6.7 Configuring a Backup PW
To configure PW FRR in the scenario where CEs are asymmetrically connected PEs, you need
to configure a backup PW. After the master PW fails, traffic can be switched to the backup PW.
6.7.1 Establishing the Configuration Task
Before configuring a backup PW, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task correctly and quickly.
Applicable Environment
In the PWE3 FRR network where CEs are asymmetrically connected to PEs, a backup PW needs
to be configured.

, the master PW and backup PW need to be configured on PE1. Only
one PW is required on PE2 and PE3.
On an inter-AS L2VPN and an MH PWE3, the ASBR and SPE do not distinguish the master
and backup PWs.
