Ip addressing question
Could anyone explain to me why Subnet zero and the last subnet are not normally used?? I see why 2 host addresses are reserved in every subnet (network address and broadcast address), but I never understood why 2 networks are not used. What is the difference between these networks and the networks in between?

Question about Napt
Hi, I was reading RFC3022 about Napt last night, and I still dont understand one thing about it. From what I understand is that Napt allows you to use one single globally unique IP address on the WAN interface of your router, and then a large number of local addresses inside your network which aren't globally unique. Now the router will be able to translate the different traffic streams coming from the WAN according to the port on the packet. So if host A inside the network wanted to communicate with Host B which is on a different outside network, it would directly address the outside site, and the router would catch the packet enroute and change the source IP address to the router WAN interface IP address and also change the source port to a port of the router's discretion. Normally, from what I understand, ports are used to multiplex streams of traffic across a link. If Host A was using two applications and wanted to start a second session with Host B. Would the router allow this? The RFC states "While not a common practice, it is possible to have an application on a private host establish multiple simutaneous sessions originating from the same tuple of (private address, private TU port). In such a case, a single binding for the tuple of (private address, private TU port) may be used for translation of packets pertaining to all sessions originating from the same tuple on a host. How exactly would the applications know which traffic stream was for itself? Also, how many local hosts can the router assign to a single IP address before it has to use a second IP address? Could a company of 10 use a single IP address for NAPT? or would it need to use more than one?

RE: Question about Napt
Wait a second.. How could you have 64000 different people inside using PAT to convert to 1 global IP address? Wouldn't you need 64000 ports on the switch?? I thought that you needed 1 physical port (inside) per logical port translation. For example, I thought that port 2/1 on the switch would be converted to TCP port 1024 on the outside, and port 2/2 on the inside would be converted to TCP port 1025 on the outside.. ect..

Hybrid Routing Protocols
Hi I just a general question about routing protocols, if anyone could help me out here I'd be grateful. When comparing EIGRP to Distance Vector routing protocols, like RIP, the only similarity that I noticed was that the network statements are both classful. Is this the only characteristic that prevent EIGRP from being considered a total link-state routing protocol? Or is there something else I failed to notice?

Thank you Ole, I've been taking a CCNP class at ASM Educational Center in College Park, MD under a CCIE instructor. The book that they gave us for the Routing segment wasn't too good (the Syngress one, it has tons of errors in it), but the instructor is awesome.

Actually there were a whole lot of questions on EIGRP and OSPF in that test. Also, make sure you have a strong mathematical perspective on subnetting/supernetting.

Re: passed the CCNP routing!
Dear Hui, I read the Syngress book for the 640-503 exam. I would strongly recommend that you learn from a different book, because the Syngress is FULL of errors. If you dont have a very good instructor (like I did) to go with that book, then you will walk away feeling very confused. I also bought the examcram book which I thought was somewhat helpful. I didn't actually read the examcram book, all I did was take the tests in the end of all the chapters, and in the end of the book. I think 3-4 of the questions on the test were EXACT matches to 3-4 of the ones in the examcram book. Good luck with your studying, and dont be afraid to take the test. It really isn't ALL that hard. Just make sure you have a strong understand of the concepts.

RE: passed the CCNP routing!
I dont really know of any good books about supernetting/subnetting, but if you were to look, make sure it fully explains it. Find a book that explains it from a mathematical point of view, because that is the essence of supernetting/subnetting. It is pure binary math :) A lot of people who got by on the CCNA by memorizing a number different formulas would have a lot of trouble on the CCNP. They really test you on the CCNP routing exam.

Re: Changes in the Cisco certification structure for CCNA & CCNP Specializations
It says "As of February 12, 2001, new Cisco Security Specialist and Cisco SNA/IP Specialist designations replace the former CCNP and CCDP Specializations."

A few quick Remote Access questions
I've been reading through the Sybex BCRAN book and have a few "quick" questions: First, I understand the theoretical difference between Autoconfigure and Autodiscovery, but in the book, it appears that the different commands do the same thing. For Autoconfigure, the book says "The modem autoconfigure command is used to instruct the router to use this feature. This feature will detect the type of modem connected to the router and then supply the initialization string to the modem-- a process that can require up to five seconds." It sounds as if the modem autoconfigure command also performs autodiscovery functions. Did they really mean to say that the command is modem autoconfigure modem_type ? The second question that I have involves RTS and CTS. The stated function of RTS from the book is "Request to send is one of the two hardware flow control wires. It signals that the DTE can receive data from the DCE. This depends on having sufficient buffers available." The states function of CTS from the book is "Clear to send is the second hardware flow control wire, and it signals that the DCE is ready to receive from the DTE." I previously thought that there were two steps to hardware flow control using RTS and CTS. I used to think that the sending side would first send a RTS message to the receiving side, and in turn the receiving side would send a CTS message so that the sending side would know that the receiving side was ready for data. The thing that gets me with their explanation is that they say that CTS is used by the DCE saying that it is ready to receive, and RTS is used by the DTE saying that it is ready to receive. My impression from this explanation is that it is a one step process, but I still dont see how this would work. How does it really work?? My third question is: What exactly is the difference between ISDN PRI and a leased line T1?? And Finally, my last question is: How the heck do they get the number 1.544 Mbs for the speed of a T1? When I multiply 24 (# of B channels) by 64Kbs I get 1536kbs. 1536Kbs converted to Mbs (1536/1024)is 1.500 Mbs! Where are the other 0.44 Mbs at?? If anyone can answer atleast one of the questions, please do. I know that I'm digging real deep here, but thats how I learn best. Thanks.

Re: A few quick Remote Access questions
Dear Howard, Thank you very much for the response. Everything is starting to come together now. I still have one problem though--- >8000 bps, or every 193rd bit, is used for framing and control. 1536 >Kbps + 8 Kbps = 1544 Kbps = 1.544 Mbps. I see how it works so there would be 1544 Kbps, but 1544Kbps = 1.5078125Mbps (1544Kpbs * (1 Mbps/1024Kpbs)).

question about frame
Hey guys, I just got a quick question about Frame Relay. I've been reading the BCRAN book published by Sybex, and I'm finding the frame relay chapter a bit confusing. A few paragraphs from the Sybex book state the following: "Committed burst size and excess burst size are the two types of burst sizes. Each of these sizes is measured over a specific time interval called the committed rate measurement interval. Committed burst size is the maximum amount of data that the network can guarantee will be delivered during the committed time interval. The excess burst size is the amount of traffic which the user may exceed the committed burst size. For example, take a user who buys a Frame Relay circuit with the following characteristics: 1544Kbs access rate, 256K CIR, 4 second committed time interval. The user is guaranteed a CIR of 256Kbps over a four-second period. The user could transmit 256Kbps for four seconds, and the network would ensure delivery. The user could alternately send 1024Kbps for one second, representing the committed burst. However for the remaining three seconds, there would be no guarantee of delivery for the excess burst traffic." When the author says "The user could alternately send 1024Kbps for one second, representing the committed burst.", is he defining the committed burst as any speed above the CIR that does not exceed the total amount of information (256Kbps * 4 second interval = 1024K, total info) allowed to be sent during the time interval ? I always thought of the committed burst rate as a rate of information agreed upon with the Telco. For example, I thought you could get a CIR of 256Kbps and a burst up to 512Kbps, or a CIR of 256Kbps with a burst up to 1.544 Mbps. Could anyone do me the favor of defining committed burst rate and excess burst rate, and while you're at it differentiate between the two? :) Thanks, Fred Danson _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Equal cost switching

This operation yields one of four results: (0 0), >(0,1), (1 0), >or (1 1). Each of these values points to a link in the >Fast EtherChannel >bundle. That really makes sense. I always pictured this process as the first frame in a stream being sent down the first wire, and the second frame in the stream being down the second wire, third frame being sent down the first wire.. ect.. The way you explain it makes more sense because this way the switch wont have to think about which wire it last used to send a frame, but instead it does a simple calculation. So in essence, if you had 8 wires in an EtherChannel, but most of your traffic was going only between 2 servers ( Server1 <- Switch-> Server2), then only 1 or 2 of the links would be used based on the X-OR calculation? So 6 of the wires in the bundle would be wasted? Is this accurate? Also, I've never really thought about it, but is it possible to have a number of wires in an EtherChannel that are not a power of 2? I.E. 3,5,6,7? It wouldn't seem possible if each wire was assigned a value ((0,0), (0,1), (1,0), (1,1)). If you had 3 wires in an EtherChannel, then the 1,1 value would not be used, and to me, I would think that the Switch would get confused if all the values didn't have an assigned value. One more thing guys! Don't let the hype about fool-duplex full you! If you have a full-duplex 100Mbps connection, you dont REALLY get 200Mbps bandwidth, you just get 100Mbps in both directions simultaneously.

