Re: CCIE Questions...
I agree with your answers excpet for #1. Just because a transport layer protocol hasn't been specified, I don't think we can assume UDP. I would have to guess that the original host retransmits.

Definately a good point, although RIP uses UDP port 520 and EIGRP uses multicast port 224.0.0.10. Multicast packets are baesd on UDP. I wasn't thinking ICMP and IGMP...

The BGP routing table itself takes up less than 20MB of memory last time I checked (only a couple months ago). I don't have access to a router running full BGP routes right this moment but someone should verify this. I am fairly certain it is less than 20. So, you can run it just fine on a 3640 with 128mb. I completely disagree with this "experienced" CCIE. However, his routers may have several other services running on them that use a lot of memory. A 3640 with 128mb used simply as an Internet router running BGP will have no trouble now or in the near future. Does anyone have a 3640 w/BGP that could provide some current stats?

A CCIE, experienced in the service provider market, just recently told me that a 3640 *might* be OK at first, but it would really be a strain to keep the entire routing table. His reasoning is that 128MB RAM barely covers the requirements and will allow no room for growth.

Re: Two WAN Links
I disagree. While that type of load balancing works fine in a LAN environment, that's not the way you want your internet traffic flowing. Now it's possible for your traffic to leave ISP1 and come back from ISP2, which pretty much blows your symmetry. If you have multiple subnets, you can advertise some to ISP1 and set local preference for those subnets to go out ISP1. You can then do the same for ISP2. This of course is a 10,000 ft. example. Bottom line is, you need to get together with both your ISP's...

Silly question... I was always under the impression that routers wouldn't retransmit. What about switches? Will they retransmit in the case of collisions, or do they leave it up to the hosts?

Re: stupid questions
There is one way to do this. You can create a Bridge Group Virtual Interface (BVI) . Please see the following URL to get you started: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/inte r_c/icdlanin.htm You can search cisco's website for more details.

Re: 7204 router requirements [7:4982]
Considering there are different I/O controllers and different NPEs (now a NSE) then I would say they come separate. You have to determine the number of interfaces on the I/O you want, and what level NPE/NSE you want. The only thing that actually comes with the chassis is a power supply, 1 power supply, if you want a second you have to order that also. Obviously Port Adapters (PAs) are a order by need basis. Hope that helps.

Re: BGP mesh
Halabi has the solution as usual. From his first edition book, page 129.

High collision rate on 2600 ethernet port

IGRP Routes - Classless Networks with Tunnels [7:47415]
How feasible is this, and has anyone tried it? R1 is connected to R2... in my case, it is an Ethernet link. The link is on the 172.16.64.0 network with a 24 bit mask. R1 has several subnets in the 172.16 major network, but with different masks. In my case, 24, 28 and 29 bit masks. R2 sees all of the networks with the 24 bit masks, but drops the networks with the odd masks.Basic classfull rules observed. The goal it to get the 28 and 29 bit masks to R2 WITHOUT the use of SUMMARIZATION. If I create a tunnel between R1 and R2 with a subnet of 172.16.81.0 29 bit mask the networks with the 29 bit masks show on R2. As soon as I create the second tunnel to take care of the 28 bit masks, the /29 routes disappear and the /28 doesn't make it. On R2, I am making the tunnels passive to prevent loops. Shouldn't this work? Am I missing something. Again, the goal is to get the networks with the specified subnet to appear on R2 without summarization. Comments are appreciated.

Re: IGRP Routes - Classless Networks with Tunnels [7:47415]
Again, R10 is running OSPF and IGRP, with mutual redistribution. R5 is only running IGRP. My goal is to get routes with native subnets (as shown on R10) within the same major subnet into R5. Without summarization. Default network, static routes and policy routing doesn't count either. Keep this in mind - a more practical example of this would be if the link between the routers had a /28 mask. How would I get the /24s into IGRP? We cant summarize the /24 because the bit boundary goes the wrong way. Here is the info on my config, the routing table and debug Note that the route 172.16.32.0 /28 and 132.16.40.0/29 are on R10 with the correct mask. The debug on R10 shows these routes being advertised out the correct tunnels. When R5 gets the routes, they are both installed with the /28 mask! Look at the Route table, note that 32.0 shows it was advertised by 172.16.82.1 from Tunnel 2. The route table shows 40.0 came from 172.16.81.1 but doesn't show the interface! Now take a look at the debug on R5, it shows that both routes came from Tunnel 2, but have different source addresses. 172.16.81.1 should be sourced from Tunnel 1. Since they both come in tunnel 2, the routes get installed with the tunnel 2 mask. As a follow-up, I swapped the subnet masks between the two tunnels. R5 still shows the routes came through Tunnel 2, but now they have the /29 mask. Comments?

