Specifying an Interface as the Active Interface

You need to specify one of the interfaces for the multihomed site as the primary interface. If there are multiple interfaces, the remaining interfaces are activated only when the primary interface goes down. If no active interfaces are configured at the site level, all traffic for a VPLS site travels through a single, non-multihomed PE router.

You must configure one of the following options for the active-interface statement:

• any—One configured interface is randomly designated as the active interface for the VPLS site.
• primary—Specify the name of the multihomed interface to be used as the primary interface by the VPLS site.

To specify a multihomed interface as the primary interface for the VPLS site, include the active-interface statement:

active-interface {

    any;

    primary interface-name;

}

You can configure this statement at the following hierarchy levels:

• [edit routing-instances routing-instance-name protocols vpls site site-name]
• [edit logical-routers logical-router-name routing-instances routing-instance-name protocols vpls site site-name]