Remember everyone has *something*. I don't really agree here. You wont find that everyone has something to offer. There's a guy at my work who doesn't know a thing about his job, but knows how to fool other people into thinking he does. Whenever we have to troubleshoot something, all he does is slow us down.

Many young people in the computer industry are excellent network troubleshooters, but horrible "people troubleshooters". If a person resents you, there has to be a reason for it (just like with any computer problem). Theres a solution to every problem, and you'll probably find yourself "troubleshooting" people problems more often than computer problems. You have to find out why they resent you, and try to fix it. Some people just dont trust other people when they first meet them, so ,in many cases, you have to take the initiave in establishing rapport. _

OSPF multicast addresses
Hi everyone, I am trying to figure out in which situations certain OSPF multicast addresses are used. The two multicast addresses used in OSPF that I know of are 224.0.0.5 and 224.0.0.6. From my understanding, in a broadcast network, all ospf routers send link info to the DR/BDR with the address of 224.0.0.6. The DR will then send all the data back to the DROTHER routers using the address of 224.0.0.5. Is this correct? I previously thought that the DR sent the data back using the address of 224.0.0.6, but this wouldn't work because the DROTHER routers don't listen to that address. Is this also correct? _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: EASY ?? FOR MOST OF YOU
Im not really an expert on this subject and I'd love to learn more about it, but didn't they also change the maximum network span too? Aren't the two factors in this equation maximum network span and minimum frame size? If they increased the minimum frame size 8x then it would make sense to decrease the maximum network span by a multiple of 0.8 (205/1.25). This would seem to work, but im not sure about it. If I am way off someone please correct me. Also does anyone know where exactly I could find the IEEE specs on gigabit ethernet ?

That's true, so he pretty much had 2 choices in that situation. He could either switch the OSPF network type to multipoint on the hub and the spokes, or he could insert neighbor statements. Both ways would work.

ISDN simulator problem
Hey Group, I just got my Teltone ISDN simulator in the mail, but I can't seem to get it working. The simulator, by default, is setup to use Basic-ni1. I connected both of my routers directly to the simulator using straight-through cat5 cables. I then typed no shut on the bri0 interfaces and set the isdn switch-type as basic-ni1 on both of the routers. When I type show isdn status, I get this: Router#show isdn status The current ISDN Switchtype = basic-ni1 ISDN BRI0 interface Layer 1 Status: DEACTIVATED Layer 2 Status: Layer 2 NOT Activated Layer 3 Status: No Active Layer 3 Call(s) Activated dsl 0 CCBs = 0 Total Allocated ISDN CCBs = 0 With my basic configuration, shouldn't the layer 2 be working? Can anyone spot any problems with my setup?

Re: ISDN simulator problem
Hey guys, I found out my problem. I am using a Demonstrator, even though the person who sold it to me told me that it was a Teltone-2000. To compound the problem, one of my straight through cables only has pins 1, 2, 3, and 6. I'm glad I had a few NT1s sitting around.

Re: Cannot ping switch in a inter-vlan setup??
Just so you know, you don't HAVE to create a new subinterface. The vlan number is not dependant on the subinterface number.

Re: OSPF virtual links
The changes you listed really won't do anything. As long as the IP address on the interface falls into the network + wildcard mask range used in the network statement, it will work fine. You can check to see if the interface is active in the ospf process using the show ip ospf interface command. >From: "Arthur Simplina" <[EMAIL PROTECTED]> >Reply-To: "Arthur Simplina" <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: Re: OSPF virtual links >Date: Sun, 08 Apr 2001 20:15:15 -0400 > >My comments follow below.

2 8mb flash partitions
Hey Group, I noticed that one of my 2500 routers which has a total of 16mb of flash on 2 SIMMs has the flash split up into 2 partitions. If I wanted to put an IOS on the router which was larger than 8mb, would it work? Is it possible to span a file over multiple flash SIMMs?

Cost effective home ATM lab [7:482]
Hey Group, I've been considering putting ATM in my home lab. Right now, I only have 4 2500 series routers and 1 4000 series router. As far as I can tell, the Lightstream 100 ATM switches seem pretty reasonable (around $1250 on ebay). When it comes to buying ATM DTEs, do I have any other options other than purchasing 3600 series routers and putting a NM-1A-OC3MM= modules into them ? This solution would be very costly. I also noticed people selling 7000 series routers with CX-AIP-SM modules. This combo would be considerably less, but the question is: are CX-AIP-SM modules compatible with Lightstream 100 OC3 modules? If they are, would I be missing anything if I went with the 7000 and not the 3600 ? Are there any possibilities that I havn't thought of?

