This sounds like our Lab 8. Are you also filtering the connected
interface on router r6?

Subject: OSPF on demand and IGRP
I know there has been a lot of discussion on this subject and rest
assured i
have been through the archives too. I have successfully tested this
feature
and it works fine but there was one problem that i could not figure out.
In
one of the practice labs i was doing a router configured for mutual
redistribution between IGRP and OSPF was also running OSPF On demand
circuit. Initially whenever the idle time out expired and the BRI came
down
it was immediately kicked back on by OSPF but then i figured out that i
needed to put in a filter at IGRP to OSPF redistribution point and that
fixed it. But then there was this requirement that the ISDN comes up
only
when the ethernet interface goes down. I should mention that there was a
serial 0 and serial 1 interface that were both running OSPF also. What i
could not figure out was how to bring up the ISDN only when the ethernet
goes down. What i think is that a topology change brings up the on
demand
circuit and there is no way to restrict this topology change .. right ?

Atif
