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.
