David,
The unicast (s=172.168.100.5, d=172.168.100.6) indicates addresses
other than what's on the ISDN ints. Where do these addresses exist? They
would appear to be on the same subnet.

Subject: help w/demand circuit for x^99999 time
Guys,
For some reason I am unable to prevent the link from being brought up by
ospf unicast. It have set it up with both ospf non broadcast and
point-to-point, with neighbor statements. I have included the ip ospf
demand circuit, disabled cdp, and used the no peer-neighbor route. There is
no redistribution as I have turned it off to try and isolate the variable.
One of the routers is R5 and the other is Rx. Here are the configs....It
seems to be working fine except for the fact that it keeps flapping. What
gives? Any ideas? No hellos are bringing it up...seems to be unicast....
Thanks...Dave
