Configuring Proxy ARP

To configure proxy ARP, you can configure:

A prefix list in the

config>router>policy-options>prefix-list

context.

A route policy statement in the

config>router>policy-options>policy-

statement

context and apply the specified prefix list.

→ In the policy statement

entry>to

context, specify the host source address(es) for

which ARP requests can or cannot be forwarded to non-local networks, depending on
the specified action.

→ In the policy statement

entry>from

context, specify network prefixes that ARP

requests will or will not be forwarded to depending on the action if a match is found.
For more information about route policies, refer to

Route Policies on page 597

.

Apply the policy statement to the proxy-arp configuration in the

config>router>interface

context.

CLI Syntax:

config>router# policy-options

begin

commit

prefix-list name

prefix ip-prefix/mask [exact|longer|through

length|prefix-length-range length1-length2]

The following example displays prefix list configuration command usage. These commands are
configured in the

config>router

context.

Example:config>router>policy-options# begin

config>router>policy-options# prefix-list prefixlist1

config>router>policy-options>prefix-list# prefix 10.20.30.0/24

through 32

config>router>policy-options>prefix-list# exit

config>router>policy-options# prefix-list prefixlist2

config>router>policy-options>prefix-list# prefix 10.10.10.0/24

through 32

config>router>policy-options>prefix-list# exit

config>router>policy-options# commit
