FHRP
First Hop Redundancy Protocol (FHRP) aims to provide high availability and fault tolerance for the default gateway in a computer network. Specialized protocols like HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), and GLBP (Gateway Load Balancing Protocol) are commonly used under the FHRP umbrella. These protocols facilitate a seamless transition in the case of gateway failure, thus ensuring continued network service.