BGP's Next-hop-self [7:568]
Hey Group, I'm doing a little BGP lab here in my home, and I'm running into problems when trying to get the next-hop-self command to work in between IGP peers. Here's my topology: r2503 --EBGP-- r2523 --IBGP-- r2504 --IBGP-- r2501 AS200 AS100 AS100 AS100 r2503 has no problem advertising its loopback (1.1.1.1/24) to r2523 through their EBGP connection. r2523 then sends the 1.1.1.1/24 route to r2504 while changing the next hop to r2523. The problem is that r2504 cannot send the 1.1.1.1/24 router to r2501. I assumed that the next-hop-self command would be important in this situation, but it isn't working. Is there anything that I am doing wrong here? Here are the configs (without unnecessary info): hostname r2503 ! interface Loopback0 ip address 1.1.1.1 255.255.255.0 ! interface Serial0 ip address 192.1.1.1 255.255.255.0 ! router bgp 100 network 1.0.0.0 neighbor 192.1.1.2 remote-as 200 ! -- hostname r2523 ! interface Loopback0 ip address 2.2.2.2 255.255.255.0 ! interface Serial1 ip address 192.1.1.2 255.255.255.0 clockrate 64000 ! interface Serial2 ip address 193.1.1.2 255.255.255.0 clockrate 64000 ! router bgp 200 network 2.0.0.0 neighbor 192.1.1.1 remote-as 100 neighbor 193.1.1.1 remote-as 200 neighbor 193.1.1.1 next-hop-self no synchronization hostname r2504 ! interface Loopback0 ip address 3.3.3.3 255.255.255.0 ! interface Serial0 ip address 193.1.1.1 255.255.255.0 ! interface Serial1 ip address 194.1.1.1 255.255.255.0 ! router bgp 200 no synchronization network 3.0.0.0 neighbor 193.1.1.2 remote-as 200 neighbor 193.1.1.2 route-reflector-client neighbor 193.1.1.2 next-hop-self neighbor 194.1.1.2 remote-as 200 neighbor 194.1.1.2 route-reflector-client neighbor 194.1.1.2 next-hop-self hostname r2501 ! interface Loopback0 ip address 4.4.4.4 255.255.255.0 no ip directed-broadcast ! interface Serial0 ip address 194.1.1.2 255.255.255.0 clockrate 64000 ! router bgp 200 no synchronization network 4.0.0.0 neighbor 194.1.1.1 remote-as 200 Thanks in advance, Fred _ Get your FREE download of MSN Explorer at http://explorer.msn.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=568&t=568 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
NAT capabilities of small Netgear/Linksys router [7:657]
Hey Group, I am considering buying a small Netgear/Linksys router so I can link my computer, terminal server, and power supply to the internet through my cable modem using NAT (actually it would be considered NAT overload or PAT, but Netgear and Linksys call it NAT). All of the Netgear/Linksys advertisements that I have seen are very vague about their NAT capabilities. My goal is to have the ability to telnet to any of my inside devices from an outside location. To do this, I would need to setup static PAT tables, right? Does anyone know if any of these small routers support this?

