ARP Table

To maintain the Address Resolution Protocol (ARP) table, you can use either static mapping via the CLI or Inverse ARP (InARP). InARP provides a way of determining the IP address of the device at the far end of a circuit. For NBMA interfaces, InARP enables automatic creation of ARP table entries for each circuit on the interface.

You must enable InARP when you create a PVC by using the atm pvc command. After you configure InARP, a protocol mapping between an ATM PVC and a network address is learned dynamically as a result of the exchange of InARP packets.
