If you do not have any other routing protocol there, the BGP session
should be broken because when you use loopback as the neighbor you need
a static route to route the loopback to the right interface or the next
hop IP address. In either case if the PVC goes down, neither interface
no the next hop IP address is available, therefore it will cause the
BGP session down. As long as you do not route the loopback IP via your
ISDN circuit, the BGP can not run through the ISDN line since it do not
know how to get to the neighbor IP address which is the loopback IP
address.
Hope this would help.
Thanks,
Song