Re: Rogue Wireless LANs [7:47287]
NetStumbler is good for "War Driving" and finding potential customers. And you don't have to hack or access someones network to do it. When you approach a potential customer that has an open access point, all that needs to be said is that you were doing a site survey for another customer in the area, building, etc. From the survey, you identified their system, and the appliaction also detected the lack of security. I think this is closer to driving down the street to see who leaves their doors open, rather than going to each house and seeing which closed doors are unlocked.

Re: Certifications on resumes
On the cover page, or under the resume "qualifications section", I will list CCNP, CCDP (only the highest certifications received). Same goes for listing MCSE and not MCP, or CNE and not CNA. At the end, under education and certifications, I will list each certification with the date it was completed. This way it keeps the letters at the end of the name short - the technical people that review the resume will know what's going on when they read it, and all the other info is there for the HR and recruiter types. I also think it shows how quickly or slowly the certifications advance.

Re: Subnet question
The 20 bit prefix extends four bits into the third octet (176). 176 in binary is 1011, so with the mask the address ends at 1011. You want to use the next four bits for subnetting (last four 0's) This gives the range of 1011 (176) through 1011 (191) providing 16 subnets with 256 addresses in each subnet. Typically the first and last subnet are not used, toss out 176 and 191, this leaves 177 through 190, each with a 24 bit mask. (We started with 20 bits, and we added four bits for our own subnets). Looking at the possible answers, the following fall in this range. C) 172.16.183.0/24 F) 172.16.190.0/24 Ed _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: CSU/DSU question

ESF/B8ZS is the most common, however SF/AMI is still around. A local carrier here normally provisions their lines (across town for example) for SF/AMI unless the customer requests otherwise. PPP vs. HDLC refers to the line encapsulation, or what the routers use to communicate. This is independent of the line coding (ESF/B8ZS). If you are talking Cisco to Cisco equipment use HDLC.If you are talking Cisco to something else, PPP is the way to go since Cisco's HDLC is a proprietary implementation. (PPP is common when talking to ISP's. Even if they have Cisco gear because it makes PPP their standard).

Re: Token Ring Crossover Cable???
Alex, Token ring must use a MAU or token hub to insert into the ring. All stations wishing access are connected to this ring. The ring is maintained through the MAU or token hub. Electronic relays hold each station into a loopback state until a voltage signal is sent from the workstation wishing access to the ring through MAU/Hub. The voltage signal in turn activates a relay that inserts the token ring workstations connection onto the ring. This insertion process into the ring is the reason that a crossover cable cannot be used for connecting two token ring stations in the same manner that you can use a crossover cable for a direct connection between two ethernet workstations, simply passing data across a segment. I didn't go through and check out the link but what is happening in Scott's diagram below is that the Bay Centillion 100 Switch is serving the purpose of the MAU/Hub for insertion into the ring. The Centillion Switch allows for each port to be it's own ring. (please correct me if I'm wrong there Scott) Token Ring uses pins 3,4,5,6 whereas Ethernet uses pins 1,2,3,6. Thus your crossover requirement using 3,4 crossed and 5,6 crossed.

