The standards-based election protocol that facilitates redundancy in a LAN environment by eliminating a single point of failure through the use of master and backup routers is Virtual Router Redundancy Protocol (VRRP).
VRRP is a protocol that enables a group of routers to form a virtual router to represent a single IP address. One router in the group is designated as the master router, which is responsible for forwarding packets sent to the virtual IP address. The other routers in the group are backup routers, which monitor the master router and take over its responsibilities if it fails.
VRRP works by having each router in the group participate in an election process to determine which router will be the master router. The router with the highest priority is elected as the master router, and the other routers become backup routers. If the master router fails, one of the backup routers will take over as the new master router.
VRRP eliminates a single point of failure by providing redundancy at the IP layer. If the master router fails, another router in the group can take over without any disruption to the network. This ensures high availability and reduces downtime in LAN environments.
In summary, VRRP is a standards-based election protocol that facilitates redundancy in a LAN environment by eliminating a single point of failure through the use of master and backup routers.
