What is FHRP?

FHRP stands for First Hop Redundancy Protocol. It is a class of protocols that provide high availability and redundancy for network gateways. These protocols allow multiple routers to share a virtual IP address and MAC address, ensuring that if the active router fails, a standby router can seamlessly take over without disrupting network connectivity. Common examples include VRRP, HSRP, and GLBP.
