LDP PW configuration example
Network requirements
Configure VPLS on each PE, and establish LDP PWs between the PEs to interconnect the CEs.

Configuration procedure
Configure an IGP and public tunnels on each PE. (Details not shown.)
Configure PE 1:
# Configure basic MPLS.
<PE1> system-view [PE1] interface loopback 0 [PE1-LoopBack0] ip address 1.1.1.9 32 [PE1-LoopBack0] quit [PE1] mpls lsr-id 1.1.1.9 [PE1] mpls ldp [PE1-ldp] quit
# Enable L2VPN.
[PE1] l2vpn enable
# Configure VSI aaa that uses LDP as the PW signaling protocol, and establish a PW to PE 2 and PE 3, respectively.

Configure PE 2:
# Configure basic MPLS.

Configure PE 3:
# Configure basic MPLS.
<PE3> system-view [PE3] interface loopback 0 [PE3-LoopBack0] ip address 3.3.3.9 32 [PE3-LoopBack0] quit [PE3] mpls lsr-id 3.3.3.9 [PE3] mpls ldp [PE3-ldp] quit
# Enable L2VPN.

Verifying the configuration
# Execute the display l2vpn pw verbose command on PE 1. The output shows that two LDP PWs in up state have been established.
