Configuring the Protect Interface
You can configure a protect interface for the logical interface linking a virtual circuit to its destination, whether the destination is remote or local. A protect interface provides a backup for the protected interface in case of failure. Network traffic uses the primary interface only so long as the primary interface functions. If the primary interface fails, traffic is switched to the protect interface. The protect interface is optional.
To configure the protect interface, include the protect-interface statement:
protect-interface interface-name;
For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.
