The whole key to dialer-watch is to get an exact match within the
routing table. Check how the route shows up in your routing table on the
watching router when the route is still up. Then define your dialer
watch list accordingly.
Kind regards
James

Subject: Dialer Watch Puzzle
Hello,
I am working on a lab, which has R5 and R6 connected via a frame-relay
link and isdn as backup. I have configured dialer-watch on R5 to watch
the loopback on R6 (129.6.6.6/32). When I shut down the serial interface
on R6, R5 DOES NOT trigger the call. I know my ISDN is working as I can
ping the remote interface and bring the link up. Also, ran a debug
dialer on R5 and it sees that the watched network is down but does not
place the call. I think I have all the required config for dialer watch
on R5 (dialer watch-group, dialer watch-list and the dialer map for the
watched network). I also checked the network that I am watching via show
ip route (see below)
Any advice?
Here is my config for R5 and R6 and output from debug dialer
