Troubleshooting MPLS L2VPN
This section describes troubleshooting techniques for MPLS L2VPN.
Symptom
After the L2VPN configuration, the peer PEs cannot ping each other. The display mpls l2vc command output shows that the VC is down and the remote VC label is invalid (displayed as --).
Analysis
The reason the VC is down might be that the PEs are configured with different encapsulation types.
Solution
Verify that the local PE and the peer PE are configured with the same encapsulation type.
Verify that the PEs are correctly configured with the remote peers.
