RE: I'm stumped! (was EIGRP over ISDN) LONG
we had a very similar issue with flapping neighbours - our problem was the NAT config we were using. Maybe you can post the configs of both routers so we can look Andrew -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: 03 January 2001 17:51 To: [EMAIL PROTECTED] Subject: I'm stumped! (was EIGRP over ISDN) LONG I'm reposting this in the hopes that someone who didn't see it before might have some ideas about this. Heck, SWAGs, educated guesstimates, or telephone psychic impressions are also welcome. We are completely stumped about how to resolve this. I've even posted this question on the CCO Q&A Forum but I don't think anyone has been answering questions on there lately. Here is the problem: we have an ISDN BRI backup link between two sites, and we want to run eigrp over the link when it's in use. The problem is that even though the line is not flapping, eigrp is behaving as if it were flapping. My side NEVER sees hellos from the other side, but it does receive updates. The other side receives my hellos, but it thinks the link is bouncing and that my router is intermittently unavailable. My side never establishes the other as a neighbor. I've used every debugging command I can find to no avail. Nothing is giving me any information that I don't already know. We have no access lists configured, except for distribute lists but that shouldn't affect neighbor relationships, should it? Here is sample debug output (debug eigrp neighbors and debug eigrp packet): 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up 3d01h: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state to up 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: EIGRP: Received UPDATE on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x1, Seq 67/0 idbQ 0/0 3d01h: EIGRP: Neighbor(10.120.226.2) not yet found 3d01h: EIGRP: Received UPDATE on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x1, Seq 67/0 idbQ 0/0 3d01h: EIGRP: Neighbor(10.120.226.2) not yet found 3d01h: %ISDN-6-CONNECT: Interface BRI0:1 is now connected to 303xx theirrouter 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: EIGRP: Received UPDATE on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x1, Seq 67/0 idbQ 0/0 3d01h: EIGRP: Neighbor(10.120.226.2) not yet found 3d01h: EIGRP: Received UPDATE on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x1, Seq 67/0 idbQ 0/0 3d01h: EIGRP: Neighbor(10.120.226.2) not yet found 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: EIGRP: Sending HELLO on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x0, Seq 0/0 idbQ 0/0 iidbQ un/rely 0/0 3d01h: EIGRP: Received UPDATE on BRI0 nbr 10.120.226.2 3d01h: AS 2, Flags 0x1, Seq 67/0 idbQ 0/0 3d01h: EIGRP: Neighbor(10.120.226.2) not yet found Here is some info from the remote side: theirrouter# 1d02h: EIGRP: Retransmission retry limit exceeded 1d02h: EIGRP: Holdtime expired 1d02h: EIGRP: Neighbor 10.120.226.1 went down on BRI0/0 1d02h: EIGRP: New peer 10.120.226.1 theirrouter#sho ip eigrp neighbors IP-EIGRP neighbors for process 2 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num 0 10.120.226.1BR0/0 12 00:00:380 5000 1 0 1d02h: EIGRP: Retransmission retry limit exceeded 1d02h: EIGRP: Holdtime expired 1d02h: EIGRP: Neighbor 10.120.226.1 went down on BRI0/0 1d02h: EIGRP: New peer 10.120.226.1 I'm not getting any errors on the line, and further debugging (isdn q921, isdn q931, ppp error, ppp auth, ppp neg, bri-interface) does not show any problems whatsoever.

Why don't you post the configs? Also send them to me @ [EMAIL PROTECTED] It sounds like a config problem. Are you using dialer-watch? What does your dialer-list look like? Do you have the "broadcast" keyword on your map statements? On both sides?

Re: I'm stumped! (was EIGRP over ISDN) LONG
Yes, we've tried 11.2(19), 12.0(14) and 12.1(5) on this end. The remote side has been on 12.0(5) the entire time and they are not able to change at this time. Since it appears to be an issue with the timers, we can set those with ios commands and hopefully alleviate the problem.

Re: I'm stumped! (was EIGRP over ISDN) LONG
Yep, the line is configured correctly and functioning end-to-end with no physical errors. We did initially have a problem with the spids and switch-type because our wonderful provider Qwest has a sucky support department that doesn't even know the difference between switch types. They kept telling us that the remote side was a dms-100 when it was actually a basic-ni1. Once we figured that out, calls began to setup correctly. > >Is the spid number's configured right? and did you check to see if Demarc > is puch down right ___ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

CDP is disabled on both ends and we are in the same 'AS'. I've thought about the timers because I was reading on CCO that the default hello timer on a slower link like a BRI is 60 seconds. However, my side is sending hellos every five seconds as I expected. I need to see if the other side has default timer settings different from mine. As I mentioned, we are running 12.1(5) and they have 12.0(5). There just might be a difference in timer settings. Thanks for the tip! > John > > Just had a bout with ISDN myself.

We are not using dialer profiles since there is only one call destination. We have CHAP configured on the physical BRI interface and I see no problems with it.
