Configuring Static ARP Table Entries

To configure static ARP table entries, include the arp statement:

You can include this statement at the following hierarchy levels:

• [edit interfaces interface-name unit logical-unit-number family inet address address ]
• [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number family inet address address]

The IP address that you specify must be part of the subnet defined in the enclosing address statement.

To associate a multicast MAC address with a unicast IP address, include the multicast-mac statement.

Specify the MAC address as six hexadecimal bytes in one of the following formats: nnnn.nnnn.nnnn or nn:nn:nn:nn:nn:nn. For example, 0011.2233.4455 or 00:11:22:33:44:55.

For unicast MAC addresses only, if you include the publish option, the routing platform replies to proxy ARP requests.

Note: By default, an ARP policer is installed that is shared among all the Ethernet interfaces on which you have configured the family inet statement. By including the arp statement at the [edit interfaces interface-name unit logical-unit-number family inet policer] hierarchy level, you can apply a specific ARP-packet policer to an interface. For more information, see Applying Policers. When you need to conserve IP addresses, you can configure an Ethernet interface to be unnumbered by including the unnumbered-address statement at the [edit interfaces interface-name unit logical-unit-number family inet] hierarchy level. For more information, see Configuring an Unnumbered Interface.

Example: Configuring Static ARP Table Entries

Configure two static ARP table entries on the routing platform’s management interface:
