Frame-Relay Question...
Hello: Excuse me if this kind of question doesn't belong here. I am in the process of preparing for CCNA and reading Wendell Odom book (BTW, any wanna be CCNA read this one regardless what others have to say). I am in WAN section right now. In his example of partially meshed network ( routers A B C D, A connects to B C D and A is only the router connected by B C D). I understand why we need subinterfaces on router A. But why we he has subinterface set on routers B C D? Is it because of setup consistency or what is the catch?

Fatkid lab 212 question
I have a question regarding Fatkid lab #212 "IP Routing with EIGRP". In the solution, they show R2 with a floating static as follows: ip route 200.100.100.0 255.255.255.248 212.1.22.33 200 which basically encompasses the loopback address of R3. Why did they do it this way? Wouldn't it be more appropriate to have done: ip route 0.0.0.0 0.0.0.0 212.1.22.33 200 I mean, afterall, once R2's serial link goes down, it has no way to get anywhere, and wherever it wants to go, should trigger the dial backup imho.

Re: Broadcast Suppression!!
Hi Jeongwoo, It is not as simple as that. Do you want to use hardware suppression or software? Hardware is base on % of bandwidth and software is base on per packet. I personally prefer hardware as it will continue to forward unicast traffic and block multicast/broadcast traffic. Hardware base is only available on selected models (enterprise class). Software will shut down the port if amount of multicast/broadcast traffic reach the threshold. Another thing to remember is the router, most routing protocol use multicast to pass information. If you set a low threshold, the link will keep flapping. Does the customer use streaming video, multimedia server or any other application that use multicast? Have a look at all these before you implement the suppression. Explain the impact to the customer. Ask the customer the reason for enabling broadcast suppression. The customer may have heard of it and don't realize what is does.

Re: OSPF and static routes
Where is Howard when we need him! &;-) Seriously, if he were to answer, I'm sure he would say that your understanding is right on. Routing protocols are supposed to be ships in the night. So a static route, which is a different routing protocol (or non-routing protocol), shouldn't affect OSPF's LSAs. But it does in your case. It could be a bug, as you say. Do you have a lab where you could try to recreate the problem? I wish I had more time and I would try it Would a workaround be to give the static route a higher administrative distance? Maybe if you make it a "floating static route" by giving it an admin distance higher than OSPF, it won't get in the way of Router B's OSPF's LSA over to Router C. Not sure if that would meet your goals, though. Priscilla At 01:15 PM 11/8/00, you wrote: >This is a resend - apologies if it appears twice.

Re: OSPF and static routes
This is a resend - apologies if it appears twice. Or indeed three times. Mark, thanks for your comments. A couple of points that I didn't make clear in the first email... Although the static route overrides the OSPF route on RTB, RTB does know about the 50.0.0.0 network from OSPF as well - it shows up with 'show ip ospf da su'. So there is an LSA for that network in the OSPF table on RTB. My understanding, which you seem to confirm with your point 2, is that routing protocols (in this case, OSPF and static routes) work independantly of one another, and that barring redistribution, OSPF will not have any knowledge of the existence of the static route. If this is the case, then regardless of the layout of my routers or any other complexities, adding a static route should make no difference to what LSAs are distributed by OSPF, and so there should be no difference in what RTC gets. However, these routers seem to think otherwise :-) Unfortunately I can't bung on a debug of OSPF to see exactly what LSAs are being transmitted - I don't think the routers would cope very well and I wouldn't be very popular if I brought them down unexpectedly. If somebody could confirm or deny my basic understanding of routing protocol behaviour, it would be much appreciated, because if I'm wrong I have a lot of studying to catch up on... RTB is actually an MSM with lots of qualifiers in the IOS version, and RTC runs a completely different major version of IOS, so it wouldn't surprise me too much if this is the result of a bug.

I may be false or short on some of this so somebody will correct me if I am wrong. 1.) The reason that router C is not getting anything from B (50.0.0.0) is because, and you said it yourself, it is not redistributed on that device. A static route has a lower admin dist. so it will be chosen. Therefor, the summary that would be normally sent to router C via ospf is over-riden by the static route which you have to manually place on router C. That's why when you take out the static route, router C gets the route back. OSPF see's a change in it's tables and recalculates. It see's that there now is a route to 50.0.0.0 via ospf and that there is no other route there with a lower admin dist. so it is chosen and propogated. I could be wrong or incomplete on this... 2.) You spoke of ships-in-the-night. Actually, I just read up on that in terms of EIGRP. In EIGRP there is support for 3 protocols: IP, IPX, and Appletalk. Inside of the EIGRP process, when it is running, these 3 protocols (if all used) don't have anything to do with eachother. They are kind of oblivious to each others operations and are in their own, lets say, platforms. This is what ships-in-the-night means. None of them are dependant on each other and they don't even care if the others exist. Hence the term "ships-in-the-night". I hope I helped with some of your questions.

Re: Frame relay problem
You can do 'show frame lmi' on your router and compare 'Num Status Enq. Sent' with 'Num Status Enq. Rcvd'. They should be the same. If they don't match, clear your counters and check again, and check after your problem occurs. Another useful command to check lmi is 'debug frame lmi'. This is a fairly safe debug, unless you have squillions of PVCs. Having said that, don't blame me if turning it on makes your network fall over :-) You can check how often you receive lmi from the switch (make sure it matches your keepalive, which is 10 seconds by default), and every minute (this might vary depending on switch type, dunno) you should see a list of PVCs known by the switch and their status (0x0 is inactive, 0x2 is active if I recall correctly). Having said that, I suspect it's not an LMI problem. If the LMI wasn't received at all, I *think* you would see the PVC showing up as deleted (the switch doesn't know about it), not inactive (the switch knows about it and knows it's down). Do PVCs on all ten routers go down at the same time? If so, I'd seriously yell at your telco.

RE: CCIE Design Reading List
I was just recommending this book to a friend today for the exact same reason. In other books you may learn how things are done, but Doyle's book you learn WHY the protocols work the way they do. Chapter 4, Dynamic Routing Protocols, cleared up some grey areas and a misconception that I had. Instead of dreading reading about routing protocols like I used to (because the information seemed like lots of unrelated facts, or bits and pieces of the big picture) I now look forward to it because I have a better understanding of the protocols. In this chapter, Doyle gives a very clear and straightforward (read plain English) explanation of the SPF algorithm. It's all so clear to me now.

Re: Appletalk PHASE I and II
Did you try the Cisco AppleTalk Configuration guide here: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/atipx_c/2cdapple.htm Also, see my white paper on AppleTalk at www.certificationzone.com. Apple and various third parties (including Cisco) started shipping AppleTalk Phase 2-compatible products in 1989. You shouldn't have to know anything about AppleTalk Phase 1 anymore, but here are a few comments anyway. The main enhancement that Apple added in Phase 2 is support for more than 254 nodes per network. Because of interoperability concerns, it was deemed impractical to change the size of the 16-bit network number field. So, with Phase 2, Apple supports extended networks. On an extended network, the administrator can assign a range of network numbers to a physical network. Cisco calls the range the "cable range." For example, you can assign the cable range 10-12 to a single physical network. That network can then support 3 * 253 nodes. AppleTalk Phase 2 disallows node numbers 0, 254, and 255: 0 means a router on the network 254 is reserved for future use (it was allowed in Phase 1) 255 means all nodes (broadcast) With Phase 2, Apple also started supporting multiple zones per network. Neither the multiple-zones per-network or the non-unary cable range feature really caught on. About the time Apple started supporting larger networks, people started getting concerned about broadcast traffic, and the migration to IP began. By the way, in AppleTalk terminology, "network" means a set of nodes connected via cables (or wireless technologies), hubs, switches, or bridges. An AppleTalk network is bounded by a router, must like an IP subnet. All nodes in an AppleTalk network are in the same broadcast domain. So having more than 254 nodes isn't really a good thing, anyway. Phase 2 does have a couple other features: They started using 802.3/802.2/SNAP packets on Ethernet instead of Ethernet Version 2. They added support for the Best Router Forwarding Algorithm which causes end stations to be smarter about which router they pick. And there were a few other features that are totally irrelevant and don't come to mind anymore. &;-) Priscilla At 03:14 PM 11/7/00, Martinez, Carlos wrote: >Hello All, >does anybody know where I can get some info on the differences between >Appletalk Phase I and II > > thanks > >_ >FAQ, list archives, and subscription info: >http://www.groupstudy.com/list/cisco.html >Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] Priscilla Oppenheimer http://www.priscilla.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

