec, hex, bin, or something else, think of each number as being number 0 (the right one), 1, 2, 3, and so on. If you for instance have the decimal value 579: Number 0 would be 9 Number 1 would be 7 Number 2 would be 5 When you have decimal, the system is based on 10, so you will have to use 10 to calculate your way to a result. The number 579 can be calculated this way: 9 * 10^0 = 9 + 7 * 10^1 = 70 + 5 * 10^2 = 500 = Result = 579 This seems pretty silly to calculate a value like that, but that's because we're used to see the value in a 10-based format. Okay, let's take your first 16-based (hex) value - F00. Again, from right to left: Number 0 is 0 Number 1 is 0 Number 2 is F (15 in decimal) Instead of using the number 10 to calculate, you will need to use the number 16 to calculate: The value F00 in hex can be calculated this way: 0 * 16^0 =0 + 0 * 16^1 =0 + F * 16^2 = 3840 = Result = 3840 You can with hex make words if that helps you remember the value, as long as you do not use letters above F. For instance, the value ABBA would be a good one to use for a Swedish Ericsson Server (if they exist), and the value would be calculated like this: A * 16^0 =10 + B * 16^1 = 176 + B * 16^2 = 2816 + A * 16^3 = 40960 = Result = 43962 If this is still a little confusing, the let's continue with your second value, and break it up a little more: 2F2 First number is 2 (2 decimal) which must be multiplied by 16^0 (1). The result is 2. Second number is F (15 decimal) which must be multiplied by 16^1 (16). The result is 240. The third number is 2 (2 decimal) which must be multiplied by 16^2 (256). The result is 512. The final result will therefore give us 2+240+512 = 754 decimal. Conversions between all systems other than decimal is much easier, because they are based on what I call double up. If you start with binary. Binary is based on 2. When you double up, you will get 4. Next time you will get 8. 8 is the number that Octal is based on, but that's not used much anymore. Next time you will get 16. 16 is the number that Hex is based on. Now, you can see that going from hex to binary will be easier. Hex numbers goes from 0 to 15, and binary goes from 0 to 1. So that means that four binary numbers matches one hex number. An example: The hex number F00 again. If you take each number and convert it to binary, it is much easier. 0 = 0 = F = Result = You can now convert the binary number to octal, which is based on three binary numbers instead of four. First, put spaces in between every third to make it easier: 111 100 000 000 You can see that it is the same binary number as above, but it looks different now. Now convert to Octal: 000 = 0 000 = 0 100 = 4 111 = 7 Octal result = 7400 Some people prefer to use binary when converting from hex to decimal. Again, let's take the F00. From Hex to Bin: F 0 0 = Let's split the binary numbers up: 0 * 2^0 (1) = 0 0 * 2^1 (2) = 0 0 * 2^2 (4) = 0 0 * 2^3 (8) = 0 0 * 2^4 (16)= 0 0 * 2^5 (32)= 0 0 * 2^6 (64)= 0 0 * 2^7 (128) = 0 1 * 2^8 (256) = 256 1 * 2^9 (512) = 512 1 * 2^10 (1024) = 1024 1 * 2^11 (2048) = 2048 RESULT = 3840 If you look at the first calculation we did in the beginning, you can see that I came to the same result.

RE: Hex to Decimal for the RD [7:38223]
Bill, Hex is equivalent to Base16 numbering. Decimal is really Base10 numbering. Let's look at an example of Base10 numbering broken down into it's components, then we'll tackle your examples.. The decimal number 4243 drawn out in Base10 is as follows: (4x10^3) + (2x10^2) + (4x10^1) + (3x10^0) ... Let's do the math... 4x1000 + 2x100 + 4x10 + 3x1 = 4243 Simple, right? So hex is exactly the same, except you use powers of 16 and the letters A-F map to numbers 10-15 respectively. Let's do your examples... F00: Fx16^2 + 0x16^1 + 0x16^0 ...Let's do the math... 15x256 + 0x16 + 0x1 = 3840 ...Voila! Youve just converted Hex to decimal. Now how does that give us the Ring/Bridge #'s?...First, you need to understand that the Route Descriptor is broken down like this: , where R=Ring# and B=Bridge# Given that FOO in Binary is only 12 bits but the field above is 16 bits, we have to pad the left side with 0's so as not to change the value (Though it's not displayed this way.) This makes it 0x0F00. In binary, this is: 0x0F00 = This means that the Ring is and the Bridge is when you break the fields apart. Convert this binary back to decimal, you get Ring#=3840, Bridge#=0, (The bridge bits set to all 0's means the ring local to the destination). Valid bridge #'s are 1-15. Your second example: 2F2 = 0x02F2 = 00100010 = Ring 0010 / Bridge 0010 = Ring# 47/Bridge# 2 If you had a RIF that read 0810.02F2.0F00, then the RIF would translate to this: 0810(Routing control bits).Ring47/Bridge2.Ring3840/Bridge0(or ring local to destination) Hope this helps.

