ip proxy-arp
<address> <subnet mask>
Use the
ip proxy-arp
command to enable proxy Address Resolution Protocol (ARP) on the interface. Use
the
no
form of this command to disable this feature.
Syntax Description
<address>
Defines the IP address for the interface in dotted decimal notation (for example:
192.168.73.101).
<subnet mask>
Specifies the subnet mask that corresponds to the listed IP address.
Default Values
By default, proxy ARP is enabled.
Functional Notes
In general, the principle of proxy ARP allows a router to insert its IP address in the source IP address field
of a packet (if the packet is from a host on one of its subnetworks). This allows hosts to reach devices on
other subnetworks without implementing routing or specifying a default gateway.
If proxy ARP is enabled, the SROS will respond to all proxy ARP requests with its specified MAC address
and forward packets accordingly.
Enabling proxy ARP on an interface may introduce unnecessary ARP traffic on the network.
Usage Examples
The following enables proxy ARP on the loopback interface:
ProCurve(config)#
interface loopback 1
ProCurve(config-loop 1)#
ip proxy-arp
