LDP PW configuration example

CEs are connected to the PEs through Layer 3 Ethernet interfaces (GigabitEthernet 2/1/1).

Configure a VSI on each PE, and establish LDP PWs between the PEs to interconnect the CEs.

1. Configure an IGP and public tunnels on each PE. (Details not shown.)

2. 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 PWs to PE 2 and PE 3.

   [PE1] vsi aaa
   [PE1-vsi-aaa] pwsignaling ldp
   [PE1-vsi-aaa-ldp] peer 2.2.2.9 pw-id 500
   [PE1-vsi-aaa-ldp-2.2.2.9-500] quit
   [PE1-vsi-aaa-ldp] peer 3.3.3.9 pw-id 500
   [PE1-vsi-aaa-ldp-3.3.3.9-500] quit
   [PE1-vsi-aaa-ldp] quit
   [PE1-vsi-aaa] quit
   

   # Bind Layer 3 Ethernet interface GigabitEthernet 2/1/1 to VSI aaa.

   [PE1] interface gigabitethernet 2/1/1
   [PE1-GigabitEthernet2/1/1] xconnect vsi aaa
   [PE1-GigabitEthernet2/1/1] quit
   

3. Configure PE 2:

   # Configure basic MPLS.

   <PE2> system-view
   [PE2] interface loopback 0
   [PE2-LoopBack0] ip address 2.2.2.9 32
   [PE2-LoopBack0] quit
   [PE2] mpls lsr-id 2.2.2.9
   [PE2] mpls ldp
   [PE2-ldp] quit
   

   # Enable L2VPN.

   [PE2] l2vpn enable
   

   # Configure VSI aaa that uses LDP as the PW signaling protocol, and establish PWs to PE 1 and PE 3.

   [PE2] vsi aaa
   [PE2-vsi-aaa] pwsignaling ldp
   [PE2-vsi-aaa-ldp] peer 1.1.1.9 pw-id 500
   [PE2-vsi-aaa-ldp-1.1.1.9-500] quit
   [PE2-vsi-aaa-ldp] peer 3.3.3.9 pw-id 500
   [PE2-vsi-aaa-ldp-3.3.3.9-500] quit
   [PE2-vsi-aaa-ldp] quit
   [PE2-vsi-aaa] quit
   

   # Bind Layer 3 Ethernet interface GigabitEthernet 2/1/1 to VSI aaa.

   [PE2] interface gigabitethernet 2/1/1
   [PE2-GigabitEthernet2/1/1] xconnect vsi aaa
   [PE2-GigabitEthernet2/1/1] quit
   

4. 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.

   [PE3] l2vpn enable
   

   # Configure VSI aaa that uses LDP as the PW signaling protocol, and establish PWs to PE 1 and PE 2.

   [PE3] vsi aaa
   [PE3-vsi-aaa] pwsignaling ldp
   [PE3-vsi-aaa-ldp] peer 1.1.1.9 pw-id 500
   [PE3-vsi-aaa-ldp-1.1.1.9-500] quit
   [PE3-vsi-aaa-ldp] peer 2.2.2.9 pw-id 500
   [PE3-vsi-aaa-ldp-2.2.2.9-500] quit
   [PE3-vsi-aaa-ldp] quit
   [PE3-vsi-aaa] quit
   

   # Bind Layer 3 Ethernet interface GigabitEthernet 2/1/1 to VSI aaa.

   [PE3] interface gigabitethernet 2/1/1
   [PE3-GigabitEthernet2/1/1] xconnect vsi aaa
   [PE2-GigabitEthernet2/1/1] quit
   

# Verify that two LDP PWs in up state have been established on PE 1.
