Virtual Router Redundancy Protocol
VRRP is a protocol, which allows several routers on a multi-access link to utilize the same virtual IP/MAC address. One router will be elected as a master with the other routers acting as backups. All routers participating in VRRP will share each other's IP/MAC information. Should one of the routers fail, immediate fail over to another active router will occur. The main benefit of using VRRP is that host systems (i.e. PC's) may be configured with a single default gateway and fail over time is at most only several seconds thus there is no effect on the IP Hosts or the applications that they are running. Additionally, VRRP supports load sharing of traffic when Default Gateways are configured appropriately. Utilizing VRRP guarantees network availability.
