If a serial interface, shut down the interface on the opposite side of the
link. The side where the backup interface is defined will then show "Down"
instead of "Admin down"

I don't think callback has anything affect either way. I have seen in our
production network where a shut down of the primary interface will not "wake
up" the BRI or Async. I think the IOS is smart enough to realize that it
was administratively shutdown. Try pulling the cable out of the router or
shutting down the frame switch interface that leads to this router. That
should wake up the BRI interface.

Subject: isdn backup
Hi, group
I made a isdn backup for my s0.1. The isdn is active, but
if I set the backup int b0 command, the b0 into the
standby status.And don't active forever, even I shutdown
the s0.1, maybe I couldn't use the callback in the same
time?
