6.10 Configuring PWE3 FRR
This section describes how to configure PW FRR. After PW FRR is configured, the L2VPN
traffic can be timely switched to backup path as soon as the master path fails. After the master
path recovers, the L2VPN traffic can be switched back to it according to the revertive switching
policy.
6.10.1 Establishing the Configuration Task
Applicable Environment
The PW FRR supported by the S7700 is mainly used on the network where the CEs are
asymmetrically connected to PEs.
In such networking, one CE of the VC is connected to a more reliable PE through a single link
of higher reliability. The other CE is dual-homed to the PEs of lower reliability. Two paths thus
exist between the CEs. The path with higher reliability is the master path, and the path with
lower reliability is the backup path.
The revertive switchover policy is required only in the networking where the CEs are
asymmetrically connected to PEs. By default, a delay is set for the revertive switchover.
