RE: CCIE LAB PREP STRATEGIES [7:15046]
Hi, I will go for the CCIE written next week. I think I will go for the lab in Dec, 2001. Nice to hear many of u just pass the lab. Is it include ATM, VoIP, LANE, Token ring, DLW+, RSRB and SRB, etc...what is their weight. It's good if all of you give me some advice. Actually I tried to prepare the written and practical test together. Behind me is most of the CCIE CISCO press and Carlow. I have taken CCNP, ATM and VoIP specialization exam. The equipment with me is 2 x C2522 and 3 x C2503. There is Token Ring and ISDN available. I am planning to apply a BRI connection at home for all the ISDN testing. It is not so expensive about US$70/month in HongKong. Not sure how much in US. I can't available the Catalyst set-based switch. Is virtual lab help?! Good to share ideas with you guys. Thanks.

Hi, So do I, I passed last week, and booked the lab on Feb. I am currently using ALL in one 1st edition, and behind me are Caslow's 2nd edition and Cisco press Lan switching. I've equipped with 4 router, ISDN demo and 1 set base switch. ATM, Voice and lightstream I cannot afford unless I've win a mark six tomorrow. I'll try online remote rack on this. I am totally no hands on for Token ring part, I don't even now how to connect them : ( , can anybody advice a place or link for me to set up a lab base token ring network? Two of my routes has token ring interface, 1 MAU, 1 Xircom pcmcia card and 1 IBM 4/16. 2 x db9-rj45 and 2 x db9-mau cables. Furthermore, after those book and lab, I'll try bootcamp and most of the Cisco press CCIE development books, I'll keep the Cisco Doc cd in my cd-rom.

Re: RE: Subject: EIGRP's interpretation of NBMA and "disabling [7:15066]
Au contraire. I never actually said that routing was established or neighbor relationships were formed. Quite the opposite was true. I only commented on the protocol behavior as it involved EIGRP timers (5 seconds versus one minute). I had a classic hub and spoke. My hub was a 2511 (just because:-) and the spokes were respectively a 2503, 2520 and a 2522. The cloud was provided very nicely by a 2523.

Re: a question for VPN Design experts [7:15061]
Minor problem. Most routing protocols, via IPSec, have to run over a GRE tunnel. Configuring this on the spokes is easy. Configuring this on the Hub is a little more difficult, since you don't know the destination IP address. Although, you might be able to configure NHRP in order to overcome this. This would require a lot of lab-time to confirm functionality. Another option is to configure the Spokes with NAT/PAT over the IPSec tunnel. Then the Sites connecting to the Core, are acting as clients rather then sites. Minor issue, you can no longer push out updates to systems at the remote sites. You'll need to configure systems at the remote sites to pull changes from the central site.

Re: Advice : CCIE written (R/S) [7:15005]
Chuck is right on the money. I used nearly the same strategy for studying but did not spend enough time on the Token Ring papers. Passed anyway but could have been a little sharper on those papers. For practice tests I used Boson #1 and #2 from www.boson.com If you have taken the CID test, that is also a good way to guage if you are ready for the CCIE written.

CCIE LAB PREP STRATEGIES [7:15046]
Hi all, I passed my CCIE written last week and have the lab exam scheduled for April of 2002.:-( Too much time . I would like to invite advice for a systematic way to tackle the CCIE lab exam including the following areas : 1) What is the exact kinds of equipment required to set up a practice lab ? 2) How much is the extent of Voice and ATM in the lab exam ? 3) What books should I refer to for the lab exam ? 4) I am trying to do the All-in-one CCIE lab study guide and then I will try to do the mentorlabs virtual labs and then probably the ccbootcamp labs .How is this strategy ? 5) How good is Caslow's ECP1 course ? 6) Will taking the CID course help for the lab exam ? I will be glad if someone can help me with the above questions ? Thanks a lot in advance ...

solution to enable secret problem with 12.2-3 [7:15054]
Apparently there is a bug in at least this version of code, maybe more. You can not use the short cut "en secret" or "en password" to change the passwords. It must be spelled out completely. I sent this to TAC as well. They said they had been getting reports from other commands acting the same way. -Patrick Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=15054&t=15054 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Converging the spanning tree can take a long time. In addition, traffic flow may not be optimized. The selection of the root bridge and which interfaces are blocking might not be optimized for all the applications and devices in the large, switched network. With per-VLAN spanning tree, each VLAN becomes a single spanning tree with its own root bridge and own set of blocked ports. This way you can optimize traffic flow and reduce the amount of work to converge to a spanning tree. It's somewhat analogous to dividing a routed network into areas or autonomous systems. Also, at least with Catalyst 1900 switches, if you allow all VLANs to travel across both trunks, you will have a loop. If you don't configure per-VLAN spanning tree, you will have a broken network.

