The ISDN section in Scenario 5 has me pretty confused because the debriefing has no backup strategy at all or I must be missing something. If we make the ISDN a backup interface for the fastethernet, then we would not be able to ping across the link, hence this is not useable.
I solved this by putting a secondary address on the fastethernet interface, and using dialer watch to watch this from R3. Granted, R3 will learn this route from both OSPF and ISIS, but this does not seem to make a difference as far as dialer watch is concerned. This seems to work whether the interface on R5 is shutdown, or the switchport on SW1 is shutdown.
Anyone else have any ideas?
Just for the record, this book does have quite a few errors. Once again I am disappointed with the quality of a Cisco Press book. I continue to hope for more out of Cisco Press, but time and time again I am disappointed.
Regards to all,
Joe
