Ade,
Thanks for the reply, I don't think you need a dialer group/list to make
dialer watch work. I changed my lab slightly and did my dialer watch configs
on another router (r6) and have it watching the loopback interface of r5.
See diagram below. The only two interfaces that are in area 1 are the serial
interfaces that connect r5 to r6 through the frame cloud. All other
interfaces are in area 1. I also included r5's loopback interface
(5.5.5.5/32) in area 1. This loopback interface is summarized into area 0 to
5.0.0.0/8 with an "area 1 range" command". R6 is watching this summary route
and is configured to bring up the ISDN link if it disappears. The relevant
portions of the configs for r1, r5, and r6 are below. This time everything
worked fine but I'm still at a loss why my previous dialer-watch setup
failed to bring up the link. I didn't use dialer lists/groups below. My
config below works without them........ For kicks I added a dialer
list/group command before I tore down my old setup, to denied all ip
traffic, but still no luck. I'm not sure why this setup works but my
configuration in my original post failed. They are very similar.

think you need to put a dialer-group statement under the BRI interface. You
can deny all traffic in the dialer-list if you need to but I feel this
command is needed for the interface to behave as desired.
