Thanks Pearson.
Some reason its not working that way.
Once BRI comes up...there is a new /32 route introduced for the
watched network 150.1.5.0/32 network. ((is this a problem ??))
There are two networks seen once BRI is up. sh ip route =>
150.1.5.0/24 through serial & 150.1.5.5/32 via BRI.
Tried with "no peer neighbor-route" did not help either.
