We added a 2nd point-to-point T1 connection to our 2650XM router that goes to a Nortel BLN (Backbone Link Node) Router. The problem we have is that once we add the second T1 to the multi-link PPP group, all traffic stops routing.
Has anyone seen anything like this before? What about some good debugs to troubleshoot this? I'm thinking multi-link ppp incompatibilities/configuration options between the Cisco and the Nortel MLPPP implementation, but need some ideas on how I can prove it is one side or the other.
Any thoughts would be appreciated-
Ryan
