unknown-destination

Description: 

Modifies the subscriber policy for packets with unknown unicast destination addresses (DAs) to define whether the subscriber (client) interfaces that belong to a bridge group or to a VPLS instance forward (permit) or filter (deny) packets with unknown unicast DAs. The no version restores the default value, deny packets with unknown unicast DAs.

You cannot change the default subscriber policy values for trunk (server) interfaces that belong to a bridge group or to a VPLS instance. You also cannot change the default subscriber policy values for a VPLS virtual core interface, which acts as a trunk interface. The VPLS virtual core interface represents all of the MPLS tunnels from the router to the remote VPLS edge (VE) devices.

Syntax:
