VRRP Virtual Router Redundancy Protocol. VRRP specifies an election protocol that
dynamically assigns responsibility for a virtual router to one of the VRRP routers
on a LAN. The VRRP router controlling the IP address(es) associated with a
virtual router is called the master router, and forwards packets sent to these IP
addresses. The election process provides dynamic failover in the forwarding
responsibility should the master router become unavailable. In case the master
router fails, the virtual IP address is mapped to a backup router's IP address; this
backup becomes the master router. This allows any of the virtual router IP
addresses on the LAN to be used as the default first-hop router by end-hosts.
The advantage gained from using VRRP is a higher availability default path
without requiring configuration of dynamic routing or router discovery protocols
on every host. VRRP is defined in RFC 2338.
VRRP router Any router that is running VRRP. A VRRP router can participate in one or more
virtual routers with VRRP; a VRRP router can be a backup router for one or
more master routers.
