Hi All
I have an issue in backup link connectivity (ISDN).
During testing we shutdown the Primary MPLS link to switch the traffic to ISDN. ISDN is triggering but LAN(Branch) to LAN(HO) ping and traffic is not flowing.
Attached is the debug ip packet which was captured from branch during testing.
Following encapsulation failed error is also observed.
Anyone can pls help me out.
