H-VPLS using MPLS access configuration example
Network requirements
Configure an H-VPLS using MPLS access to avoid full-mesh PW configuration. 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.
<UPE> system-view [UPE] interface loopback 0 [UPE-LoopBack0] ip address 1.1.1.9 32 [UPE-LoopBack0] quit [UPE] mpls lsr-id 1.1.1.9 [UPE] mpls ldp [UPE-ldp] quit
# Enable L2VPN.
[UPE] l2vpn enable
# Configure VSI aaa to use LDP to establish a U-PW to NPE 1.

Configure NPE 3:

Verifying the configuration
# Execute the display l2vpn pw verbose command on each PE. The output shows that PWs in up state have been established.
