ip proxy-arp
Use the ip proxy-arp command in Interface Configuration mode to enable proxy ARP on a
router interface. Without proxy ARP, a device only responds to an ARP request if the target IP
address is an address configured on the interface where the ARP request arrived. With proxy
ARP, the device may also respond if the target IP address is reachable. The device only responds
if all next hops in its route to the destination are through interfaces other than the interface that
received the ARP request. Use the no form of the command to disable proxy ARP on a router
interface.
