Step 2 Check whether the remote label has been received.
Use the display vsi remote bgp command on PE1 and on PE2. No information appears, which
indicates that the remote label is not received.
It can be judged that BGP configuration has an error.

Troubleshooting procedure
Step 1 Check the status of the AC. Find that the AC is Up at both ends.
Step 2 Run the display vsi remote bgp command. No output appears, which indicates that the label is
not received.
Step 3 Check whether the VPN target matches.
Step 4 If the VPN target matches, ensure that the tunnel exists.
Step 5 If the tunnel exists, use the display bgp peer all command to check the setup of BGP
adjacency.
Step 6 If the BGP adjacency is set up, use the display bgp vpls all command to check whether the
remote label block is received.
Step 7 If the remote label block is not received, check BGP configuration. Find that the VPLS address
family is not configured. Configure the VPLS address family to solve the problem.