The 3810 is even more expensive. Thats what I am thinking fxo/fxs. I can't really agree with you though that a 3810 is "expensive"one closed today on ebay for $1126 and had a nice assortment of fxs/fxo ports to boot: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=487396267&ed=973628747 these aren't rare on ebay or the secondary market either...like I said $1500 looks like it can get something decent. > > Also remember, You need access to 2 voice routers to make it useful. nod, thats why I was thinking 2620/2610. the 2620 will get you fast ethernet as well.

Re: Frame relay problem
This sounds like your router misses LMI status messages every once and a while. This could mean a timer problem or the serial interface could be too busy to process them correctly. My guess is the timer problem, check with the carrier (or use a WAN sniffer) to see how often LMI status messages are being sent from the frame switch to your router, then make sure the defaults or the config on your router matches.

RE: Frame relay problem
FR ckts. can drop generally either due to provider switch problem or due to line problem. If you got a CSU/FRAD, check the line performance parameters. First look for stats. to see any errors, specially SES/BES or UAS. Some CSU/DSU provides also status on the errors like Yellow/Red alarm etc. Also check Frame relay parameters like Frame reliability errors and lmi disconnects to isolate whether this is a frame relay issue. From a practical point of view, run a continious ping with 1500 bytes to see whether packets drops but your problem more seem to be a LEC issue or FR switch. Once a ckt. drops it takes exactly 1 minute for FR ckt. to come back up. Hope this helps.

Re: CCIE Design Reading List
Their book list for CCIE design is pretty bizarre. The most bizarre thing is that they recommend "Designing Campus Networks." Read the Amazon reviews before you buy that clunker. (It's not the same as "Designing Cisco Networks.") In answer to your actual question, you would be missing out on a great book if you don't read Doyle's "Routing TCP/IP." It is not focused only on configuration. It is focused on explaining how the routing protocols really work. You should read it for all certs, I think.

Re: DNS Problem
Thanks for the info. I was just getting sick of all the misinformation so I over-simplified a bit and optimized for the most usual case. I was glad to get your response, though, since you obviously have the Authoritative Answer bit set! &;-) So, why would a DNS query generate a response that would be larger than 500 bytes, though?? I am aware of the Truncation bit in the DNS header, but have never seen it set. Just trying to learn. Thanks.

Re: IP RIP V.1 in the LAB ?
Thanx for the input, Unfortunately the configs are 120 miles away. I only really get a chance to play at the weekends when I'm back home. But there is really nothing fancy in the configs. When I cut the link TOP->RIGHT I waited for the route to get flushed out the table i.e 280 secs (I think) But the route from LEFT is definitely being advertised to RIGHT according to the Sniffer and being rejected by RIGHT. (Split Horizon Possibly) TOP Learned two routes to Network LEFT->RIGHT via LEFT and RIGHT Respectively and load balanced them. I would have thought this to be the case with LEFT and RIGHT also since RIP only has hop count to work with. Split Horizon thoughts RIGHT learned the TOP->LEFT network via TOP. RIGHT didn't learn the TOP->LEFT Network via LEFT ? and didn't load balance. When I broke the link I used shutdown. Maybe I should have physically uncoupled the link ? Although the route did get flushed. So RIGHT should have learned a new route to TOP->LEFT via LEFT. O, I'm confused. If there is no progress I'll try to post the configs. But they are so straight forward its untrue. e.g before this LAB the Ethernet Seg was split, so that I just had a linear network and this worked perfectly. Obviously when I triangulated it, I put both Ethernet interfaces on the same network. But that was about it really.

Voice isn't really expensive. 2610's empty are about $1000. Add a nm-2v and a few hundred dollars in vic's and you are set. It looks to me that with a 2610, you can get a decent voice router with some fxs/fxo action going for $1500. Times two of course for doing scenerios. $3k I can live with. What I would really like is a 2610 and a 2620, that way I pick up fastethernet cheap as well for vlan's etc. I think I can get a 2610 and 2620 for $3500 or so (package)... ATM is whats expensive.

Re: Voice for lab
I have a 3810, it is NOT cheap. The 2600 series is modular, so more useful in the long run. The 2600 requires both a voice processor card ($750-1200, 1 or 2 VIC support) and the personality card (VIC - $300 new) to do voice. The least expensive way to go is get a 1750. The 1750 uses the same personality (VIC = FXS, E&M, FXO) cards as the 2600 and you do not need the extra (expensive) voice processor card like the 2600. You can get a new 1750 for about $1600, add $300 for a FXS and you are ready to go, with VPN to boot! Used, you can find one for about $1000.00 with voice, or buy a used 1750 alone for $500-$800 and spend $300 for the new voice card (VIC). The VICs have 2 ports per card. The 1750 has 3 card slots, 1 is dedicated to VIC use. the other 2 can be other WAN cards or VICs. You may be able to get a used 2600 with voice for $1500.00 (Usually a FXO, the FXS is better for home use since you can plug a regular phone directly into it) . The 3810 is even more expensive. Also remember, You need access to 2 voice routers to make it useful.

Re: IP RIP V.1 in the LAB ?
Hi all, another $.02, This doesn't look like a topology that Split horizon would be a factor. I'd suspect (given the total absence of information) that this is a classful issue. RIP from "Right" would send a null update, if there was nothing to send, ie. the other router, "Left", knows how to reach all of the "classful" networks. Left sent its update first, so, Right just sends null updates. Rodgers Moore "Phil Barker" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]... > Hi Gang, >Three Routers in a triangle.

A CCIE Written Study Group and CCIE Lab Study Group for members that have passed the Qualification exam, with members helping each other get to the next level, ie. members who have passed the Lab spend some time with the CCIE Written Group in coaching them, and maybe a CCIE in Cincinnati kind enough to coach the CCIE Lab Study Group. The idea I am getting to is that it has to be a consistent regular meeting class. All comments and input appreciated, and if there is a CCIE in Cincinnati that is willing to help us, coach us and proctor us as we prepare for the Lab, please let us know. _ 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] _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Voice for lab
I am wanting to add voice to my lab. I was thinking a cheap way to do with was some 26xx routers and voice cards. What about the MC3810 though? Does that use the same commands/configuration as any other FXO/FXS etc? I mean, can I essentailly use it as good as a 2610 for example as far as doing voice scenerios?

RE: ospf process id / AS??
The concept of an Autonomous System is carried in the AREA(S) used by OSPF. There are 4 things which enable OSPF routers to become adjacent in the same area. Area Identification Authentication Hello and Dead Intervals Stub Area Flag However, the AS may consist of several areas arranged in a hierachy with Area 0 at the top. The AS can seen as a group of one or more areas under the same administration. The router process-id only identifies a particular separate algorithm of OSPF. There can be more than one OSPF process running on the same routers in the same area. Hope it helps.

Hi All, We are having Fragments Timed Out and Fragments Dropped on our network with the following layout: TANDEM(main site, NIC FastEthernet)CAT5500(main site)---WAN(T3)--- CAT5000(backup site)TANDEM(backup site, NIC FastEther) >From time to time TANDEM people get Fragments dropped and Fragment Timed Out on backup site . If I lock at the SWITCHES and RSM I am not seeing any collisions (no errors) nor trims or packet missed. The application use udp protocol. I contacted CISCO but till they don't have any clue , only they keep asking me to use a sniffer to capture the traffic and send it to them, nothing wrong on that but since this problem ocurr rondomly some time even sunday night at 3:00 am when is not to much traffic is hard to capture traffic when had ocurred. Has anyone seeing this and how can I fix it? Thank you all for your help in advance. Mike _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

BGP - maximum-list
Has anyone used the maximum-prefix command on a cisco running BGP? It is supposed to keep a neighbor from going crazy and swamping your router with too many routes by limiting the number of routes that can be learned by the router. What would be a good number to set that at to allow a full BGP table, plus growth, and still protect the router.

