To add a permanent ARP cache entry in Global Configuration mode:
[ 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.
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.

characters
ipAddress—IP address in 32-bit dotted-decimal format corresponding to the local data
link address
interfaceType—Interface type; see "Interface Types and Specifiers" on page 5
interfaceSpecifier—Particular interface; format varies according to interface type; see
Interface Types and Specifiers on page 5
macAddress—MAC address of the interface
validate—Allows the inclusion of MAC validation entries
permit—Specifies that the subscriber interface associated with the bridge group or
VPLS instance forwards ARP packets
deny—Specifies that the subscriber interface associated with the bridge group or VPLS
instance filters ARP packets