Your method sounds correct. I would lean toward the culprit being in the
IOS. We use EIGRP exclusively on one contract I'm working & I do from time
to time find EIGRP to EIGRP compatibility issues (along with memory leaks).
If you are not exercising Voice ("T" stuff), I have found 11.2(18),
11.3(11a), 11.3(22a), & 12.0(8) very stable GR's when dealing with EIGRP.
Not sure I have helped...

Anyone running this code yet? I can't set an enable or an enable secret for some reason on a router running this version. All the other routers on our network are 12.1x.

RE: Restrictions on Protocol level in Cisco Pix Firewall [7:15045]
Does cisco allow for packet filtering? I know with 3com, I have done something similar to this at the router level. Put a sniffer on the wire, grab the hex information for any command that you want to block and filter based on that hex value. be careful though, this method is not protocol specifc, and it only works with clear text that always has the same hex value. SO, with that being said, if you have multiple devices on the other side of the router that have similar commands, or even two ftp servers, this will cause issues. Of course, this also is totally dependent on cisco's abillity to filter on payload, rather than network info. -Patrick >>> "Kent Hundley" 08/06/01 01:16PM >>> The PIX has some limited ability to look at the application layer traffic, but not much.

Re: Redistribute OSPF -> EIGRP with distribute-list [7:15031]
Your method sounds correct. I would lean toward the culprit being in the
IOS. We use EIGRP exclusively on one contract I'm working & I do from time
to time find EIGRP to EIGRP compatibility issues (along with memory leaks).
If you are not exercising Voice ("T" stuff), I have found 11.2(18),
11.3(11a), 11.3(22a), & 12.0(8) very stable GR's when dealing with EIGRP.
Not sure I have helped...

Redistribute OSPF -> EIGRP with distribute-list [7:15031]
Hello, I was following some examples in my BSCN study guide, but it didn't do as it should (I think). With three routers, A & B in an EIGRP AS and A & C in an OSPF AS. Router C has two loopback interfaces. [RouterB]---eigrp---[RouterA]---ospf---[RouterC]=Two Loopback Interfaces I did a redistribute on Router A from OSPF to EIGRP, and I could now see Router C's two loopback networks on Router B as "D EX". So far so good. Now, I did a distribute-list on Router A to deny one of the loopback networks to be distributed to the EIGRP AS. And I waited, and I waited, and I waited, but the two networks kept being shown on Router B. The default hold-down time should be 15 seconds, since the connection was 64 kbps, but still after 10 minutes, both network showed up. After I on Router A removed the redistribution and added it again, it finally only showed the one (permitted) loopback network address in my routing table on Router B. This weird problem occured again when removing the distribute-list. The routing table on Router B did not show the other loopback network from Router C until I had removed redistribution and added it again on Router A.

RE: Friday Funnie #2, Couldn't let this one go by!! [7:14809]
That's what I meant Howard. I think I left out a few words as I do that most of the time. I think much quicker than I type. My understanding of this: All computer machines were decimal[base10] until the 40's. Atanasoff was the original one who suggested binary to be used instead of base10 to correct the computational probems that existed in measuring current/voltage. In those days with base10, one was a little current, two was a little more, three a little more than that and so on and so on. It was not a very good way to be accurate and was met with many failures. With the induction of binary for current measureage, it became easy and computers were on their way to being a successful marketing venture. One was on, zero was off. Very simple. But the original idea of the binary counting concept started with Ada. Not in the computer sense, but in a general sense of numbers. Or at least that what I have read.

RE: RE: Subject: EIGRP's interpretation of NBMA and "disabling [7:15029]
(E)IGRP ( and OSPF for that matter ) always use the multicast address for their operations. the layer 3 multicast address is independent of the way in which the layer two broadcast or multicast are handled. I'll admit that I get a bit confused on the specifics of the operations. my current understanding, pen to correction, is that with the "broadcast" parameter, frame relay replicates the packets and automatically sends them to all defined end points. without the "broadcast" parameter, other things have to happen, such as layer 3 neighbor statements, which in turn define which PVC the messages go over.