Re: Rip over frame issue
Nigel... take another look, I don't think its split-horizon, router 2 is only a frame switch. That would make it strictly a peer config, not hub and spoke. Next, please post the configs of R1 and R3. What IP addresses are on R3 for S0 and L0? If you have the same networks on both R1 and R3, I don't think you would have any RIP routes, because all networks would be directly connected. Also, is this RIP v1 or v2? With RIP v1 , when receiving information about routes within the same major network, hosts and routers assume the same prefix length as that on the incoming interface of the route information (assuming it is not in the same major subnet). The subnet mask of S0 in your config would be fairly critical. If the 172 address has a 16 bit mask on R1, and S0 has a 24 bit mask, the 172 route on R3 will appear with a 16 bit mask.Again, need the configs to see what is happening. I'm not quite certain how it would be handled if you have the same subnet defined on both routers I kind of assume that since it should have a directly connected route, the RIP route would be discarded. Using the 'debug ip rip' command, you can actually see the update sent by the router. I put together a lab to better understand RIP, you can find the lab and results with links to CCO at http://omaha.ciscousers.org/lab/lab_challenge.htm Ed _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
CCIE Written Passed
I finally made a passing mark for the CCIE Written with a 79%. Four days ago I missed the passing score by only 3%. With the encouragement of several people here in GroupStudy, co-workers and friends, I was convinced to reschedule. >From my original exam, I scored very low in areas that I thought I would have been comfortable in. I believe my comfort level contributed to those poor scores. Many have said it before read the question, read it again. You should know the answer before you look at the possibilities. After you have made your selection - read it again and ensure it is justified. For studying for the exam, I really don't have much more to offer than what has already been posted elsewhere on the list other than these comments: I believe the "CCIE Study Guide" by Giles provides an excellent presentation on layer one and two topics for each of the technologies (Ethernet, Token-Ring, FDDI, etc.).

Re: The rules have changed...
No, the rules are still the same as they always were. Over a year ago a Cisco SE manager told me that buying used products such as those on ebay were "shady" at the least. He said flat out that hardware could be resold, but without the IOS. The IP only feature set can be obtained for less than $20 from an authorized reseller.The only exception to this rule, and is still a very gray area, if the IOS is in ROM, such as an AGS+ without flash, or a product that has reached end of life and the software component is no longer being sold.

Re: CCIE Written Test - retraction
This does cause a bit of confusion I took the CCIE writen twice. I saw the same question on each test. It was in the format of select all that apply. After each test, I looked and looked on CCO to find the possible answer. I researched each of the possible answers that I was presented... and still was unable to find the correct "Cisco" answer. I do like to know where I went wrong - how can I ask this, without violating the NDA? I mean exactly where is the line that will violate the NDA. How many have read version 7 of the Cisco Career Certifications Agreement? In the agreement they make a very broad statent regarding "proprietary inforamtion" that includes: Section 6... "questions, answers, worksheets, diagrams, lenghth and/or number of exam segments and/or questions, or any communication, including verbal communication regarding or related to the exam..." In the broadest sence, I take this to mean, if it was on the test, we can not discuss the topic as it relates to the test.If this is the case, everyone on the list is guilty! Case in point, If I took the test, and saw a question that is related to decoding the RIF, and someone is going to take the test asks "how is the RIF put together." Under the agreement, that would be confidential. Even if Cisco has previously disclosed this information! Hmmm... even in Secion 8, Conduct of Business, of the agreement, "... shall conduct his business in a manner which reflects favorably upon the products, services, reputaion and goodwill of Cisco..." Does this mean that if we work for a reseller, and a customer asks us to compare Cisco's product X to Competitor's product Y, that we have to say the Cisco product is better? I mean if we say that the competitor's product is better, it dosen't "refelct favorably" upon the Cisco product, even if it is true! The above are taken to the extreme. In my mind, a violation is if I ask "I had this question on the exam, what are the answers". Or if I say "I had the following on my exam" If someone asks a question, with the intent of learning the technology, and not to just pass the exam, I will help where I can. Of course, the grey area of violating the NDA is out there somewhere.

Re: Frame Relay...Inverse-Arp..?
Yes, you are correct on both counts. 1. Both Caslow's book and Cisco's documentation state the same - if a map is used, inverse arp is disabled for that dlci for that protocol on that interface. 2. If you set up a lab to prove this, you can't. I did the same, and got the same results as you. Creat the map between the spokes, save the config and reload. When everything comes up, both static and dynamic entries are in the cache. I attended anohter class from Mentor, and asked my instructor about this. He asked Bruce, and the inital answer "IOS bug". I ran my lab using both 11.2 and 11.3 enterprise, with the same results. Bruce was to get back with me with more specifics, but I haven't heard yet. I will definately ask when I attend ECP1 in April. If someone attends this class sooner... maybe they can ask. As far as using it in a lab if I used maps, I would also specify no frame inverse-arp. (I think version 12 automatically adds this).