RE: Question on PIX 501 [7:38246]
Hi Justin, When you ping, you use the ICMP protocol. When A pings B, A sends ICMP echo-request (number 8) to B, and B sends ICMP echo-reply (number 0) back to A. The PIX does not allow ICMP traffic to come from the outside to the inside, so to change that, you will need to open up for ICMP number 0 (echo-reply). The command for that is: conduit permit icmp any any 0 This is a good way to do it, because then you allow outside devices to reply to your request, but they are not allowed to do a PING themself. If you want PING to work both ways, simply use this command: conduit permit icmp any any Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

Re: Hex to Decimal for the RD [7:38223]
Nice going, Ole! Now, how about an easy way to convert decimal to hex without going through binary (the way I learned)? :) Persio - Original Message - From: Ole Drews Jensen To: Sent: Thursday, March 14, 2002 12:07 PM Subject: RE: Hex to Decimal for the RD [7:38223] Hex is based on 16, where Dec is based on 10. When you see a value, no matter if it's in dec, hex, bin, or something else, think of each number as being number 0 (the right one), 1, 2, 3, and so on. If you for instance have the decimal value 579: Number 0 would be 9 Number 1 would be 7 Number 2 would be 5 When you have decimal, the system is based on 10, so you will have to use 10 to calculate your way to a result. The number 579 can be calculated this way: 9 * 10^0 = 9 + 7 * 10^1 = 70 + 5 * 10^2 = 500 = Result = 579 This seems pretty silly to calculate a value like that, but that's because we're used to see the value in a 10-based format. Okay, let's take your first 16-based (hex) value - F00. Again, from right to left: Number 0 is 0 Number 1 is 0 Number 2 is F (15 in decimal) Instead of using the number 10 to calculate, you will need to use the number 16 to calculate: The value F00 in hex can be calculated this way: 0 * 16^0 =0 + 0 * 16^1 =0 + F * 16^2 = 3840 = Result = 3840 You can with hex make words if that helps you remember the value, as long as you do not use letters above F. For instance, the value ABBA would be a good one to use for a Swedish Ericsson Server (if they exist), and the value would be calculated like this: A * 16^0 =10 + B * 16^1 = 176 + B * 16^2 = 2816 + A * 16^3 = 40960 = Result = 43962 If this is still a little confusing, the let's continue with your second value, and break it up a little more: 2F2 First number is 2 (2 decimal) which must be multiplied by 16^0 (1). The result is 2. Second number is F (15 decimal) which must be multiplied by 16^1 (16). The result is 240. The third number is 2 (2 decimal) which must be multiplied by 16^2 (256). The result is 512. The final result will therefore give us 2+240+512 = 754 decimal. Conversions between all systems other than decimal is much easier, because they are based on what I call double up. If you start with binary. Binary is based on 2. When you double up, you will get 4. Next time you will get 8. 8 is the number that Octal is based on, but that's not used much anymore. Next time you will get 16. 16 is the number that Hex is based on. Now, you can see that going from hex to binary will be easier. Hex numbers goes from 0 to 15, and binary goes from 0 to 1. So that means that four binary numbers matches one hex number. An example: The hex number F00 again. If you take each number and convert it to binary, it is much easier. 0 = 0 = F = Result = You can now convert the binary number to octal, which is based on three binary numbers instead of four. First, put spaces in between every third to make it easier: 111 100 000 000 You can see that it is the same binary number as above, but it looks different now. Now convert to Octal: 000 = 0 000 = 0 100 = 4 111 = 7 Octal result = 7400 Some people prefer to use binary when converting from hex to decimal. Again, let's take the F00. From Hex to Bin: F 0 0 = Let's split the binary numbers up: 0 * 2^0 (1) = 0 0 * 2^1 (2) = 0 0 * 2^2 (4) = 0 0 * 2^3 (8) = 0 0 * 2^4 (16) = 0 0 * 2^5 (32) = 0 0 * 2^6 (64) = 0 0 * 2^7 (128) = 0 1 * 2^8 (256) = 256 1 * 2^9 (512) = 512 1 * 2^10 (1024) = 1024 1 * 2^11 (2048) = 2048 RESULT = 3840 If you look at the first calculation we did in the beginning, you can see that I came to the same result.

CCNP exams-The Truth [7:38249]
a big passage below...i hope some of it makes sense to you ccnp exams are easy. they should be made more difficult in the new 641 series to regain some of their merit. But hey can you guys give me one good reason why cisco would like to have less certified people in the market rather than more? there might be a couple of minor reasons but cisco has drawn up its plans for the future.Once a cert.loses its lust, they would come up with another. they keep getting hefty fees for the exams, they keep getting richer, they keep expanding their non-core business revenue streams, they pay tax, and america's economy revives. guys this would never die out. Certs are here to stay according to me...just the same way as windows is. its all part of a capitalist economy. some foolish people on the boards value the ccnp at its face value. I pity them. If you have 6months of internetworking exp.behind your back , you are ready for the ccnp. I got 6months. Its been 19 days since my first ccnp exam, and im giving CIT in 3. that makes it 22 for the entire ccnp track. I passed wonderfully, always very close to the 900's. my support? well obviously just the book and boson the great. Now i dont want to give wrong ideas to those pursuing the ccnp. Please do it your own way- try to understand everything- i did and then only step onto helpers just as boson if you wish. And if you want to feel prouder after passing the exams,dont use the bosons. Actually the bosons do help more on the ccna than the ccnp. Ive hardly come across questions similar on the real paper in my ccnp track. The boson's just help me feel confident enough to go for the exams. I would also very strongly advise the cramsessions 2-3 hours before the exam. why am i taking this cert and making cisco rich? coz thats the only option i have to get a good enough job. I cant impress anybody with my exp. so i have to hope to be lucky to find a not-so-clever hiring manager who would choose me over the really experienced types coz i have these 4 dumb characters behind my name. And hey anywayz a lot of candidates have a wrong notion of an interview. An interview isint enough to get to know what a candidate is capable of technically. A lot of times, it all boils down to how u get along with the interviewer. well to end my thread, i would like to also mention that the ccie written is no big deal either. Just like guys in here are doubtful of the ccnp's merit nowadays, they would for the ccie in the same way within 6 months. i would take about 10 days of good study and 1 boson day after that to get through the current ccie-written. And finally, i would like to respect the experienced people out there if. You guys are the cool people who probably the ccnp cert were meant for but are being pursued by more or less newbies like me. But we are all humans, we all live in a capitalist economy and we all want to make money and we all dont want it to take too long. now, who wouldnt agree on that?

