Dave,
You need to filter whatever route for the network that the bri interface is
on. You do not need to block all redistributed routes; just prevent the
route that points to the isdn network from being advertised back into the
ospf domain.
I learned my lessons from bootcamp lab8. Boy, was that one a killer!

Subject: ISDN flapping
Hi,
I am having an issue with my ISDN line flapping. I have ip ospf demand
circuit and I am blocking any redistributed routes but the line is still
going up and down. When I use the show dialer command to see the cause of
the line going up it has the source as the ip address of the BRI interface
and the destination to the other ends ip address of the BRI interface.
EX.
R1(BRI0)---------------------------(BRI1/0)R2
133.1.100.5/30 133.1.100.6/30
sh dialer map
dialing cause
133.1.100.5---133.1.100.6 ??????
Any thoughts as to what this is?
Thanks,
David
