Configuring local proxy ARP

When local proxy ARP is enabled on an IP interface, the 7450 ESS or 7750 SR responds to all ARP requests for IP addresses belonging to the subnet with its own MAC address, and forwards all traffic between hosts in that subnet. Local proxy ARP is disabled by default.

Note: When local-proxy-arp is enabled under a IES or VPRN service, all ICMP redirects on the ports associated with the service are automatically blocked. This prevents users from learning each other's MAC address (from ICMP redirects).

The following example displays a local proxy ARP IES configuration:

A:ALA-A>config>service>ies# info
----------------------------------------------
        interface "test" create
            shutdown
            address 10.10.36.2/24
            local-proxy-arp
        exit
----------------------------------------------
A:ALA-A>config>service>ies#
