ARP Proxy
The Proxy ARP technique is used by the device on a given IP subnet to answer
ARP queries for a network address that is not on that network.
NOTE
The ARP proxy feature is only available when the device is in L3 mode.
The ARP Proxy is aware of the destination of traffic, and offers another MAC
address in reply. Serving as an ARP Proxy for another host effectively directs LAN
traffic destination to the host. The captured traffic is then typically routed by the
Proxy to the intended destination by using another interface, or by using a tunnel.
The process in which an ARP-query-request for a different IP address, for proxy
purposes, results in the node responding with its own MAC address is sometimes
referred to as publishing.
To enable ARP Proxy on all IP interfaces:
STEP 1
Click
IP Configuration
>
IPv4 Management and Interfaces
>
ARP Proxy
.
STEP 2
Select
ARP Proxy
to enable the device to respond to ARP requests for remotely-
located nodes with the device MAC address.
STEP 3
Click
Apply
. The ARP proxy is enabled, and the Running Configuration file is
updated.
