H-VPLS using MPLS access configuration example
Network requirements
Configure an H-VPLS network 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.

# Bind Layer 3 Ethernet interface GigabitEthernet 2/1/1 to VSI aaa.
[UPE] interface gigabitethernet 2/1/1 [UPE-GigabitEthernet2/1/1] xconnect vsi aaa [UPE-GigabitEthernet2/1/1] quit
Configure NPE 1:
# Configure basic MPLS.
<NPE1> system-view [NPE1] interface loopback 0 [NPE1-LoopBack0] ip address 2.2.2.9 32 [NPE1-LoopBack0] quit [NPE1] mpls lsr-id 2.2.2.9 [NPE1] mpls ldp [NPE1–ldp] quit
# Enable L2VPN.
[NPE1] l2vpn enable
# Configure VSI aaa that uses LDP as the PW signaling protocol, establish a U-PW to the UPE, and establish N-PWs to NPE 2 and NPE 3.

Configure NPE 2:
# Configure basic MPLS.

[NPE2] interface gigabitethernet 2/1/1 [NPE2-GigabitEthernet2/1/1] xconnect vsi aaa [NPE2-GigabitEthernet2/1/1] quit
Configure NPE 3:
# Configure basic MPLS.

Verifying the configuration
# Verify that PWs in up state have been established on each PE.
