I see this same problem from a different perspective: In a PM-3/PM-2
environment (both running OSPF) where the PM-3 is (PRI) inbound only and
the PM-2 has ISDN lines. When you ask the PM-2 to make an outbound
connection there is no way to prioritize which link the traffic flows on.
In this case the outbound traffic goes via the PM-2 and the inbound traffic
via the PM-3. Not very helpful when you've dialing a client router
probably to troubleshoot a problem!
