3.4.3 Example for Associating PW Redundancy with E-APS
Working in 1:1 Mode
This section provides a configuration example for associating PW redundancy with E-APS
working in 1:1 mode. A networking diagram is provided to demonstrate the configuration
procedure. The configuration example includes networking requirements, configuration
roadmap, configuration procedure, and configuration files.

As shown in
occurs on the network side, the switchover of TE groups rather than PWs is performed. When
a fault occurs on the AC side, the switchover between the working interface and the protection
interface is performed on the AC side according to APS. This leads to the switchover of PWs
and thus avoids the loss of the network data.
