Hi Zape,
Couple of things -
1 - only apply 'ospf demand-circuit' on one side of the connection. If one
side of the connection is the hub-side of a hub-and-spoke relationship then
apply the demand-circuit to the hub's bri only.
2 - sometimes, I have to let isdn bring up the call one time normally, and
after the call is up and the networks are converged, then I apply the
demand-circuit on the hub side.
3 - I don't see the username/password combo on r2 for r1.
4 - which side is dialing out? I see the dial#s on both sides. Are they
both placing a call at the same time? Try letting just the demand-circuit
side place the call.
5 - This link may help
http://www.cisco.com/warp/public/104/dcprob.html
6 - you mention that "no peer neighbor" is applied but I don't see it in the
configs - I always keep that command applied (even when troubleshooting)
7 - try taking off the priority 0 off of r1. I think ISDN is considered a
point-to-point (but I could be totally wrong on this one - I spend 20 mins
trying to find this answer on CCO, Doyle and Solie and did not find a
definitive answer).
HTH,
Sean
Demand-circuit has a life of its own. Most of my suggestions are probably
useless.

Subject: ISDN 224.0.0.5 problem
Hello,
I am having a problem with my isdn.For one the multicast address 224.0.0.5
is bringing the link up. By the way I am not doing any redistribution.
When I do sh ip osp neigh on R1, I don't see no neighbor id toward R2.
When I apply the same command on R2, I see that R2 is try to establish a
neighbor with R1. I already tried the no peer neighbor-route on both
command. I tried to command deb ip ospf monitor I can't apply on my routers
even I am running the 12.2 code.
Any help will be appreciated.
Thanks
Zape
