Configure Inverse Frame Relay ARP

Frame Relay interfaces support inverse Frame Relay ARP, as described in RFC 2390. When inverse Frame Relay ARP is enabled, the router responds to received inverse Frame Relay ARP requests by providing IP address information to the requesting router on the other end of the Frame PVC (permanent virtual circuit).

The router does not initiate inverse Frame Relay ARP requests.

By default, inverse Frame Relay ARP is disabled. To configure a router to respond to inverse Frame Relay 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:

[edit interfaces interface-name unit logical-unit-number] 

inverse-arp; 

You must configure Frame Relay encapsulation on the logical interface to support inverse ARP. For more information, see Configure Interface Encapsulation.
