Overview

VRRP(Virtual Router Redundancy Protocol), defined in RFC3768, allows multiple systems on a network to share an IP address between them. Each node sends out a broadcast packet detailing the VRRP group it is participating in and its priority. The highest priority node wins the election. After a node wins three elections, it assumes the role of master and takes the IP and MAC address being shared.
