Configure Inverse ATM 1 or ATM 2 ARP

For ATM 1 and ATM 2 interfaces, you can configure inverse ATM ARP, as described in RFC 2225. When inverse ATM ARP is enabled, the router responds to received Inverse ATM ARP requests by providing IP address information to the requesting ATM device.

The router does not initiate inverse ATM ARP requests.

By default, inverse ATM ARP is disabled. To configure a VC to respond to inverse ATM ARP requests, include the inverse-arp statement at the [edit interfaces interface-name unit logical-unit-number] or [edit interfaces interface-name unit logical-unit-number family inet address address multipoint-destination destination] hierarchy level:

inverse-arp; 

You must configure ATM LLC-SNAP encapsulation on the logical interface to support inverse ARP. No other ATM encapsulation types are allowed. For more information, see Configure ATM 1 and ATM 2 Interface Encapsulation.
