no-revert (Neighbor Interface)


Hierarchy Level


(Optional) Prevent the protect interface from reverting to the primary interface.


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 protect interface goes down, include the no-revert statement. This prevents loss of traffic during the switchover.


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.
