Use this command to enable proxy ARP on an interface.
| default-route | (Optional) Sets the router to respond to ARP requests for hosts that are only reachable using the default route. Typically, proxy arp is only used to reply to requests for hosts that are reachable via a non-default route. |
| local | (Optional) Allows the router to respond to ARP requests that are received on the interface to which this command is applied if the target IP address of the request is reachable on the interface that received the request. |
Configuration command, Interface configuration command mode.
This variation of the ARP protocol allows the routing module to send an ARP response on behalf of an end node to the requesting host. Proxy ARP can lessen bandwidth use on slow-speed WAN links. It is enabled by default without the default route or local options set.
The “no” form of this command disables proxy ARP
This example shows how to enable proxy ARP:
System(rw-config)->interface vlan 1 on VLAN 1: System(rw-config-intf-vlan.0.1)->ip proxy-arp
