RE: eigrp and isdn routing question? [7:28219]
If you deny EIGRP multicasts in the dialer-list it will prevent them from initiating a call or keeping the line up. They will be uninteresting. and will not cause the line to dial. Once the line is up, all packets are fair game regardless of whether or not they match the dialer-list. Any packet is passed over the ISDN circuit. The dialer-list only signifies what traffic is interesting and will force a call. I'm not sure if this is what you are looking for. In other words, neighbors would only be formed when the link was up due to some other traffic defined interesting by the dialer-list. No more interesting traffic and the link comes down, but EIGRP will not keep the circuit up or cause a call to be initiated.. You should probably look at the dialer-watch command for dial backup over EIGRP. I think dialer-watch might be just what the doctor ordered. -Original Message- From: Bob Perez [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 05, 2001 1:09 PM To: [EMAIL PROTECTED] Subject: eigrp and isdn routing question? [7:28219] Is ther a way that I can stop all eigrp traffic from passing on the ISDN when it is down and then to pass when the ISDN comes up? I have an access list that denies eigrp on the BRI and the interface is set as passive in the eigrp config. But I am having routing problems when I lose my serial line and the ISDN comes up. Nothing will route unless there is a hardcoded next hop for an address "ip route ** ** *" I would like to somehow pass eigrp info over the isdn when it comes up but not when it is down? Can this be done. I also do not want to do redistribute static because of default gateway issues. Thanks.

Re: eigrp and isdn routing question? [7:28219]
I'm guessing you want EIGRP routing to occur over this link when it is up but you do not want to define EIGRP as interesting. Get rid of the passive and add something like: interface BRI0/0 dialer-group 1 ! access-list 101 deny eigrp any any access-list 101 permit ip any any ! dialer-list 1 protocol ip list 101 Dave Bob Perez wrote: > > Is ther a way that I can stop all eigrp traffic from passing on the ISDN > when it is down and then to pass when the ISDN comes up?

Re: eigrp and isdn routing question? [7:28219]
Dave, I see how you setup your ACL to make EIGRP traffic "uninteresting" which will keep the ISDN from dialing. I understand that, but what would keep the interesting traffic (which is everything besides EIGRP) from dialing and keeping the ISDN dialed all the time? i.e. if this ISDN was only to be used in the case of dial-backup, what keeps it from being up when a "primary" (let's say serial) link is up? Just curious. I'm trying to think about a situation where a remote site would have, say, a 2500 series router with a serial and BRI interface. Let's also say you wanted the BRI only to dial when the serial link was down. Can you accomplish this while at the same time using the ACL you suggested to keep EIGRP traffic from going across the link? Thanks! Mike W.
