5.2.2.4 VRRP
A VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol aimed to
eliminate the single point of failure by automatically assigning available IP routers to
participating hosts. Using a virtual router ID (VRID) address and virtual router IP (VRIP)
address to represent itself, a virtual router consists of two or more physical routers, including
one master router and one or more backup routers. All routers in the virtual router group
share the same VRID and VRIP. The master router provides primary routing and the backup
routers monitor the status of the master router and become active if the master router fails.
