Configuring proxy ARP

To configure proxy ARP, you can configure the following:

config>router# policy-options
    begin
        commit
        prefix-list name
            prefix ip-prefix/mask [exact | longer | through
            length | prefix-length-range length1-length2]

Use the following syntax to configure the policy statement specified in the proxy-arp-policy policy-statement command.

config>router# policy-options
        begin
        commit
        policy-statement name
            default-action {accept | next-entry | next-policy | reject}
            entry entry-id
                action {accept | next-entry | next-policy | reject}
                to
                    prefix-list name [name...(upto 5 max)]
                from
                    — prefix-list name [name...(upto 5 max)]
Example

The following is a sample prefix list and policy statement configuration output.

A:ALA-49>config>router>policy-options# info
----------------------------------------------
     prefix-list "prefixlist1"
          prefix 10.20.30.0/24 through 32
     exit
     prefix-list "prefixlist2"
          prefix 10.10.10.0/24 through 32
     exit
...
     policy-statement "ProxyARPpolicy"
          entry 10
               from
                    prefix-list "prefixlist1"
               exit
               to
                    prefix-list "prefixlist2"
               exit
               action reject
          exit
          default-action accept
          exit
     exit
...
----------------------------------------------
A:ALA-49>config>router>policy-options#

Use the following syntax to configure proxy ARP.

config>router>interface interface-name
    local-proxy-arp
    proxy-arp-policy policy-name [policy-name...(upto 5 max)]
    remote-proxy-arp
Example

The following is a sample proxy ARP configuration output.

A:ALA-49>config>router>if# info
----------------------------------------------
     address 192.0.2.59/24
     local-proxy-arp
     proxy-arp
          policy-statement "ProxyARPpolicy"
     exit
