Release Information

Command introduced before JunosE Release 7.1.0.

Description

In Global Configuration mode, adds a permanent entry in the ARP cache. This command applies only to Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet interfaces, and bridged Ethernet interfaces configured over ATM 1483. The no version removes an entry from the ARP cache.

In Subscriber Policy Configuration mode, modifies the subscriber policy for ARP to define whether the subscriber (client) interfaces belonging to a bridge group or VPLS instance forward (permit) or filter (deny) ARP packets. The no version restores the default value, permit ARP packets.

In Subscriber Policy Configuration mode, you cannot change the default subscriber policy values for trunk (server) interfaces belonging to a bridge group or VPLS interface. 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) device.
