This feature is used to send gratuitous ARPs and NDs to update the mac address in neighbors’ mac address table when the users configure to change the mac address in the routed interface.

This feature is adding VARP support for proxy ARP and local proxy ARP. Without this feature, when an active VARP instance and proxy ARP / local proxy ARP are both configured on the same interface, proxy ARP / local proxy ARP uses the interface physical MAC address in the proxy ARP / local proxy Arp replies. With this feature, when an active VARP instance and proxy ARP / local proxy ARP are both configured on the same interface, proxy ARP / local proxy ARP uses the VARP virtual MAC address in the proxy ARP / local proxy Arp replies.

This feature is used to add VRRP support for local-proxy-arp. Previously, when both ip local-proxy-arp and a VRRP virtual mac address were configured on the same router, when the router received an ARP request with an IP address within the same subnet as the router, the router replied with the physical mac address, while the expected behavior is to reply with the virtual mac address for the ARP sender MAC, while for Ethernet Source MAC, using virtual mac address for VRRP v2, using physical mac address for VRRP v3. This feature is designed to fill this gap.