Re: Loopback Interfaces... [7:37933]
Mark, It sounds like you want to create a huge subnet that spans across 3 links? If you are trying to have both the ethernet interface and the serial interface be unnumbered to the loopback interface you would inherintly introduce a problem to the router. The problem would be with the internal logic of a router running IP (if in fact it is routing). Let's take this scenario as an example. You are the router and you receive a packet destined for 192.168.10.5 which interface do you shoot it out of if the serial interface is addressed 192.168.10.1 255.255.255.0 and the ethernet interface is addressed 192.168.10.1 255.255.255.0, and you don't have any more specific static routes? You are now telling the router the 192.168.10.0/24 subnet is over here, and also saying the 192.168.10.0/24 subnet is over here. I don't see the reasoning in why you would want to try something like this, especially when you are using private addresses. Why not address the ethernet interface seperately and then possibly use the unnumbered loopback 0 on the serial interface? If you want everything to be on the same subnet you could just bridge everything. I am quite familiar with IP, but not such an old head to know all of the inner workings of DECnet. The DECnet concept of basically using a node address instead of addressing each interface kindof goes along with this type of setup you are trying by kindof establishing the loopback interface as the node address. IP was designed to have each interface addressed. In IP as I'm sure you know the mask portion of an IP address defines which hosts reside on this link. By default in your setup there will be 2 connected routes pointing packets destined for the 192.168.10.0/24 subnet to the serial and the ethernet interfaces. If you add more specific routes to it would fix that issue of not knowing which interface to push packets out of since those routes would be more preferred, but I believe these more specific routes would have to be manually entered, because a routing protocol will simply advertise the addressed networks (RIP, IGRP) or subnets (EIGRP, IS-IS, OSPF, BGP), not specific host routes. Crazy idea, Good luck with it and please let us know how it works out for you. Brian Mark Odette II wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... OK, I'll make the question simpler. Can you use a loopback interface in the same respect that you would use an ethernet interface? Create the loopback: Interface Loopback0 Assign it an IP with a /24 mask : ip address 192.168.10.1 Configure the subnet assigned to the loopback interface to a routing process, such as EIGRP or RIP. Assign many other hosts on a LAN or a WAN an IP address that is in the same subnet as the loopback interface. Replicate the above configuration on Router at other end of FR network. add subnet assigned to far-end routers' loopback interface to local EIGRP AS, or RIP; do the same on the far-end routers' config for the same EIGRP AS or RIP configuration. And then, configure FR Subinterface with IP Unnumbered Loopback0, and route traffic across the FR network, with the traffic orininating from either the Router, or another host (if configuration above is legal) on the subnet that is assigned to the Loopback interface. What I want to do, is configure a VoIP enabled router with a loopback interface assigned to 192.168.10.1, and several LAN hosts with the same subnet assignment, i.e., 192.168.10.2, .3, .4, etc., and a /24 subnet mask for all hosts including loopback interface. I then want to create and assign IP Unnumbered loopbackX to a FR P-to-P subinterface. Create EIGRP AS to route Subnets assigned to loopback interfaces on each respective router. Mirror image this configuration on the other end of the wire (FR Network). Configure Dial-Peers with VOIP destinations pointing to the loopback interface of the peer router (other end of the FR Network). Is this Possible?? The reason why I want to use Loopback interfaces, is because I plan to assign a separate subnet to the FastEthernet Interface, and don't believe that the use of the Secondary command will work, i.e., you can't specify IP Unnumbered FastEthernet0 and have the Secondary IP address used ip unnumbered fastethernet0 will use the FastEthernets' Primary address, which is not desired. The Primary Subnet assigned to the FastEthernet Interface will be NAT Translating with a PIX FW (PIX will be doing the NAT) to hit the Internet. For Topology description: Router HQ connects to internet on one subinterface, while connecting to 3 remote offices on a private FR network on a second subinterface. Router Remote1 Will be connecting to the internet on one subinterface, while connecting back to HQ on separate FR subinterface for VoIP over FR traffic only (no Data traffic) Router Remote2 will be doing the same as Remote1 Router Remote3 will also be doing the same as Remote1 ... So much for a simpler

Re: Hex to Decimal for the RD [7:38223]
All very good but an easier route is to configure the ring numbers in hex; the router will give the decimal equivalents. int tok 0 ring 16 source-bridge 0xf00 2 0x2f2 will appear as int tok 0 ring 16 source-bridge 3840 2 754 Fred. Kelly Cobean wrote: Bill, Hex is equivalent to Base16 numbering. Decimal is really Base10 numbering. Let's look at an example of Base10 numbering broken down into it's components, then we'll tackle your examples.. The decimal number 4243 drawn out in Base10 is as follows: (4x10^3) + (2x10^2) + (4x10^1) + (3x10^0) ... Let's do the math... 4x1000 + 2x100 + 4x10 + 3x1 = 4243 Simple, right? So hex is exactly the same, except you use powers of 16 and the letters A-F map to numbers 10-15 respectively. Let's do your examples... F00: Fx16^2 + 0x16^1 + 0x16^0 ...Let's do the math... 15x256 + 0x16 + 0x1 = 3840 ...Voila! Youve just converted Hex to decimal. Now how does that give us the Ring/Bridge #'s?...First, you need to understand that the Route Descriptor is broken down like this: , where R=Ring# and B=Bridge# Given that FOO in Binary is only 12 bits but the field above is 16 bits, we have to pad the left side with 0's so as not to change the value (Though it's not displayed this way.) This makes it 0x0F00. In binary, this is: 0x0F00 = This means that the Ring is and the Bridge is when you break the fields apart. Convert this binary back to decimal, you get Ring#=3840, Bridge#=0, (The bridge bits set to all 0's means the ring local to the destination). Valid bridge #'s are 1-15. Your second example: 2F2 = 0x02F2 = 00100010 = Ring 0010 / Bridge 0010 = Ring# 47/Bridge# 2 If you had a RIF that read 0810.02F2.0F00, then the RIF would translate to this: 0810(Routing control bits).Ring47/Bridge2.Ring3840/Bridge0(or ring local to destination) Hope this helps.

RE: Hex to Decimal for the RD [7:38223]
Thanks, Now you have to remember the DIV and MOD calculation you learned in school. First, learn the values of each of the hex numbers. If we take a max of four hex numbers (1 word, 2 bytes, 16 bits, etc.) you have the following: 16^3 16^2 16^1 16^0 Doing a fast calculation gives us: 4096 256 16 1 That means that 1000 hex is 4096 dec. Got that? - Good! With four numbers, you will have the range of to or 0 to 65535. So if you have the decimal number 5000, you do the following: Step 1: How many times does 4096 fit into 5000? Answer = 1 Step 2: What's left? Answer = 904 Step 3: How many times does 256 fit into 904? Answer = 3 Step 4: What's left? Answer = 136 Step 5: How many times does 16 fit into 136? Answer = 8 Step 6: What's left? Answer = 8 RESULT = 1388 hex is the same as 5000 dec. Here's a practice story for you :-) The 2750 with the 2989 64206 got a 3053 at the old 51966 where 43962 used to 190.

Now, how about an easy way to convert decimal to hex without going through binary (the way I learned)? :) Persio - Original Message - From: Ole Drews Jensen To: Sent: Thursday, March 14, 2002 12:07 PM Subject: RE: Hex to Decimal for the RD [7:38223] Hex is based on 16, where Dec is based on 10. When you see a value, no matter if it's in dec, hex, bin, or something else, think of each number as being number 0 (the right one), 1, 2, 3, and so on. If you for instance have the decimal value 579: Number 0 would be 9 Number 1 would be 7 Number 2 would be 5 When you have decimal, the system is based on 10, so you will have to use 10 to calculate your way to a result. The number 579 can be calculated this way: 9 * 10^0 = 9 + 7 * 10^1 = 70 + 5 * 10^2 = 500 = Result = 579 This seems pretty silly to calculate a value like that, but that's because we're used to see the value in a 10-based format. Okay, let's take your first 16-based (hex) value - F00. Again, from right to left: Number 0 is 0 Number 1 is 0 Number 2 is F (15 in decimal) Instead of using the number 10 to calculate, you will need to use the number 16 to calculate: The value F00 in hex can be calculated this way: 0 * 16^0 =0 + 0 * 16^1 =0 + F * 16^2 = 3840 = Result = 3840 You can with hex make words if that helps you remember the value, as long as you do not use letters above F. For instance, the value ABBA would be a good one to use for a Swedish Ericsson Server (if they exist), and the value would be calculated like this: A * 16^0 =10 + B * 16^1 = 176 + B * 16^2 = 2816 + A * 16^3 = 40960 = Result = 43962 If this is still a little confusing, the let's continue with your second value, and break it up a little more: 2F2 First number is 2 (2 decimal) which must be multiplied by 16^0 (1). The result is 2. Second number is F (15 decimal) which must be multiplied by 16^1 (16). The result is 240. The third number is 2 (2 decimal) which must be multiplied by 16^2 (256). The result is 512. The final result will therefore give us 2+240+512 = 754 decimal. Conversions between all systems other than decimal is much easier, because they are based on what I call double up. If you start with binary. Binary is based on 2. When you double up, you will get 4. Next time you will get 8. 8 is the number that Octal is based on, but that's not used much anymore. Next time you will get 16. 16 is the number that Hex is based on. Now, you can see that going from hex to binary will be easier. Hex numbers goes from 0 to 15, and binary goes from 0 to 1. So that means that four binary numbers matches one hex number. An example: The hex number F00 again. If you take each number and convert it to binary, it is much easier. 0 = 0 = F = Result = You can now convert the binary number to octal, which is based on three binary numbers instead of four. First, put spaces in between every third to make it easier: 111 100 000 000 You can see that it is the same binary number as above, but it looks different now. Now convert to Octal: 000 = 0 000 = 0 100 = 4 111 = 7 Octal result = 7400 Some people prefer to use binary when converting from hex to decimal. Again, let's take the F00. From Hex to Bin: F 0 0 = Let's split the
RE: Question on PIX 501 [7:38246]
Mark, My original question that I sent to the group somehow got lost. Ole was kind enough to respond to a direct query regarding to some fun I am having with installing a Pix (501) for the first time. My firewall background is SonicWall and Watchguard, both are very simple in configuration and work directly out of the box. I was under the impression it was pretty much plug and play, so I decided to test it by putting it between my PC and the rest of the LAN. However, after the initial setup, the Pix passed no information through it. So I went to a ping to start the troubleshooting. The curious (to me) issue was that from the console or the PDM of the Pix I can ping network addresses on both sides of the Pix. From the inside of the Pix, I cannot ping (or browse the web) through the Pix. I cannot even ping the outside interface of the Pix from the inside interface. The specific question is this ... is additional configuration of the Pix required to permit access from the inside interface to the outside interface and beyond? To expand on the topic you and Ole are discussing, is the use of the conduits (or access-lists) required for each and every type of service I want to send from the inside to the outside? I have no problem researching the commands to learn how it is done, I just want to make certain I am on the right path.

FW: MUX Vs Router [7:38258]
In my experience if you have a choice - stay away from the muxes. We had 30 locations with NRS telco lines and muxes with multiple resets being required each week. Since, we have moved to 100% routers on Frame lines. Down time is less than 1% of what it was with the Muxes. We also have much more control over the communication and with IP addressing on the routers, we can monitor with WhatsUp and other software. The Frame circuits are a bit more expensive per month, but the benefits far outweigh the disadvantages. You also have to have one mux on each end of your circuit, no spoke/hub connectivity. By the way, if you decide to use muxes, we have many 8/16/32 port Multitech muxes. Contact me off the group and we can work out a good deal.

