Routers are essential gateways, and if one fails, the network can grind to a halt—unless redundancy is in place. This episode explores VRRP (Virtual Router Redundancy Protocol) and other First Hop Redundancy Protocols (FHRPs) that allow multiple routers to share the same virtual IP address. You’ll learn how a “master” router handles active traffic while backups wait to take over seamlessly in the event of failure.We walk through the election process, priority configuration, and preemption
