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.