Re: Layer 2 Addressing
Neil, How did the canonical/MAC issue arise, and why is it so confusing? I think it was a mistake. A mistake made because we are all guilty of using terminology that means different things to different people. We often do not bother to define something because it is so "natural" that "everyone knows it". Making this mistake is probably how the definers-of-standards and the manufacturers-of-hardware got us into this little mess. I'm going to try to avoid terms like: "endian" (big and little), memory (computer and adapter), "significance" (most and least significant) unless essential. Most issues of memory-addressing --- on the basis of byte, word, integer, string, or whatever --- are only indirectly related to this question. So what are we left with? 1. Sequential transmission of bits on the wire. 2. Representation and identification of these bits, on paper, in the standard 3. Representation and identification of the bits-within-a-byte, on paper, in hardware documentation of a computer. To be more specific, the first issue is: sequential sending of a frame of bytes, one bit at a time, so that the collection can be identically reconstructed at the receiver. So this first issue is not a problem as long as whatever-we-do at the sender is reciprocated at the receiver. The second issue is also simple. LAN standards involve definition of meanings of various parts of the bit-stream. To explain what they wanted, the definers-of-standards had to represent their concepts on paper. To represent the bit-sequence, they wrote down bits from left-to-right. Left-to-right, naturally, because --- in western culture --- our time-sequence is left-to-right for reading/writing. As part of the standard, the beginning of the frame includes an address, and the standard defines that the first bit (first, in time sequence, naturally) of the address denotes whether the address is multicast. Because of the way they wrote it down, this "first bit" was the left-most bit. As an example, just take a possible first byte and write it down on paper: 01000101 The first bit of this first byte has the value zero, which the standard defines as meaning that the address is not multicast. The definers-of-standards decided, naturally, to number the bits in the same left-to-right sequence. It would have been very strange for them to have decided otherwise. They assumed that this "natural" numbering would be fine. And it is, until a hardware engineer has to implement it. Now for the third part. Manufacturers-of-hardware also represent bits and bytes. They also enumerate bits-within-a-byte to allow documentation of their product. HOWEVER... Within a computer, there is no inherent time-sequence to guide the numbering scheme. Within a computer, each byte is transferred "in parallel". No bit arrives before or after any other. There is no "natural" direction for numbering. Most hardware designers number the representation of their bits-within-a-byte from RIGHT-TO-LEFT. So put yourself in the position of the designer of the adapter. He has to serialize each byte. He has a quick look at the standard and sees that the bits on the wire are numbered in an ascending sequence. So he builds a bit of kit to do it. To send the byte above, most computers then have to transfer this byte: 10100010 (If ever he finds out, a good hardware designer knows that any complaint is just one of many, many, many issues that whining, lazy programmers are always dredging up, to try to get hardware engineers to do their jobs for them.) ;-) So, I think that is how the problem started... Then it was made worse... Despite the fact that LANs work perfectly well with this anomaly, the inadequate definition in the earlier standards (802.3 and 802.4) was addressed in the later ones. For 802.5 and FDDI the definers-of-standards insisted on serializing from the left-most bit of (most) computers' representations. If they had just left it the same it probably would never have been important. After all. how important is it to know whether the parity bit for async serial goes first or last? Anyway, look on the bright side, it makes various forms of mixed-media bridging more entertaining.

Like I said, these are basic and dont provide features like stateful packet inspection, filters based on TCP/UDP, etc. I also believe they have a limit of something like 10 ports active per connection unless you do a passthrough, but that sort of defeats the purpose of the firewall. Watchguard also makes a product that I think is better, but it costs about $370. It provides both NAT and PAT, and you can filter based on source/destination addresses and port numbers. The first year of "managed security" is also provided... although giving up control has overtones of Big Brother but hey... its a service for people that dont know firewalls.

(depending on where I am in the scale) It boils down to the point where your skills are more important to one employer than another, and that employer is willing to show it. For me to leave one job and go to another, so same responsibilities and same pay, there must be something extremely wrong with my present employer. On the other hand... moving to a new job often means new responsibilities and challenges. If I am happy where I am, the potential employer needs to provide an incentive for me to leave... and to do that I typically I look for at least a 10% - 20% jump in pay.