Assign many other hosts on a LAN or a WAN an IP address that is in the same subnet as the loopback interface. Replicate the above configuration on Router at other end of FR network. add subnet assigned to far-end routers' loopback interface to local EIGRP AS, or RIP; do the same on the far-end routers' config for the same EIGRP AS or RIP configuration. And then, configure FR Subinterface with IP Unnumbered Loopback0, and route traffic across the FR network, with the traffic orininating from either the Router, or another host (if configuration above is legal) on the subnet that is assigned to the Loopback interface. What I want to do, is configure a VoIP enabled router with a loopback interface assigned to 192.168.10.1, and several LAN hosts with the same subnet assignment, i.e., 192.168.10.2, .3, .4, etc., and a /24 subnet mask for all hosts including loopback interface. I then want to create and assign IP Unnumbered loopbackX to a FR P-to-P subinterface. Create EIGRP AS to route Subnets assigned to loopback interfaces on each respective router. Mirror image this configuration on the other end of the wire (FR Network). Configure Dial-Peers with VOIP destinations pointing to the loopback interface of the peer router (other end of the FR Network). Is this Possible?? The reason why I want to use Loopback interfaces, is because I plan to assign a separate subnet to the FastEthernet Interface, and don't believe that the use of the Secondary command will work, i.e., you can't specify IP Unnumbered FastEthernet0 and have the Secondary IP address used ip unnumbered fastethernet0 will use the FastEthernets' Primary address, which is not desired. The Primary Subnet assigned to the FastEthernet Interface will be NAT Translating with a PIX FW (PIX will be doing the NAT) to hit the Internet.

Brian Lodwick wrote: This has got to be the most confusing message I have ever read. A loopback interface is just a virtual interface. It's not a real interface it's just a virtual interface you can create within the router, and you can create as many as you want. The biggest reason someone would want to use a loopback interface would be for resiliency. If you build a certain session to the loopback interface (BGP, DLSW...) and you have more than one path to reach this router the session will not die if a certain interface dies. ___ ( ) --- r1 Brian Mark Odette II wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

RE: Default Weight in BGP [7:38191]
Weight, like all BGP attributes, is present for EVERY route in the BGP table. So, if the route is sourced from another router, it will need to be assigned a weight. The assigned weight will be 0. (Weight has local-significance only, and is not transited) So, routes sourced locally will have a local weight of 32k. Routes sourced remotely will have a weight of 0. Using route-maps, you can adjust these weights if needed. As to why it's 32k, I assume it has something to do with the fact that the BGP table is de-coupled from the routing table, and ensuring that routers advertize themselves as the best-path as oposed to chosing another BGP route as best. However, this is off the top of my head, I'm sure Halabi or Doyle would have more on this in their books. --Wes Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=38274t=38191 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Hex to Decimal for the RD [7:38223]
Thats easy, just integer divide the decimal number by 16 and put the remainder in the first column. Keep dividing by 16 and placing the remainder in the next column moving right to left until you have a number less than 16 and place it in the left-most column. For example: 873 = 0x369 873/16=54, r9 54/16= 3, r6 3/16= 0, r3 HTH, Prof. Tom Lisa, CCAI Community College of Southern Nevada Cisco ATC/Regional Networking Academy Persio Pucci wrote: Nice going, Ole! Now, how about an easy way to convert decimal to hex without going through binary (the way I learned)? :) Persio - Original Message - From: Ole Drews Jensen To: Sent: Thursday, March 14, 2002 12:07 PM Subject: RE: Hex to Decimal for the RD [7:38223] Hex is based on 16, where Dec is based on 10. When you see a value, no matter if it's in dec, hex, bin, or something else, think of each number as being number 0 (the right one), 1, 2, 3, and so on. If you for instance have the decimal value 579: Number 0 would be 9 Number 1 would be 7 Number 2 would be 5 When you have decimal, the system is based on 10, so you will have to use 10 to calculate your way to a result. The number 579 can be calculated this way: 9 * 10^0 = 9 + 7 * 10^1 = 70 + 5 * 10^2 = 500 = Result = 579 This seems pretty silly to calculate a value like that, but that's because we're used to see the value in a 10-based format. Okay, let's take your first 16-based (hex) value - F00. Again, from right to left: Number 0 is 0 Number 1 is 0 Number 2 is F (15 in decimal) Instead of using the number 10 to calculate, you will need to use the number 16 to calculate: The value F00 in hex can be calculated this way: 0 * 16^0 =0 + 0 * 16^1 =0 + F * 16^2 = 3840 = Result = 3840 You can with hex make words if that helps you remember the value, as long as you do not use letters above F. For instance, the value ABBA would be a good one to use for a Swedish Ericsson Server (if they exist), and the value would be calculated like this: A * 16^0 =10 + B * 16^1 = 176 + B * 16^2 = 2816 + A * 16^3 = 40960 = Result = 43962 If this is still a little confusing, the let's continue with your second value, and break it up a little more: 2F2 First number is 2 (2 decimal) which must be multiplied by 16^0 (1). The result is 2. Second number is F (15 decimal) which must be multiplied by 16^1 (16). The result is 240. The third number is 2 (2 decimal) which must be multiplied by 16^2 (256). The result is 512. The final result will therefore give us 2+240+512 = 754 decimal. Conversions between all systems other than decimal is much easier, because they are based on what I call double up. If you start with binary. Binary is based on 2. When you double up, you will get 4. Next time you will get 8. 8 is the number that Octal is based on, but that's not used much anymore. Next time you will get 16. 16 is the number that Hex is based on. Now, you can see that going from hex to binary will be easier. Hex numbers goes from 0 to 15, and binary goes from 0 to 1. So that means that four binary numbers matches one hex number. An example: The hex number F00 again. If you take each number and convert it to binary, it is much easier. 0 = 0 = F = Result = You can now convert the binary number to octal, which is based on three binary numbers instead of four. First, put spaces in between every third to make it easier: 111 100 000 000 You can see that it is the same binary number as above, but it looks different now. Now convert to Octal: 000 = 0 000 = 0 100 = 4 111 = 7 Octal result = 7400 Some people prefer to use binary when converting from hex to decimal. Again, let's take the F00. From Hex to Bin: F 0 0 = Let's split the binary numbers up: 0 * 2^0 (1) = 0 0 * 2^1 (2) = 0 0 * 2^2 (4) = 0 0 * 2^3 (8) = 0 0 * 2^4 (16) = 0 0 * 2^5 (32) = 0 0 * 2^6 (64) = 0 0 * 2^7 (128) = 0 1 * 2^8 (256) = 256 1 * 2^9 (512) = 512 1 * 2^10 (1024) = 1024 1 * 2^11 (2048) = 2048 RESULT = 3840 If you look at the first calculation we did in the beginning, you can see that I came to the same result.

