arp

To add a permanent ARP cache entry in Global Configuration mode:
Syntax
[ no ] arp [ vrf vrfName ] ipAddress interfaceType interfaceSpecifier
[ macAddress [ validate ] ]
To modify the subscriber policy for ARP packets in Subscriber Policy Configuration
mode:
arp { permit | deny }
no arp
Command introduced before JUNOSe Release 7.1.0.
Release Information
In Global Configuration mode, adds a permanent entry in the ARP cache. This
Description
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.
