You mentioned:

"When I try to watch any /32 route, or even the /25 routes (describing
the
correct network and mask in the dialer watch-list command), dialer watch

sees that the network has disappeared from the route table, but the ISDN

doesn't dial. I'm assuming that this might have something to do with
the
dialer map command."

Did you also remember to update your dialer map statements to include
the route you are watching?

Also, when you say:

"...dialer watch
sees that the network has disappeared from the route table, but the ISDN

doesn't dial."

Are you verifying this through a debug command? Can you "debug ppp
negotiation" at the same time?

classful watched nets

Here is a route table from my lab topology

       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS

       * - candidate default, U - per-user static route, o - ODR

R2#

I configured Dialer Watch as follows:

dialer watch-list 3 ip 151.30.10.0 255.255.255.0
int bri0
dialer watch-group 3
dialer map ip 151.30.10.0 name R1 broad 5552008
dialer map ip 151.30.10.0 name R1 broad 5552009

plus the usual dialer maps and ISDN config commands on this interface.

This works fine.

When I try to watch any /32 route, or even the /25 routes (describing
the
correct network and mask in the dialer watch-list command), dialer watch

sees that the network has disappeared from the route table, but the ISDN

doesn't dial. I'm assuming that this might have something to do with
the
dialer map command.

Does this mean that you can only watch a route that meets classful
definitions? Why won't dialer watch work with these routes? I don't
remember reading any such prohibition (athough I remember reading
something
about problems with watching /32 routes).

Thanks
