8. ARP

Proxy Address Resolution Protocol

Proxy ARP allows a router to answer ARP requests when the target IP address is not that of 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 responds to an ARP request only 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 ?

<slot/port> Enter an interface in slot/port format.