This is kind of long, but here is a column I wrote on the topic a few months ago: I'd also recommend getting a copy of "Wide-Area Data Network Performance Engineering" by Robert G. Cole, Ravi Ramaswamy, which directly addresses this topic. Irwin -- The bandwidth size that is required for any given connection is a function of the following three factors, number of users, requirements of specific applications, and how the application is used. For example, a site with five users that all access a highly interactive application for twelve hours per day may require more bandwidth than a site in which a dozen users sporadically access a client-server application in which most of the processing is performed by the remote server. In addition, another concern in the bandwidth selection process is delay. Certain applications such as voice and video may require a low level of delay (latency) as well as a low variability in delay (jitter). These requirements may add significant complexity to the design process. The first step in sizing bandwidth is to determine the requirements for the specific applications that will be deployed. During this step, a sniffer is useful in tracing application sessions to determine the average packet size and the average number of packets for a given transaction. Once you have these values, the next step is to factor in the number of users, the required latency, and the amount of time that typically exists between transactions. Once you have obtained these values, you can use the following formula (created by Ravi Ramaswamy of AT&T Solutions) to determine bandwidth requirements: 8 x N x K x M / (K x P + T) Where: N = number of active users at a location (the number of users that will simultaneously use an application) T = User think time (how much time typically exists between inquiries) K = number of packets per transaction in any given direction M = number of bytes per packet in any one direction P = one-way network latency Note that this calculation must be performed for both directions of the connection. The required bandwidth is then the maximum bandwidth estimated by this formula (unless you are deploying a technology such as Frame Relay which allows for different bandwidth allocations for each direction of the connection). Note also that this formula only applies to client-server type applications in which there is a substantial amount of two-way traffic. For additional information on bandwidth sizing, please see "Optimizing Client-Server Application Performance on the WAN" in the November 1999 issue of "Network Magazine." _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Name queries from clients can be TCP if the initial response is too large. Initially, the UDP query will generate a UDP reply. If the response is greater than about 500 bytes, it will be truncated and a truncate flag will be set. Then the client (or name server) is suppose to retry with TCP. This is the behavior for a BIND 8.x name server... I believe it's the same with BIND 9.0.0. Therefore, TCP (as well as UDP) is needed for name queries. The name queries primarily use UDP, but you'll still use TCP in certain cases. You need it open for zone transfers anyway.

Imagine this: Top LeftRight TOP learns LEFT from LEFT. RIGHT learns TOP from TOP. RIGHT learns LEFT from TOP. RIGHT announces routes about TOP and LEFT to LEFT!!! LEFT will not announce routes about either TOP or LEFT out its Left/Right interface, since it heard about it from there. that might not be the *exact* sequence of the loop you are seeing, but "supressing null route" is a split horizon error. I have seen this for example when configuring a static SAP on the same interface you wish to announce it on.split horizon will kick in, and you will see "supressing null route". You have created a loop by design above. Split horizon's job is to break it at some point, which its done between Left and Right.

Re: Subinterface question
Jeff McCoy, I agree the administrative distance is 0 for all directly connected interfaces when using any routing protocol, but as the first entry says from I think Jeff Walzer routing will first look for the most specific entry- most contiguous bits specified left to right.

On Tue, 7 Nov 2000, Jeff McCoy wrote: > If the process id is defined as 200 in the command: > > router ospf 200 > > and this is not the AS, then where is the AS defined? OSPF does not use the notion of an AS for its routing. With IGRP and EIGRP, processes on different routers must use the same AS, or else information will not be exchanged. With OSPF, this is not the case, any router within its reach running ospf can essentially become a neighbor, and possibly adjacent. To restrict this, you would use OSPF authentication, so that only routers you wanted would talk to eachother...you could even set up multiple seperate OSPF clusters to act like EIGRP "AS's". The OSPF process id's only real practical use would be to allow you to run multiple seperate OSPF processes on a single router, which I doubt you would want to do.
