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
—One configured interface is randomly designated as the active interface for the
any
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
statement:
active-interface
active-interface {
any;
primary interface-name;
}
You can include this statement at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls site site-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls site site-name]

Configuring Multihoming on the PE Router

When a CE device is connected to the same VPLS site on more than one PE router, include
the multi-homing statement on all associated PE routers. Configuration of this statement
tracks BGP peers. If no BGP peer is available, VPLS deactivates all active interfaces for
a site. To specify that the PE router is part of a multihomed VPLS site, include the
statement:
multi-homing
multi-homing;
You can include this statement at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls site site-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls site site-name]
Include the multi-homing statement on all PE routers associated with a particular VPLS
site.
All VPLS single-homed sites are connected to the same default VE device. All interfaces
in a VPLS routing instance that are not configured as part of a multihomed site are
assumed to be single-homed to the default VE device.