reverse telnet problem [7:1454]
Hey Group, I seem to be having a small problem with reverse telnet! Here's what's configured- I setup my terminal server (2511) with a loopback of 1.1.1.1, ip host commands for each router connected through the async ports, and transport input all & no exec on line 1 8. Here's the problem- when I first do a reverse telnet to any one of my routers, something funny happens! For some reason, the text comes onto the screen very slow, and I can't type any commands. I appear to be telnetted into the routers, but I still can't type anything! There is one exception though. The problem occurs only when I reverse telnet to my 2500 series routers. The problem does not occur when I reverse telnet to my 4000 series router. Does anyone know what the problem here is? Am I forgetting a command or two? Also, could anyone explain the purpose of the no exec command (I just read it in a book, but never really though about it) on my async lines? Thanks in advance, Fred P.S. All of the routers, except for the 4000, are running version 12.0 enterprise IOS _ Get your FREE download of MSN Explorer at http://explorer.msn.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=1454&t=1454 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Certification Ego! (was Failed CCDA) [7:1929]
One thing that I ALWAYS notice when asking someone else for advice is that they ALWAYS advise me to take the same path that they did. No matter how dissimilar out situations are, I will always be advised to take the same route that they took. For example, when I was finishing up with my CCNP certification, I asked for advise from several other people who also were finishing their CCNP certifications. A few of the people that I asked were MCSE's and they all told me to go for MCSE before CCIE. Their reasoning was that I wouldn't be able to understand the WAN unless I had a solid understanding of the LAN. Now I do think that there is some logic to this statement, but I definitely did not think that it made sense to put CCIE on hold for 5-6 months just to learn more about Microsoft. I think their real reasons for giving me such crappy advice is that they're afraid to admit that they made a mistake. If they suddenly realized that they wasted 7 months learning about Microsoft, would they be willing to admit this? I really doubt it! They would tell me to do what they did so they can boost their own egos! Or on the other hand, they wouldn't tell me not to do what they did because they would hurt theie egos. So now, instead of blindingly taking someone's advice, I take a realistic look at all of my options. Being only 20 years old, I was advised by many "experienced professionals" to give it a few years before attempting the CCIE. Does it really take that long to learn all this stuff? I really don't think so. There is an abundance of information out there, and all you have to do is put in the extra effort to learn it. Heck, I didn't even know what a Router was until about 7 months ago, and I already have CCNA, CCDA, CCNP, and CCIE written. My point here is, don't listen to anyone that isn't in the same situation as you! Take a realistic look at your options and go for it! Fred Danson P.S. - I have a problem with the statement "youth is a unique illnes that heals with time only". From what I hear, the older portion of the CCIE candidates typically struggle with the time constraints on the CCIE Lab. To my knowledge, cheese and wine are the things that improve with age.

Re: CCIE depreciation in 2 years [7:1882]
The rate of new CCIE's has recently been increasing and I'm sure it will continue to increase. The real question here is, how fast will the demand for these CCIE's increase? If the demand increases faster than the supply, then the salary for CCIE's will also increase. When I think about the future, I see legacy voice systems being completely replaced by VOIP networks. I see third world countries jumping on the internet bandwagon. I even see myself programming my home oven from work so it will be ready by the time I get home. The future will probably be revolved around computer networks, so getting the CCIE would be a step in the right direction.

Re: Certification Ego! (was Failed CCDA) [7:1929]
I do agree with you on many points Jason, but not all networking jobs deal with the LAN. Eventually, I do plan to learn about Microsoft. UNIX, Ect But being in my current situation, my best course of action would be to work on the CCIE. In my earlier writing I was trying to emphasize the point that there are many paths to take, but there is only one best path. I could choose to work on learning the LAN now, but it is my belief that working towards the CCIE would benefit me the most in the long run. I definitely do not plan to just get the CCIE and then avoid the LAN alltogether. That wouldn't be a very wise move. It's common knowledge that any lab-certified CCIE is pretty much guaranteed six figures. In some cases companies recruit CCIE's just to achieve silver or gold status with Cisco. Also, many positions within ISP's do not require any LAN experience. Fred >From: "Jason J. Roysdon" >Reply-To: "Jason J. Roysdon" >To: [EMAIL PROTECTED] >Subject: Re: Certification Ego!

Re: Certification Ego! (was Failed CCDA) [7:1929]
I do agree with you there. Cisco's restructuring of its partner program will decrease the demand for CCIE. It probably isn't as easy these days for all new CCIE's to start with 6 figure salaries. As far as showing accomplishment and ability, doesn't obtaining the CCIE certification show exactly that? Being a part of this small elite group is a major accomplishment, and requires incredible skill to achieve. So doesn't this certification prove that the person has what it takes?

Re: 500-CS...HELP!! [7:2414]......here is my 500-CS config [7:2472]
I don't think your problem has anything to do with the "no exec" command in your config. I also use the "no exec" command for my async ports and it works great. I think the problem lies within these commands. ip host R1 2003 1.1.1.1 line 1 no exec monitor transport input telnet transport output telnet Notice that the port you specified was 2003. Port 2003 maps to line 3, not line 1. You don't have anything configured for line 3, so the reverse telnet session will not work for it. I would either try changing the port to 2001 or change the "line 1" command to "line 1 3" Let me know if this does any good.

