First Hop Redundancy Protocol (FHRP) is a network protocol that provides redundancy for the default gateway in a subnet by allowing multiple routers to work together to maintain network connectivity in case of a failure.
First Hop Redundancy Protocol Definition: First Hop Redundancy Protocol (FHRP) is a network protocol that provides redundancy for the default gateway in a subnet by allowing multiple routers to work together to maintain network connectivity in case of a failure.
First Hop Redundancy Protocol (FHRP) is a network protocol used to provide high availability and fault tolerance for network devices, specifically in routing environments. FHRP enables multiple routers to work together in a group, with one router designated as the active router and the others as standby routers. In the event of a failure on the active router, one of the standby routers seamlessly takes over to ensure continuous network operation without disruption. Common FHRP protocols include HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), and GLBP (Gateway Load Balancing Protocol).