Frame Relay Map Help
I am working through Caslow's Bridges Router and Switches book and I am trying to get a firm understanding of frame-relay. I have generally recreated the lab on page 126 with the minor changes of adding another router and changing addresses. For those without the book (which is very good by the way) this is frame on physical interfaces in a hub and spoke configuration. The hub can ping all spokes, and each spoke can ping the hub. However, spokes can not ping each other until the 'frame-relay map ip" statement is added to point to each spoke. Everything can now ping everything else. Now we save the configs and reload. Since map statements have not been added on the spokes to point to the hub (since they were originally learned dynamically) I expect that dynamic inverse arp to be disabled, and there will be no dynamic entries on the spokes for the same protocol and the same dlci. This is not the case in my lab here is the relevant part of the config on one spoke, and the results of 'show frame-relay map' interface Serial1 ip address 192.168.14.2 255.255.255.0 encapsulation frame-relay frame-relay map ip 192.168.14.3 201 frame-relay map ip 192.168.14.4 201 no frame-relay inverse-arp Router2#sho frame-relay map Serial1 (up): ip 192.168.14.1 dlci 201(0xC9,0x3090), dynamic, broadcast,, status defined, active Serial1 (up): ip 192.168.14.3 dlci 201(0xC9,0x3090), static, CISCO, status defined, active Serial1 (up): ip 192.168.14.4 dlci 201(0xC9,0x3090), static, CISCO, status defined, active Can someone explain why this is happening?

Re: Frame Relay Map Help
No, Inverse arp at the hub is still active. Since there is a frame map statement on the spokes, I expect that inverse arp would be disabled for the protocol (IP) and the dlci as Cisco's documentation states. Caslow's book shows that the spoke router would lose the dynamic maps. On the other hand the hub has no idea of the spoke's map statement... and will still send its info down the serial line the spoke router will hear the info and associate the IP with the dlci. This is the only rationalization I have as to why the spoke router still gets the dynamic info.

Re: What ISP do you recommend for BGP?? [7:1295]
Working for one of these providers now (and the other in the past) my 2 cents is that BGP implementations are almost always ugly no matter who you choose. Most sales people who are responsible for filling out your order form have no clue as to what BGP is or does and therefore do not get all of the required info that engineering needs to implement a BGP session between you and the ISP. My advice is that no matter who you choose get a copy of the order form and make sure you fill out all of the requested information relating to BGP yourself . DO NOT RELY ON THE SALESPERSON to do this for you correctly. Once the order is complete ask to have it gone over on a call with the engineering team that is going to implement your connection. Make sure they have everything they need. They may ask for the routes you plan on advertising as well as router configs and information about other BGP sessions you are running with other providers. Lastly, remember, the ISP is not responsible for configuring your router. Many of the folks that request to use BGP instead of static routes are terribly unprepared to configure their equipment properly. If you want to be on the biggest, badest network out there (Qwest just went to a fully OC-192 backbone running on the Juniper M160 platform) you probably dont want to go with AT&T's 100 year old legacy network ;-) Ed Dombrowski ""KY"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I think you may want to stay away from Qwest, ATT seems not too bad > sometimes. > But, IMO, just different extend of pain most of the time for all those big > names, especially if you are a tiny little customer. > > Just my two cents. > > Good Luck > > KY > > > ""BH"" wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hi, > > Does anyone have a recommendation or horror story for best ISP to work > with > > for implementing BGP? > > I am thinking of picking between Worldcom, ATT and Qwest. > > Thanks > > FAQ, list archives, and subscription info: > http://www.groupstudy.com/list/cisco.html > > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=1313&t=1295 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: what does " no logging console" mean? [7:1708]
Will prevent the router from writing logging messages to the console. Usually you want this if you are doing heavy logging to a syslog server and you are doing the config work from the console port. Saves you from seeing all the messages while you are trying to type config commands etc. The logging level determines how many messages you will see and of what type.

Access server configuration [7:2376]
Can anybody post some working configs for a 2509 or 2511. I am going nuts trying to configure a 2509 i just got. I have been using this page as a reference but i am not having much luck. http://www.cisco.com/warp/customer/793/access_dial/comm_server.html. I cant seem to find any other info on the cisco site relating to just setting this thing up plugged into the console ports of my other routers. Currentl;y i have it working on one router (the 1601) but i cant get a second one to work (2521). I cant tell what the difference is at this point. I will post my running configs if anybody can offer some tips. The configs are a bit messy on some of them as these are lab routers and i am studying for my BSCN exam. I posted this to the other 2 cisco newsgroups yesterday but i think my news server sucks. I still dont see my posts 15 hours later Also, the 1601 router when i try to connect gives the message connection refused by remote host but if i hit enter again it connects. The 2521 just gives me the same message but wont connect at all. I would really appreciate any help. I just cant find any info that is useful anywhere. I even drove to the bookstore and looked through about 15 books but didnt find anything more specific then the page i refrenced above. 2509#show run Building configuration...

