•
The primary U-PW is deleted by the control plane. For example, the LDP session on the primary
U-PW link is down, causing the primary U-PW to be deleted.
•
BFD detects a failure of the primary U-PW.
•
A primary and backup U-PW switchover is triggered by a command.
As a best practice, execute the
port
bridge
enable
command on the NPE 1' interface connected to
NPE 4 when the following conditions are met:
•
The MPLS network (edge domain)
is configured with a fast switchover mechanism, for
example, LDP FRR or MPLS TE FRR.
•
A primary tunnel is established over the link UPE—NPE 1, and a backup tunnel is established
over the link UPE—NPE 4—NPE 1.
When the primary tunnel fails, traffic will be immediately switched to the backup tunnel. The failover
time is so short that the U-PW switchover from primary to backup might not be triggered. In this
scenario, NPE 1 needs to forward traffic received from NPE 4 to NPE 4, NPE 3, and NPE 2 in the
backbone domain. To ensure correct forwarding, execute the
port
bridge
enable
command on the
NPE 1' interface connected to NPE 4. Then, NPE 1 can send traffic received on the interface out of
the interface itself.
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, LDP, GER, or MPLS TE to establish public tunnels on the backbone
network.
•
Configure VPLS on PEs. For example, configure a VSI, establish a PW, and associate an AC
and a VSI.
This chapter describes only VPLS configurations on a PE. For more information about other
configurations, see relevant configuration guides.
To configure VPLS on a PE, perform the following tasks:
