The vpp stack will answer ARP requests for the indicated address range. Multiple proxy-arp ranges may be provisioned. @note Proxy ARP as a technology is infamous for blackholing traffic. Also, the underlying implementation has not been performance-tuned. Avoid creating an unnecessarily large set of ranges. To enable proxy arp on a range of addresses, use: .. code-block:: console set ip arp proxy 6.0.0.1 - 6.0.0.11 Append 'del' to delete a range of proxy ARP addresses: .. code-block:: console set ip arp proxy 6.0.0.1 - 6.0.0.11 del You must then specifically enable proxy arp on individual interfaces: .. code-block:: console set interface proxy-arp GigabitEthernet0/8/0 enable To disable proxy arp on an individual interface: .. code-block:: console set interface proxy-arp GigabitEthernet0/8/0 disable Declaration: ``set_int_proxy_enable_command`` `src/vnet/arp/arp_proxy.c line 246 `_ Implementation: ``set_int_proxy_arp_command_fn`` show arp proxy ------------------------------------------------------------------------- .. code-block:: console show ip arp Display all the IPv4 ARP proxy entries.