Re: Cisco IOS Question [7:2545]
You may need to have a CCO ID to access this page but here is the Cisco feature Navigator page. This will allow you to pick a feaure/platform and see what Feature pack it is available in. While this doesn't specifically address your question i have found it to be pretty helpful. This is especially helpful when i do configurations for customers and they have a specific feature that they need. I can then look it up and decide which service pack to add then go to the memory tool to make sure i have enough for the feature set.

Re: WAN Congestion - Cloud technology - Theory vs Reality [7:2645]
Another concept you may want to investigate in regards to Frame Relay and ATM is closed loop architecture and open loop architecture. It has been a while since i have read about the differences but if i remember correctly open loop allows the customer to keep sending traffic and then relies on the customers higher layer applications to manage the congestion control. In closed loop the carrier is aware of the congestion from end to end and will throttle back customer traffic at the edge and use congestion notification backwards and forwards along the path to control congestion. By throttling back the customer trqaffic at the edge it keeps more traffic from getting onto an already congested network and making the problem worse. Some carriers use open some use closed. I am sure my definitions leave something to be desired but i think that is the basic idea. It might pay to do a search at the Frame Relay forumn if you want more info.

Emutel solo ISDN simulator opinions needed [7:2918]
Does anybody have any opinions on the Emutel solo ISDN simulator from Arca technologies. I hear great things about the Teltone but at $2800 for the model that handles both ST and U interfaces i started looking for an alternative. It appears the Emutel Solo can be had for a retail of around $2000 and supports both types of interfaces. If you have experience with this product can you leave a brief review and some pros and cons? Thanks.

Re: Emutel solo ISDN simulator opinions needed [7:2918]
Actually i looked into this option. Total cost of install charges for just the 2 BRI's without any adaptar hardware to go from my ST to U interfaces was $800. This is without any monthly charges for usage. Add an extra few hundred for hardware to connect to the telco circuits and i am over $1000 without usage. When i am done i have nothing but a big bill. If i buy an Emutel or a Teltone unit i can use it for as long as i need it with no concern for usage charges then sell it on Ebay for a very good percentage of the original cost. If you ever see these units on Ebay they sell for 80-90% of original retail. In the long run it will be much cheaper to buy the Simulator then the real service.

Re: Seeking opinions on the following hardware for Lab.. [7:3196]
As you stated you will want a high end switch. I would think you would also want at least one router with a Fast Ethernet interface that supports ISL trunking (like a 2620 ect) coming from the switch. In addition you would probably want something like a 2523 (8 serial, 1 Token, 1 BRI) This will serve as your frame relay switch and a second Token ring interface. Lastly, if this lab is going to be all in one place and the other two people will have access over an always on internet connection (cable modem, dsl etc) you would really save yourself a lot of hassle if you got an access server like a 2509 that has 8 asynch ports for connecting to the console ports of the other routers/switches. I tend to work on my lab from work alot (my lab is at home hanging off a cable modem) and it makes life much easier when you can change ip addresses and shut down interfaces without worrying about losing connectivity to the router you are working on. Another good thing to do is go to the CCbootcamp page and take a look at the physical layout of their CCIE labs. They have 4 set up and it will give you the idea of the complimentary equipment you need.

Re: Cisco Exam Subnetting question! [7:4310]
It appears that a portion of the question may be missing. My best answer would be - there are 32 bits total. 22 bits are for the network portion 2^22 = 4194304 subnets 10 bits are for the host portion 2^10 = 1024-2 or 1022 hosts in each subnet. This dosen't match any of your answers. Mileage may vary based on the missing info. If you said it was a class B address range and you had 22 bit mask, I would say: Class B has 16 network bits. The mask is 22 bits, so we have 6 bits to play with for networks. 2^6 is 64 networks. Beware that according to the Cisco Class meterials, they still say the first and last subnet can not be used - so this leaves 62 usable subnets. We still have 10 host bits, so it is the same as above. Beware of the termonolgy - In my example, we have 16 network bits, 6 subet bits and 10 host bits. The network bits are determined by the address class.

