Filtering BGP from the dialer list should only keep BGP from bring up dial
as interesting traffic. Once the dial circuit is up and the primary has gone
away, given Loopback peers, I don't see why the BGP routes/keeps should not
flow freely. Do I understand the topology correctly? Router --- Primary Link
with BGP peer hooked to a loopback and backup link via ISDN to another site.
The site you dial into must also have the peer statement to your loopback.
During normal ops, that site should be able to reach you via serial link and
during disaster recovery, when OSPF routes have converged and the loopback
is again reachable, the BGP peer should come up.
