Isn't the solution to use snapshot routing?

Subject: Old wound revisited- lab 8 ISDN keeps flapping
I am yet to manage to keep this line quiet.
I would like to hear from the people who are currently working on lab 8 and
have managed to control this link.
I know that igrp redistribution could be the culprit. As a last resort, I
have removed igrp from r5 totally and shut down int s0.2.
I know BGP connection from r1-r6 could be the culprit. There was a
recommendation in the archives to lengthen the keepalive and hold periods
using BGP neighbor timers command. Although I do not see this as
ccbootcamp's solution, I lengthened this timer to 300 and 600. The chat
keeps on going & going.
Thanks,
Bernard
