IP ADDRESSING AND PROTOCOL COMMANDS
IP
PROXY-ARP
ip proxy-arp
Overview This command enables Proxy ARP responses to ARP requests on an interface.
When enabled, your device intercepts ARP broadcast packets and substitutes its
own physical address for that of the remote host. By responding to the ARP
request, your device ensures that subsequent packets from the local host are
directed to its physical address, and it can then forward these to the remote host.
Your device responds only when it has a specific route to the address being
requested, excluding the interface route that the ARP request arrived from. It
ignores all other ARP requests. See the ip local-proxy-arp command about
enabling your device to respond to other ARP messages.
The no variant of this command disables Proxy ARP responses on an interface.
Proxy ARP is disabled by default.
Syntax
