Troubleshooting MPLS L2VPN
PEs cannot ping each other. The display mpls l2vc command output shows that the VC is down and the
remote VC label is invalid.
The reason the VC is down may be that the PEs are configured with different encapsulation types.
Verify that the local PE and the peer PE are configured with the same encapsulation type.
Verify that the remote peer is correctly configured on each PE.
