Big B,
While you may have already tried this, I thought I
would make the suggestion. It is possible that you
have broadcasts triggering the link, so you might be
able to use the following to stop your problem:
access-list 101 deny ip any host 255.255.255.255
This, of course, will deny all broadcasts from
triggering the link (IP). You could use the following
command with great caution to find out what is
'interesting' to your DDR connection:
debug dialer events
debug dialer packets
Also, what routing protocol are you using? EIGRP?
The multicasts it sends off will trigger a link,
unless explicitly prohibited. Simply use something
like the following:
access-list 101 deny eigrp any any
While you might have already tried this, just
thought I might be of some help as DDR can be a pain
to silence sometimes.