RE: Loopback Interfaces..long reply, read carefully please to [7:38285]
OK, For some reason, my first time of sending this reply got chopped, so
here it is again.
Brian, et al.,
Please Note the following:
***All I wanted to know was: Can the Loopback Interface be used to host a
complete subnet (and the Router make routing decisions with this inteface),
or is its functionality such that it will always respond like an interface
configured with a 255.255.255.255 mask, and 86 traffic not destined for IT
on the same subnet??
I'm not looking for someone to help me make a completely working config for
all routers in this implementation.
The idea is to do such:
!Interface FastEthernet0
! description Connected to PIX Outside Interface, and PIX Inside Interface
is subnet for Data traffic.
! Ip adress x.x.x.x 255.255.255.x
!Interface Loopback0
! description VoIP subnet with VoIP originating/terminating on this
Router... other hosts also placed on the same subnet at a later date, and
connecting via the Ethernet Port which connects to a switch that the other
hosts are also plugging into.
! Ip address 192.168.101.1 255.255.255.0
!Interface Serial0
! NO IP ADDRESS
! Encap Frame-Relay
!Interface Serial0.1
! description Connected to the Internet
! Ip address x.x.x.x x.x.x.252
! interface-dlci 16
!Interface Serial0.100
! description Connected to HQ over PVT FR for Voice traffic
! ip unnumbered loopback0
! interface-dlci 100
! {insert Map-Class Tag here}
!{Insert Route-Maps Here}
!{Insert Voice configuration here... a.k.a. Dial Peers}
!{Insert QoS config here... a.k.a. Map Classes}
!Router EIGRP 1750
!Network 192.168.100.0 Brian
Mark Odette II wrote in message
[EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
OK, I'll make the question simpler.
Can you use a loopback interface in the same respect that you would use an
ethernet interface?
Create the loopback: Interface Loopback0
Assign it an IP with a /24 mask : ip address 192.168.10.1
Configure the subnet assigned to the loopback interface to a routing
process, such as EIGRP or RIP.
Assign many other hosts on a LAN or a WAN an IP address that is in the
same
subnet as the loopback interface.
Replicate the above configuration on Router at other end of FR network.
add subnet assigned to far-end routers' loopback interface to local EIGRP
AS, or RIP; do the same on the far-end routers' config for the same EIGRP
AS
or RIP configuration.
And then, configure FR Subinterface with IP Unnumbered Loopback0, and
route
traffic across the FR network, with the traffic orininating from either
the
Router, or another host (if configuration above is legal) on the subnet
that
is assigned to the Loopback interface.
What I want to do, is configure a VoIP enabled router with a loopback
interface assigned to 192.168.10.1, and several LAN hosts with the same
subnet assignment, i.e., 192.168.10.2, .3, .4, etc., and a /24 subnet mask
for all hosts including loopback interface.
I then want to create and assign IP Unnumbered loopbackX to a FR P-to-P
subinterface.
Create EIGRP AS to route Subnets assigned to loopback interfaces on each
respective router.
Mirror image this configuration on the other end of the wire (FR
Network).
Configure Dial-Peers with VOIP destinations pointing to the loopback
interface of the peer router (other end of the FR Network).
Is this Possible??
The reason why I want to use Loopback interfaces, is because I plan to
assign a separate subnet to the FastEthernet Interface, and don't believe
that the use of the Secondary command will work, i.e., you can't specify
IP
Unnumbered FastEthernet0 and have the Secondary IP address used ip
unnumbered fastethernet0 will use the FastEthernets' Primary address,
which
is not desired.
The Primary Subnet assigned to the FastEthernet Interface will be NAT
Translating with a PIX FW (PIX will be doing the NAT) to hit the Internet.
For Topology description:
Router HQ connects to internet on one subinterface, while connecting to 3
remote offices on a private FR network on a second subinterface.
Router Remote1 Will be connecting to the internet on one subinterface,
while
connecting back to HQ on separate FR subinterface for VoIP over FR traffic
only (no Data traffic)
Router Remote2 will be doing the same as Remote1
Router Remote3 will also be doing the same as Remote1
... So much for a simpler reply. :)
Thanks in advance for everyones' comments.

RE: Question on PIX 501 [7:38246]
You'll need to open any ports that you want passed, no matter the direction. You can do this in bulk by specifying access-list inside permit ip any any and verifying that the access-list is applied to the inside interface with access-list inside in interface inside. This will allow outbound traffic from any inside host and allow established traffic to come back in and reach the originator. You probably don't want to do this in practice since it's playing fast and loose with your security.