OSPF routing table explanation [7:4448]
Below is a routing table from a scenario i am working on. It is for OSPF over NBMA in Point-to-Point mode over subinterfaces. It is probably an easy explanation but something i would like to be clear on. My hub location is the 2521 which is where this table is from. I have three routers connected to it VIA subinterfaces running through a 2523 acting as the switch. I used 192.168.1.0 /30 for the wan addresses. On my remote 2501 connected VIA Serial0.102 i added loopback interface 1 ip address 192.168.1.33 /27 as i wanted to see how the VLSM address showed up in the route table of the 2521. The table is as follows. 2521#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR Gateway of last resort is not set 192.168.1.0/24 is variably subnetted, 4 subnets, 2 masks O 192.168.1.33/32 [110/1563] via 192.168.1.6, 00:00:17, Serial0.102 C 192.168.1.8/30 is directly connected, Serial0.103 C 192.168.1.12/30 is directly connected, Serial0.104 C 192.168.1.4/30 is directly connected, Serial0.102 2521# My question is why does the address show up as 192.168.1.33/32 instead of /27 as i expected. I have dug around through my books and i understand VLSM but cant find a simple explanation as to why this shows up as a /32 address. Can anybody explain this to me?

Advantages/disadvantages of WS-x5006 module over ws-x5009 [7:6023]
Can anybody offer any insight into the advantages or disadvantages of a ws-x5006 SUP I module (FX uplinks) compared to a ws-x5009 SUP I module (TX uplinks) in a typical CCNP/CCIE lab environment where the CAT5K is probably the only switch or maybe there is one other switch like a 2924 xl. In a single switch environment it doesnt seem like there would be much difference and there seems to be many more CAT5k switches with 5006 modules on ebay. In an environment where you have say a 2924 downstream from the CAT5k wouldnt you just use a 10/100 link from something like a 5213 card? I know this is kind of a basic question but i am just looking for some insight on this issue.

Re: I want to build CCIE lab in my home [7:7853]
Many people use the CCbootcamp lab scenarios to prepare for the CCIE lab. At http://www.ccbootcamp.com/ there are diagrams of the hardware they rent out that will be able to accomodate all their lab exercises. If you look at their hardware layout it will give you a good feel for what is in a well equipped lab. You may not be able to afford all the items they have (Like ATM and an ISDN simulator) but most people that i see that are serious about preparing for the CCIE spring for 7-8 routers and a CAT5000 switch. Some get by with less some have more. It depends on your situation. There is some real good info on the CCbootcamp site on what equipment you will need what books and preperation strategies.

Re: ISDN Simulator [7:8132]
I dont think there is any such thing as an "affordable" ISDN simulator but i got the Emutel Solo and it works like a champ. It has configurable S/T or U interfaces and supports all kinds of switch types. It is comparable to the Teltone ILS 2000 ($2800) and the price direct from Arca technologies is $1995. The only problem is that buying it direct is a HUGE pain in the butt. I eventually bought mine from the supplier that is associated with ccbootcamp.com. It was more then the direct price but saved a lot of time an hassle. They sell for pretty big bucks on Ebay so i figure if after i am done with it i can sell it for 70% of what i payed it isn't so painful. HTH Ed ""Raul F.

On Going Rate for IT Professionals [7:33776]
Guys, Well, maybe I am in the wrong board but just a quick question. What is the current ongoing rates as an independent contractor for IT Help-Desk, NT/2000 Netadmin, Network (Cisco) Support, etc. Given that I live in the Silicon Valley, and about 4 years of experience with all the related certs (besides CCIE).

Re: BGP Synchronization and OSPF External Routes [7:35131]
I don't think this is just OSPF, but rather any protocol that recognized Internal and External Routes. From what I understand, the basic reason is to keep from shooting yourself in the foot. For example, why would you want to advertise addresses that belong to another AS? On Page 135 of "Internet Routing Architectures", Halabi writes, "(In the Cisco implementation, external OSPF routes are automatically blocked from being redistributed into BGP; the administrator has the option of overriding this behavior.)" I haven't tries it, but on page 318, it looks like you simply "match" both types on the redistribution command... router bgp 3 redistribute ospf 10 match external 1 external 2. Also on 318, Halabi states this is for "loop avoidance" in the case the external OSPF information came from BGP. For more info you can look on CCO: http://www.cisco.com/warp/public/104/bgp-ospf-redis.html http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/np1_c /1cprt1/1cbgp.htm Ed "Jeff Hillman" wrote in message news:[EMAIL PROTECTED]... > I have not been able to find any information on Cisco's site on why BGP > synchronization does not recognize OSPF E1 or E2 external routes when > checking the IGP routing table.