RE: OSPF Link State [7:15006]
there are two parts to this. how does OSPF recognize a link failure if that link is a locally attached interface or media? what if the failure occurs on the remote side? a local interface or local media failure is immediately reported by the IOS to the routing protocol. no hellos are involved. if the failure is on the remote side, how would the router know. so the routing protocol would rely on the hellos. this would be true for all routing protocols.

Re: eigrp:null returned from malloc'ing dual-peertype [7:15021]
Eric, Top of my head. Malloc is a 'C' function that allocates memory on the fly and it has failed to do so. I expect you have found a bug in some old eigrp code as the latest version 11.3 and up tend to be more stable. What version of IOS did this occur on. Check Cisco's website for bugs and caveats for the version you are using for EIGRP. Check the next version also for bug fixes in EIGRP. HTH, Phil. --- Eric ding wrote: > what does this messgae mean?

RE: Advice : CCIE written (R/S) [7:15005]
In my particular case, this is what worked for me: Books: Jeff Doyle vol 1, Caslow, the Exam Cram CCIE prep book. I read Perlman, but other than the first couple of chapters, I am of the opinion there are better ways to spend one's time. Papers: there are two token ring RIF papers available for free, one in on the groupstudy web site. the other is at ccprep. both are excellent and should be covered in depth. Certification Zone - I bought a 6 month subscription and read as many of the white papers as I could download. I took the monthly tests and reviewed them thoroughly ( disclaimer - I occasionally am compensated for work at cert zone ) I took a weeks vacation prior to my written, and spent my final days: half with retaking the cert zone tests ( I bought the CD ) and reviewing. and the other half cramming with the exam cram book. note that the OSPF chapter sucks, the token ring chapter contains a few errors which you will recognize if you studied the other papers, but there is a chapter on the config register settings that is worth reviewing. IMHO, the CCIE written exam I saw bears quite a resemblance to the CID exam. best wishes Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Thompson, Robert D Sent: Monday, August 06, 2001 4:15 AM To: [EMAIL PROTECTED] Subject: Advice : CCIE written (R/S) [7:15005] HI All, Could any of you please advise me on anything I should concentrate my efforts on for the exam, not breaking your non disclosure with Cisco.

RE: help in BGP [7:14954]
A quick thought here. You are correct in saying that the network statement is a trigger used to inject routes into the BGP process. However, it really has nothing to do with IBGP specifically nor does it in any way allow intra AS routing to occur. Routing within the AS will always be the domain of the IGP. I'm not sure if this was the point you were making or not. *** REPLY SEPARATOR *** On 8/5/2001 at 10:33 PM Andrew Fernandez wrote: >The NETWORK command in the Router BGP configuration mode is to inject >local >internal routes learned via an (IGP) Interior Gateway Protocal Routing >protocal i.e. OSPF,EIGRP... into its BGP routing table.

RE: FR ON ISDN [7:15010]
you could "maybe" tunnel frame relay across an ISDN link. After all, you can tunnel frame relay across ethernet. there are links on CCO showing how to do it. Check the frame relay configuration guides. if you could get this working, be aware that the frame keepalives are spaced at 10 seconds. your ISDN link would never drop. and I really wonder why anyone would want to do this. dial backup and on demand routing are different than permanent WAN links. there is an ISDN DDR configuration guide on CCO as well.

RE: BGP cant ping [7:14939]
My guess is that you are pinging router 5 out of router 2's ebgp interface, and router 5 does not have a return route for that network. Have you tried extended ping from router 2 using its ibgp interface as the source address? Generally, you only advertise the ebgp network if you don't want to use neighbor next-hop-self command (for ibgp peers).

RE: CCIE Communicatoins and Services [7:14800]
Hi, Yes, Michael is right. I e-mailed the CCIE team regarding the lab for the C&S exams and the rack will essentially be like the rack for the R&S exam. Although, the lab itself will concentrate more on IP based technologies as apposed to things like AppleTalk, DLSw, etc. It will cover more on VPNs, MPLS, Multicast, etc. I am also interested in pursuing the C&S IE in Wireless.

