Troubleshooting VPLS

Symptom:
The VPLS PW is not up.
Analysis:

The public network LSP tunnel is not established.

The extended session is not working normally.

A private network interface is not bound with the corresponding VPLS instance or the private
network interface is not up.

Solution:

Check the routing tables of the PEs to see whether a route is available between the two PEs. Check

whether each device can ping the loopback interface of the peer and whether the LDP session is
normal.

Check whether any extended session configuration command is missing at either side.

View the private interface status by using the display interface command. Make sure the private

interface is up.

View the current configuration by using the display current-configuration command. Make sure that

the two peers have the same PW ID and transport mode.
