Figure 73 PE dual homing
VPLS uses the backup U-PW if one of the following conditions exists:
The tunnel over which the primary PW is established is deleted, causing the primary PW to go
•
down.
BFD detects that the primary PW fails.
•
The primary PW is deleted by the control plane because the LDP session between the PEs on the
•
primary PW is down.
A primary/backup PW switchover is manually performed.

VPLS configuration task list
To configure a VPLS network, complete the following tasks:
Configure an IGP to ensure IP connectivity within the backbone network.
•
•
Configure basic MPLS or LDP to establish public tunnels on the backbone network.
Configure VPLS on PEs. For example, configure a VSI, establish a PW, and associate an AC with a
•
VSI.
This chapter describes only VPLS configurations on a PE. For more information about other configurations,