Re: BGP cant ping [7:14939]
Andrew, Thanks for the information.. but i just want to know if the network command is to be given on EBGP link OK i will try to illistrate the problem 2501(1)---i2501(2)-e2501(3)-e2501(4)---i2501(5) i = IBGP e= EBGP now i have configured the internal network with suitable IGP and IBGP (all the internal rotuer are running IBGP). I tried to ping 2501(5) from 2501(2) it dont ping even 2501(2) have route to 2501(5) in IGP table , but when i tried to ping the 2501(5) router from 2501(1) it pings , it also have IGP router to 2501(5). Then i give a network command in BGP of 2501(2) for the EBGP link then i ping . and it pings the 2501(5) router . i was wondering if we have to give the network command for the EBGP links. -Mamoor "Ahmed Mamoor Amimi" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hi folks... > I have made a senerio in which my network 192.168.1.0 is reach > to me by 3 AS-PATH , and this entry (192.168.1.0) is also installed in my > IGP rouing table but i cant ping anyone on the 192.168.1.0. here is the SHOW > IP BGP > > 2521#sh ip bgp > BGP table version is 10, local router ID is 192.168.9.1 > Status codes: s suppressed, d damped, h history, * valid, > best, i - > internal > Origin codes: i - IGP, e - EGP, ? - incomplete > >Network Next HopMetric LocPrf Weight Path > * 192.168.1.0 192.168.4.1 0 400 200 100 i > *> 192.168.5.2 0 200 100 i > * 192.168.3.0 192.168.5.2 0 200 400 i > *> 192.168.4.1 0 0 400 i > *> 192.168.8.0 0.0.0.0 0 32768 i > *> 192.168.9.0 0.0.0.0 0 32768 i > * 192.168.10.0 192.168.4.1 0 400 200 i > *> 192.168.5.2 0 0 200 i > 2521# > > can anyone have the idea why i can ping 192.168.1.0 network. > I have tried NO SYNC and NEXT HOP but it didn't help. > > -Mamoor Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=15011&t=14939 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Border router as route reflector? [7:14762]
This problem has nothing to do with Route Reflection and is simply the typical behavior for IBGP. Next_Hop attributes are not changed throughout the AS. Your indication of the two methods of handling next hop resolution are accurate, and which you use tends to be a point of preference. I find that most will use the next_hop_self knob however as it does reduce the size of the link state database, and also gives you a Next_Hop address that is more usable to other protocols such as MPLS should you decide to use them in the future.

Assymetric link for customer [7:15012]
Dear sir, Is there any way to control the Bandwidth to the customer for Tx and Rx, i mean if customer wants Tx 64kbps and Rx is 512kbps and this should control the bandwidth for a particular link. I am using both site cisco router and HDLC encap, the local loop remains same ie 512kbps only i have to control the bandwidth on my router without help of extra hardware for Tx and Rx. I am anxiously waiting for reply from any group members.

FR ON ISDN [7:15010]
Dear ALL Can any one help me in knowing how does one configure Frame relay on ISDN. The picture is someting like this : router1(BRI)(BRI)router2(Serial)-FR Switch. Now there are 2 pvc from router 2 to fr switch , dlci 10 for the router 2 itself & the dlci 11 for the bri port for router1. Now the Router2 is swicthing dlci 11 from the serail port to bri port itself.When ever router 1 dials it shd get this dlci from bri port of router 2. Can any one help me what config does one needs to do on the bri part of router 1 & router 2.

RE: OSPF Link State [7:15008]
Slight correction, if I may: it's not that OSPF will declare a link dead after it fails to receive four packets. It will declare the link dead after it has not received any hello packets for the duration of the configured dead timer. By default the dead timer on a broadcast medium is equal to four times the hello interval, so this would indeed work out to four packets. But you could set the dead timer to 11 seconds if you really wanted to, and OSPF would declare the link dead after 11 seconds had passed without hearing a hello packet. BJ ss wrote: Hi!! OSPF uses hello packets as keepalive message.This is exchanged periodically at regular intervals between the neighbors to check if the link is alive.Suppose if the link goes down then the neighbor will not receive hello packets which means there is some problem in the link.If the neighbor does not receive 4 consecutive hello packets at the intervals defined ,then the neighbor is considere dead. After sometime if the neighbor again comes up,the router has to again establish the neighbor relationship. Hope this helps you Cheers ss Bradley J.

ATM encapsulation with 3600 interface [7:15003]
has anyone ever used ATM encapsulation with a WIC-1T serial interface in a 3600 router? i know that atm over "a" serial interface is very common, but i'm not 100% sure if its possible with the WIC-1T, and i can't seem to find documentation that specifically says so. We're setting up a PVC from a POP to our Center and the phone company has already set up the POP for 2 Mb ATM (i'm in a country in which the monopoly/government Phone Company doesn't have high speed ATM available at this location:( ) and we can't get our hands on a module that will support an E1 interface for 3 weeks. sorry for the rambling, but if anyone has ever successfully set this up, please let me know asap. thanks in advance, jason Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=15003&t=15003 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
