19.5.5 ip proxy-arp
Command:
ip proxy-arp
no ip proxy-arp
Function:
Enables proxy ARP for VLAN interface; the “no ip proxy-arp” command disables proxy ARP.
Default:
Proxy ARP is disabled by default.
Command mode:
VLAN Interface Mode
Usage Guide:
When an ARP request is received on the layer 3 interface, requesting an IP address in the same IP
segment of the interface but not the same physical network, and the proxy ARP interface has been
enabled, the interface will reply to the ARP with its own MAC address and forward the actual packets
received. Enabling this function allows machines to physically be separated but in the same IP
segment and communicate via the proxy ARP interface as if in the same physical network. Proxy
ARP will check the route table to determine whether the destination network is reachable before
responding to the ARP request; ARP request will only be responded if the destination is reachable.
Note: the ARP request matching default route will not use proxy.
Example:
Enabling proxy ARP for VLAN 1.
Switch(Config-if-Vlan1)#ip proxy-arp
