    Gratuitous ARP is an announcement or message for updating other hosts’ mapping of a hardware address when the sender’s IP address or MAC address has changed. The gratuitous ARP message is usually broadcast as an ARP request containing the sender’s protocol address (SPA) in the target field (TPA=SPA) and the target hardware address (THA) set to zero. Send, clear, ignore and spoof ARP. Know how to truly disable the processing of gratuitous ARP in a Cisco router.

    ARP and RARP, proxy arp, gratuitous arp

    Most hosts on a network will send out a Gratuitous ARP when they are initialising their IP stack. This Gratuitous ARP is an ARP request for their own IP address and is used to check for a duplicate IP address. If there is a duplicate address then the stack does not complete initialisation. ARP was developed in the early 1980s as a general-purpose address translation protocol for IP networks. Besides Ethernet and Wi-Fi, ARP has been implemented for ATM, Token Ring, and other physical network types. I have a Windows 2003 server in our Domain that has an Intel SE7210TP1-E motherboard. I ran Wireshark on our network via a mirrored port on one of our 3com 3300 switches, and I got a ton of “Gratuitous Arp” requests from the server’s IP address.

However, Proxy Gratuitous ARP Requests are not sent on VLAN interfaces during such a failover. This eventually causes the hosts on the internal network to be unreachable. Gratuitous ARP Requests can be seen in tcpdump only on the physical interfaces, but not on VLAN interfaces.
