Explanation
In Active-Passive high availability (HA) mode, the active unit is responsible for handling traffic while the passive unit remains idle, ready to take over in case of a failure. When a failover occurs, the active unit sends out gratuitous ARP messages to notify neighboring devices about the change in the active unit's IP address. This ensures that the network devices update their ARP tables and can forward traffic to the new active unit.
