What routers does VRRP employ in its setup?

In Virtual Router Redundancy Protocol (VRRP) setups, the terminology used to identify the roles of routers is "Master" and "Backup." The Master router is responsible for forwarding packets and handling traffic for the virtual IP address that VRRP manages, while Backup routers are on standby to take over if the Master fails. This redundancy ensures high availability and reliability in network routing.

The Master router takes on the primary role, actively directing traffic, while all Backup routers monitor the state of the Master. If the Master becomes unavailable—due to a failure or link loss—a Backup router will take over its responsibilities and become the new Master, ensuring continuity of service without manual intervention.

This hierarchical structure is vital for network resilience and minimizes disruption in cases of failures. Thus, the designation of routers within a VRRP setup distinctly emphasizes the active role of the Master and the support role of the Backup, which is captured by the correct choice.
