I would appreciate some help with this, I am not able to get the interworking L2VPN on R1 & XR2 (between R7 & R8) working. All the verificatons pass but the circuit will not pass broadcast or multicast traffic nor form the OSPF neighborship between R7 & R8 (plenty of packets back & forth but debug ip ospf adj does not show any reaching either R7 or R8).
Sorry in advance for the long post.
Thanks,
John
