Usage Guidelines
Learning gratuitous ARP enables Layer 3 devices to learn ARP entries from incoming gratuitous ARP packets from the hosts which are directly connected. This help achieve faster convergence for the hosts when they are ready to send traffic.
A new ARP entry is created when a gratuitous ARP packet is received. If the ARP is already existing, it will be updated with the new content.
The
no form of the command disables learning gratuitous ARP.