Free Cisco Lab This Weekend [7:37718]
Guys, Due to the popular demand, I am offering the free CCIE lab again this weekend. Check out www.router4u.com for login and password, and see it for yourself. It runs on first-come-first-serve basis and everything in the rack besides the RPC unit is available, including CAT5K and ISDN switch. Please do not set the password on any of the router and switch since it may require password recovery process and the RPC isn't working correctly yet. In return, please let me know what do you think that could improve this site. I am trying to get the CAT 3900 sometime this month and that should spice up the rack a bit.

Re: Passed CID [7:12886]
I found that I had already achieved 80-90 % of the study necessary for the CCIE written exam after I completed CCNP and CCDP. My area of study turned to topics related to bridging, DLSW+ and BGP. The materials I used were: Caslow Doyle Halabi OSPF Network Design Solutions EIGRP Design Solutions Giles CCIE Study Guide (very good and in depth discussion of layer 1 & 2 topics) Advanced IP Network Design I borrowed a firend's Exam Cram book and found it to be virtually useless.

Re: Cisco Press Vs Sybex Which Way Forward ===> [7:13243]
I agree with Chuck... I'll take good advice from anywhere I can get it This goes back to : "where go you get your good judgment?" "I get my good judgment from good experience!" "And where do you get your good experience?" "From bad judgment!" I tend to like the Cisco Press books more for the certification series than the others. First, Cisco is putting their name on the books - Granted, Cisco Press is another publishing company and they are out to make money. However I have to believe that when a Cisco Press book says CCNP/CCDP, it follows the actual Cisco course material more closely, at least that is my experience from reading the books then taking the exams. Remember, there are many ways to do something... but there is also the "Cisco way" - not to say that the Cisco way is always right, or even wrong, but when they make a statement in a class, it should be that way for the exam. Like the difference between a pilot and a prototype... I come from an electronics engineering background... I think Cisco has the terms reversed in their texts... But when it comes to the exam... its the Cisco Way. There are many authors out there, of which I am one. I was a contributing author to a book in a CCNP series. My certification doesn't mean that I am an expert, and by no means does my Cisco certification qualify me to teach. The sign of a good author or instructor is how well they are able to present the material... Yes, they have to know the material, and this is through experience. However, my experience doesn't provide me with any more insight to the Cisco exams than the person reading the book other than I have taken the exam and passed. I make statements relating to the exam blueprint, and those statements are related to my education and my experience.... keeping in mind, that my answer may not be the Cisco answer - Ed Edward A.

Re: ccna challenge question [7:13565]
The key in the question is the word "classful". This is a Class B address with a 16 bit classful mask. I would have to say the correct answer would be 'C' 172.18.255.255.

Re: Cable modems & 2501s?? [7:13626]
wow... looks like everyone has their own opinion on this. Yes, a 2501 can do inside and outside NAT on the same interface... this would be one solution. Another would be to use primary and secondary addresses on the interface. For both of there, you would need a hub attached to the cable modem and the router. There are many other options out there. Personally I use a LinkSys Cable/DSL router. This has an outside address, and then NATs the inside addresses. It will also do basic PAT as well... I can telent to my lab from the Internet and even better, I can initiate connections, pings, etc from the router in my lab to the Internet.

Re: ccna challenge question [7:13565]
Everyone has some good ideas on this... and one of the replies made me rethink my previous answer Look at it from the aspect of the ROUTER... assuming that this is implemented on a router. An interface with the address of 172.18.2.0 and a mask of 255.255.254.0 will send directed broadcasts to 172.18.3.255. Answer B is correct. However the above router sends a RIP version 1 update (which is classless) to router B. Router B gets the router 172.18.2.0 and no mask information. It assumes a classful boundary. ( I know, there are other rules that affect the advertisement and receipt of the route) Router B will then send directed broadcasts to 172.18.255.255. I think everyone would agree that the question is poorly worded... If I came across the question I would still select 'C' as my answer, 172.18.255.255. My clue in the question is 'using classful assumptions' Ed Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=13767&t=13565 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
