This feature is only supported on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.
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 as follows:
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, see the 7210 SAS-D, Dxp, K 2F1C2T Routing Protocols Guide and 7210 SAS-K 2F6C4T, K 3SFP+ 8C Routing Protocols Guide.
Apply the policy statement to the proxy-arp configuration in the config>router>interface context.
