MPLS Fundamentals

Verifying the VPLS Operation

The output of Example 11-2 is taken on the router VPLS-PE-1 depicted in Figure 11-6. You use the show vfi command to verify the existence and state of the VFI cust-one.

Example 11-2. show vfi

VPLS-PE-1#show vfi cust-one VFI name: cust-one, state: up Local attachment circuits: Vlan111 Neighbors connected via pseudowires: 10.100.100.2 10.100.100.3

The show mpls ldp neighbor command verifies the existence of the targeted LDP sessions between all PE routers for the VFI cust-one. In Example 11-3, VPLS-PE-1 has two targeted LDP sessions for the two remote PEs and one direct LDP neighbor: a P router.

Example 11-3. show mpls ldp neighbor

VPLS-PE-1#show mpls ldp neighbor Peer LDP Ident: 10.100.100.4:0; Local LDP Ident ...
