Virtual Router Redundancy Protocol (VRRP) is used to provide fast-fail over for hosts if the default gateway fails. This eliminates the single point of failure inherent in a network with statically configured default routes. The VRRP protocol defines an election process that will determine a Master and a Backup router. The Master router will forward all packets destined for the IP Address associated with the virtual router. The Backup router monitors the availability of the Master router and will assume Mastership in the event that the Master router fails.
The VRRP protocol is described in detail in RFC 2338.
