What happens when the Master in a basic VRRP configuration fails and then comes back online after a period of time?

In a basic Virtual Router Redundancy Protocol (VRRP) configuration, when the Master router fails, one of the Backup routers assumes the Master role to ensure continuity of service. When the original Master comes back online after its failure, it will perform a check to determine if it can reclaim its role.

According to VRRP's design, when the original Master router becomes available again, it attempts to regain its Master status. Since it has a higher priority than the Backup router that was elected as Master during its absence, the original Master will resume its role as the Master. This behavior ensures that the router with the highest priority provides the routing service, maintaining a consistent and optimal network configuration.

Options that suggest the Standby remains the new Master or that a new election occurs do not align with the VRRP specifications regarding the restoration of the original Master. The protocol prioritizes the original Master returning as the leader whenever it comes back online, reflecting the intent behind their configuration and priority settings in VRRP.
