Proxy Address Resolution Protocol (ARP)

This section describes the Proxy Address Resolution Protocol (ARP) feature.

Overview

• Proxy ARP allows a router to answer ARP requests where the target IP address is not the
router itself but a destination that the router can reach
• If a host does not know the default gateway, proxy ARP can learn the first hop
• Machines in one physical network appear to be part of another logical network
• Without proxy ARP, a router will only respond to an ARP request if the target IP address is an
address configured on the interface where the ARP request arrived
