EVPN Proxy ARP and ARP Suppression, and Proxy NDP and NDP Suppression

This feature reduces the flooding of ARP and NDP messages in the EVPN network, resulting in a more efficient use of core bandwidth. By default, proxy ARP and ARP suppression and proxy NDP and NDP suppression are enabled. When limiting the number of MAC-IP address bindings that can be learned, the limit can be configured globally or for a specific routing instance, bridge domain, VLAN, or interface. After the specified limit is reached, no additional entries are added to the MAC-IP binding database. You can also specify a timeout interval for MAC-IP address bindings.
