In response to your question: I hope I haven't violated any restriction
about size of posting but here is the configuration on each end. I thought
about editing it down, but then I thought maybe I'd delete something that
was significant that I hadn't previously noticed. This is a test bed so I
am only watching a loopback (Lo0) on the other end. I am running EIGRP, the
route shows up as connected through S1 when it is connected, and when I pull
the S1 line on the r4500b the dialer watch points out that the primary is
down but it never seems to make an effort to dial the other end. If I
attempt to ping the watch address nothing happens, but if I ping the other
end of the ISDN line, it comes up, but it doesn't seem very healthy. I
included the debug dialer output from that session at the very end of the
page.
