H-VPLS UPE dual homing configuration example
Network requirements
To improve reliability of the H-VPLS network, UPE establishes a U-PW with NPE 1 and NPE 2, respectively. The U-PW between UPE and NPE 1 is the primary PW and that between UPE and NPE 2 is the backup PW. The backup PW works only when the primary PW fails.
The H-VPLS uses LDP as the PW signaling protocol.

Configuration procedure
Configure an IGP and public tunnels on each PE. (Details not shown.)
Configure UPE:
# Configure basic MPLS.
