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
1. Configure an IGP and public tunnels on each PE. (Details not shown.)
2. Configure UPE:
# Configure basic MPLS.
system-view
[UPE] interface loopback 0
[UPE-LoopBack0] ip address 1.1.1.1 32
[UPE-LoopBack0] quit
[UPE] mpls lsr-id 1.1.1.1
[UPE] mpls ldp
[UPE-ldp] quit
# Enable L2VPN.
[UPE] l2vpn enable
# Configure VSI aaa that uses LDP as the PW signaling protocol, and establish the primary PW to
NPE 1 and the backup PW to NPE 2.
[UPE] vsi aaa
[UPE-vsi-aaa] pwsignaling ldp
[UPE-vsi-aaa-ldp] peer 2.2.2.2 pw-id 500
[UPE-vsi-aaa-ldp-2.2.2.2-500] backup-peer 3.3.3.3 pw-id 500