The curious (to me) issue was that from the console or the PDM of the Pix I can ping network addresses on both sides of the Pix. From the inside of the Pix, I cannot ping (or browse the web) through the Pix. I cannot even ping the outside interface of the Pix from the inside interface. The specific question is this ... is additional configuration of the Pix required to permit access from the inside interface to the outside interface and beyond? To expand on the topic you and Ole are discussing, is the use of the conduits (or access-lists) required for each and every type of service I want to send from the inside to the outside? I have no problem researching the commands to learn how it is done, I just want to make certain I am on the right path.

When A pings B, A sends ICMP echo-request (number 8) to B, and B sends ICMP echo-reply (number 0) back to A. The PIX does not allow ICMP traffic to come from the outside to the inside, so to change that, you will need to open up for ICMP number 0 (echo-reply). The command for that is: conduit permit icmp any any 0 This is a good way to do it, because then you allow outside devices to reply to your request, but they are not allowed to do a PING themself.

Re: ATM route check [7:38201]
Hi, lane uses svc's to build data-direct connections between LECs, so in principle you can trace the path through all intermediate atm switches by simply doing show atm vc and writing down all the cross-connects on the NNI switches. Needless to say, this may take quite a while... Another method is to simulate (compute) a path by using pnni command: show atm pnni dtl node executed on the atm switch. Below is an example: AMART#sh atm pnni dtl node 25 ubr AMART# Mar 14 21:33:37.933 MET: PNNI: UBR route request from ATM_OWNER_UNKNOWN Mar 14 21:33:37.933 MET: PNNI: To node AMERICA Mar 14 21:33:37.933 MET: PNNI: selected target node 25 Mar 14 21:33:37.933 MET: priority: 2 (25 0) pnni-remote-internal Mar 14 21:33:37.933 MET: PNNI: Compute On-Demand Route Based On Admin Weight Mar 14 21:33:37.933 MET: PNNI: Found A 3 Hop Route To Destination.

Re: Stacker and Predictor? [7:38286]
STAC (LZS) was developed by STAC Electronics, who then changed their name to Hi/fn, Inc., and is based on the Lempel-Ziv (LZ) compression algorithm. Although effective, the STAC compression algorithm uses more CPU resources to perform compression. Cisco IOS software uses an optimized version of STAC compression. LZS is available in Cisco's Link Access Procedure, Balanced (LAPB), HDLC, X.25, and Frame Relay data compression solutions. FRF.9 and IPComp use the LZS compression algorithm. The Predictor compression algorithm tries to predict the next sequence of characters in the data stream by using an index to look up a sequence in the compression dictionary. It then examines the next sequence in the data stream to see if it matches. If so, that sequence replaces the looked-up sequence in the dictionary. If not, the algorithm locates the next character sequence in the index and the process begins again. The index updates itself by hashing a few of the most recent character sequences from the input stream. - Rich - Original Message - From: Cisco Nuts To: Sent: Thursday, March 14, 2002 3:38 PM Subject: Stacker and Predictor?

RE: Management VLANs? [7:38282]
I think Cisco generally recommends that your switch mgmt interface is on a different VLAN than your regular (read: end-user/server) devices. This helps isolate broadcast/multicast traffic so the switch CPU doesn't have to process it - especially critical in networks where there is a high percentage of broadcast/multicast traffic. Additionally, there's a security component to this line of thinking; if you have an isolated subnet purely for switch management then you can restrict (at the router) who is allowed into that network; this is in addition to the various access controls you can employ on the individual switches. A word of caution though...I wouldn't recommend that you have a single mgmt VLAN that spanned your entire network unless you work in a really small shop - this breaks all sorts of rules in the Core-Distribution-Access religion and can be difficult to manage. Last note; I've seen a document (but can't place my fingers on it now) that recommended that you NOT use VLAN # 1 as your mgmt VLAN. Unfortunately it didn't elaborate as to why.

OK, I'll make the question simpler.
Can you use a loopback interface in the same respect that you would use an
ethernet interface?
Create the loopback: Interface Loopback0
Assign it an IP with a /24 mask : ip address 192.168.10.1
Configure the subnet assigned to the loopback interface to a routing
process, such as EIGRP or RIP.
Assign many other hosts on a LAN or a WAN an IP address that is in the
same
subnet as the loopback interface.
Replicate the above configuration on Router at other end of FR network.
add subnet assigned to far-end routers' loopback interface to local EIGRP
AS, or RIP; do the same on the far-end routers' config for the same EIGRP
AS
or RIP configuration.
And then, configure FR Subinterface with IP Unnumbered Loopback0, and
route
traffic across the FR network, with the traffic orininating from either
the
Router, or another host (if configuration above is legal) on the subnet
that
is assigned to the Loopback interface.
What I want to do, is configure a VoIP enabled router with a loopback
interface assigned to 192.168.10.1, and several LAN hosts with the same
subnet assignment, i.e., 192.168.10.2, .3, .4, etc., and a /24 subnet mask
for all hosts including loopback interface.
I then want to create and assign IP Unnumbered loopbackX to a FR P-to-P
subinterface.
Create EIGRP AS to route Subnets assigned to loopback interfaces on each
respective router.
Mirror image this configuration on the other end of the wire (FR
Network).
Configure Dial-Peers with VOIP destinations pointing to the loopback
interface of the peer router (other end of the FR Network).
Is this Possible??
The reason why I want to use Loopback interfaces, is because I plan to
assign a separate subnet to the FastEthernet Interface, and don't believe
that the use of the Secondary command will work, i.e., you can't specify
IP
Unnumbered FastEthernet0 and have the Secondary IP address used ip
unnumbered fastethernet0 will use the FastEthernets' Primary address,
which
is not desired.
The Primary Subnet assigned to the FastEthernet Interface will be NAT
Translating with a PIX FW (PIX will be doing the NAT) to hit the Internet.
For Topology description:
Router HQ connects to internet on one subinterface, while connecting to 3
remote offices on a private FR network on a second subinterface.
Router Remote1 Will be connecting to the internet on one subinterface,
while
connecting back to HQ on separate FR subinterface for VoIP over FR traffic
only (no Data traffic)
Router Remote2 will be doing the same as Remote1
Router Remote3 will also be doing the same as Remote1

maybe I'm making this whole thing too complicated. What if I just put a loopback interface on each router/switch on a management subnet. what I'm trying to attempt is to make my entire router / switching structure easier to access by not having to remember exactly which whole ip address is for which router, rather could say that's router 10 so it's 10.10.10.10 (as an example).

