Chapter 9 Proxy Address Resolution Protocol (ARP) This chapter describes the Proxy Address Resolution Protocol (ARP) feature. • 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 Proxy ARP Examples The following are examples of the commands used in the proxy ARP feature. CLI: show ip interface (Netgear Switch) #show ip interface ? brief Enter an interface in slot/port format. Display summary information about IP configuration settings for all ports.