Re: CCIE prep - review lab inventory and budget [7:3908]

Re: CCIE prep - review lab inventory and budget [7:3908]
If your $4000 budget isn't going to move, you always have other options. Another factor here is- how long you are willing to wait? Every once in a while you can find someone to buy direct from. They might not know the street prices or miight not care how much they get for their equipment. Either way, you win. If I had $4000 to create a Lab from scratch, I would probably shoot for a setup like this: $2509- $800-$900 $2523- $800-$900 $2502- $400-$450 $2501- $500-$550 $2503- $550-$650 $2504- $425-$525 hub&mau- $30-$40 Total- $3505 - $4015 Use the rest to buy cables, and mabye another 2501/2502. Take your time when purchasing from ebay. You can sometimes find very good deals! Also, look for deals that include cables & high dram/flash. They don't normally influence the price much. You might even be able to sell back some of the flash to save yourself some money. When you're on a limited budget like $4000, your strategy is quantity, not quality. If you spend half the cash to buy a 2901, you wouldn't have enough cash left to get a decent (IGP/BGP, DLSW, ect.) lab going. You also should look to create a lab that will scale for you in the future. Even though you don't have an ISDN simulator now, you have the routers available in case you decide to purchase one in the future. I think the next step for a lab like this, money permitting, would be to buy an ISDN simulator. They are a little cheaper than a 2901, and they let you do a lot more. I wouldn't even consider buying a switch. Once you have the money, go ahead and get a 2901/5000 (the prices for these 2 don't differ much). For now, you can get a hub or 2. If you need VLANS, buy more hubs. Add a 2513 and you could do most of the fatkid labs!

CCIE vs NP/DP w/experience [7:3986]
I think years of experience does not always translate to ability. Some people get very comfortable with their positions after they achieve NP/DP status. Some continue to learn, some don't. It is hard to gauge a person's ability simply by their years of experience. On the other hand, CCIE's have proven themselves in a grueling 2 day lab. CCIE's are also guaranteed to be proficient in a wide variety of protocols. Also, don't forget that Silver/Gold partners need them. When you look at it from an employer's perspective, you have to remember that most of these people don't know much about networking. They like to see big certifications. The bigger the better.

Re: ccnp lab [7:3975]
My mistake, I thought it said CCIE, not CCNP. Anyways, for your miniumum CCNP lab, you could probably do it with 2 2501's, 1 2502, and 1 2523. But, do you consider ISDN as a part of your CCNP lab?

Re: Gear for CCNP and CCIE preperation! [7:4058]
I've spent a great deal of time looking for the best prices out there and have found that almost all companies charge atleast 20% more than people on ebay. Even better, if you can either manage to buy directly from a person whose dumping their lab or find a failed dot-com auction, go with that! In most cases, your best bet is to go look on ebay. Goto www.ebay.com click on Network,IT click on Cisco type in the item you're looking for then click "Search Completed Items" With that information, you should be able to establish a good baseline for router/switch pricing. >From: "JC" >Reply-To: "JC" >To: [EMAIL PROTECTED] >Subject: Gear for CCNP and CCIE preperation!

cost effective voice solution (for lab) [7:4585]
Hey Group, I've been looking into possible voice setups for my CCIE practice lab. I'm planning on buying either a 1750 with a VIC-2FXS or a 2620 with a NM-1V and a VIC-2FXS. My question is, what is the minimum hardware/software requirement for both the 1750 & 2600 routers to do voice? If I buy a 1750 from ebay, do I need to also buy a DSP? Is this absolutely necessary? Also, for the 2600 voice setup, would I need anything other than a NM-1V and a VIC-2FXS? Do I need a special type of IOS?

Re: ATM for home lab: MM or SM? [7:6077]
>From what I've seen recently on Ebay, the prices for 4500/4700 SM modules have been cheaper than 4500/4700 MM modules. Your cabling won't affect the upper layer protocols, so the cheaper cable is the best choice. Also, I rarely see SM modules in the LS100 switches advertised on Ebay.

As far as I know, the 2620 is the cheapest router out there with inter-vlan routing capabilities. The 1700 series router also has fast ethernet, but can't route between vlans.

RE: Certification Statistics [7:13477]
I know of many people, including myself, who first pursued the CCNP and soon after got the CCDP. After getting the CCNP, the CCDP is only one test away, so it makes sense to put that extra couple of study weeks in for another certification. I also have a hard time believing a set of statistics that has no source. Do you think people write research papers without citing their sources?? Who would believe them??

Re: CAN NOT PING TO ITSELF ON BRI [7:22030]
Hey Grad, R1 and R2 need dialer maps to their own IP addresses. On each router, create a dialer map that points to the local IP address and remote phone number.

Re: CCIE Written - scoring method [7:24272]
I'm pretty sure that Talbot is correct about that one. When I received my score report, it was in percentage units (1-100) and not a weighted score. The exam that I took was before the recent change, but I assume that it's still the same.
