Virtual routing redundancy Protocol (Virtual Router Redundancy Protocol, referred to as VRRP) is a routing protocol proposed by IETF to solve the single point of failure of static gateways in LAN. In 1998, a formal RFC2338 protocol standard was introduced. VRRP is widely used in edge networks, and its design goal is to support the failure of IP data traffic under certain circumstances without confusion, to allow hosts to use a single router, and to maintain connectivity between routers even if the actual first hop router fails.
