VRRP

VRRP provides for automatic assignment of available routers to participating hosts. This
increases the availability and reliability of routing paths via automatic default gateway
selections on a LAN.
The protocol achieves this by creating virtual routers, comprised of master and backup
routers. VRRP routers use multicast to notify its presence in the LAN (never forwarding
outside of the LAN).
VRRP is based on RFC 2338 and RFC 3768.