Re: Question on PIX 501 [7:38246]
Once you have your NAT set up, the pix will allow stateful sessions back in through the firewall, ie. If you browse from inside to outside, the session will be allowed back in. Ping (ICMP) is slightly different, it is not a single outgoing session. It is an outgoing packet followed by a separate reply. Your conduits or access lists are required only to allow incoming sessions, or, (in the case of access-lists) if you require to restrict outgoing sessions. My technical grammar may be a little off the mark, but it should clear up the thought process. Regards, Gaz Justin C wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Mark, My original question that I sent to the group somehow got lost. Ole was kind enough to respond to a direct query regarding to some fun I am having with installing a Pix (501) for the first time. My firewall background is SonicWall and Watchguard, both are very simple in configuration and work directly out of the box. I was under the impression it was pretty much plug and play, so I decided to test it by putting it between my PC and the rest of the LAN. However, after the initial setup, the Pix passed no information through it. So I went to a ping to start the troubleshooting. The curious (to me) issue was that from the console or the PDM of the Pix I can ping network addresses on both sides of the Pix. From the inside of the Pix, I cannot ping (or browse the web) through the Pix. I cannot even ping the outside interface of the Pix from the inside interface. The specific question is this ... is additional configuration of the Pix required to permit access from the inside interface to the outside interface and beyond? To expand on the topic you and Ole are discussing, is the use of the conduits (or access-lists) required for each and every type of service I want to send from the inside to the outside? I have no problem researching the commands to learn how it is done, I just want to make certain I am on the right path.

I've used the PDM so far to most of the configuration of my PIX, and it creates access-lists rather than conduits. I know from others I've talked with, that Cisco is moving from conduits to access-lists on the PIX configs... this is the question I configure to allow ICMP any(Outside) any(Inside) = Echo Reply ICMP any(Outside) any(Inside) = Time Exceeded ICMP any(Outside) any(Inside) = Unreachable Does this do the same thing as what you were saying about conduit permit any any X??

When A pings B, A sends ICMP echo-request (number 8) to B, and B sends ICMP echo-reply (number 0) back to A. The PIX does not allow ICMP traffic to come from the outside to the inside, so to change that, you will need to open up for ICMP number 0 (echo-reply). The command for that is: conduit permit icmp any any 0 This is a good way to do it, because then you allow outside devices to reply to your request, but they are not allowed to do a PING themself. If you want PING to work both ways, simply use this command: conduit permit icmp any any Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

Telnet sends one character per packet, by default, which adds up to 64 bytes on an Ethernet segment (it requires padding). DHCP packets are often about 200-300. Routing protocols vary. RIP uses 512. Others use 1500. SMTP varies. It will send 1500 bytes if the message is that long, but often it's not. In other words, you need to know the application to answer the question. I have always claimed, in fact, that an average packet size if a somewhat useless statistic. What you really want to know is if applications are sending what you expect them to send.

OK, I'll make the question simpler.Can you use a loopback interface in the
same respect that you would use anethernet interface?Create the loopback:
Interface Loopback0Assign it an IP with a /24 mask : ip address
192.168.10.1Configure the subnet assigned to the loopback interface to a
routingprocess, such as EIGRP or RIP.Assign many other hosts on a LAN or a
WAN an IP address that is in the
same
subnet as the loopback interface.Replicate the above configuration on Router
at other end of FR network.add subnet assigned to far-end routers' loopback
interface to local EIGRPAS, or RIP; do the same on the far-end routers'
config for the same EIGRP
AS
or RIP configuration.And then, configure FR Subinterface with IP Unnumbered
Loopback0, and
route
traffic across the FR network, with the traffic orininating from either
the
Router, or another host (if configuration above is legal) on the subnet
that
is assigned to the Loopback interface.What I want to do, is configure a VoIP
enabled router with a loopbackinterface assigned to 192.168.10.1, and
several LAN hosts with the samesubnet assignment, i.e., 192.168.10.2, .3,
.4, etc., and a /24 subnet maskfor all hosts including loopback interface.I
then want to create and assign IP Unnumbered loopbackX to a FR
P-to-Psubinterface.Create EIGRP AS to route Subnets assigned to loopback
interfaces on eachrespective router.Mirror image this configuration on the
other end of the wire (FR
Network).
Configure Dial-Peers with VOIP destinations pointing to the
loopbackinterface of the peer router (other end of the FR Network).Is this
Possible??The reason why I want to use Loopback interfaces, is because I
plan toassign a separate subnet to the FastEthernet Interface, and don't
believethat the use of the Secondary command will work, i.e., you can't
specify
IP
Unnumbered FastEthernet0 and have the Secondary IP address used
ipunnumbered fastethernet0 will use the FastEthernets' Primary address,
which
is not desired.The Primary Subnet assigned to the FastEthernet Interface
will be NATTranslating with a PIX FW (PIX will be doing the NAT) to hit the
Internet.For Topology description:Router HQ connects to internet on one

one subinterface,
while
connecting back to HQ on separate FR subinterface for VoIP over FR
