<p>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.</p><p>We walk through the election process, priority configuration, and preemption settings that determine which router takes the lead. These protocols are vital for enterprise networks that require uninterrupted gateway access. Whether you're building a resilient core network or preparing for exam scenarios involving router failure, this episode teaches you how virtual gateways provide true fault tolerance.</p>
