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.
