Verifying the configuration
# Execute the display vpls connection command on each device. The output shows that a PW in
up state has been established between the devices.

Troubleshooting VPLS

Symptom
The VPLS PW is not up.
Analysis
•
The public network LSP tunnel is not established.
•
The extended session is not working correctly.
•
A private network interface is not bound to the corresponding VPLS instance or the private
network interface is not up.
Solution
1. Check the routing tables of the PEs to verify that a route is available between the two PEs.
Verify that each device can ping the loopback interface of the peer and whether the LDP
session is normal.
2. Verify that any extended session configuration command is not missing at either side.
3. Display the private interface status by using the display interface command. Make sure the
private interface is up.
4. Display the current configuration by using the display current-configuration command. Make
sure the two peers have the same PW ID and transport mode.
