Example: Configuring H-VPLS UPE dual homing
Network configuration
To improve reliability of the H-VPLS network, the UPE establishes a U-PW with NPE 1 and NPE 2. 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.
