no-revert (Local Switching)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 11.4.

Description

(Optional) Prevent the local switching interface from reverting to the primary interface.

Note

The protect interface must be configured prior to configuring the no-revert statement.

Typically, when the primary interface goes down, the pseudowire starts using the protect interface. By default, when the primary interface comes back online, the interface is switched-over back from the protect interface to the primary interface. To prevent the switchover back to the primary interface, unless the primary interface goes down, include the no-revert statement. This prevents loss of traffic during the switchover.

Note

If the protect interface fails, the interface is switched-over back to the primary interface, irrespective of whether or not the no-revert statement is included in the configuration.

This statement can be configured both for the starting interface and the ending interface.
