“Virtual Router Redundancy Protocol (VRRP) is a simple, yet
robust practice that can provide additional availability in your
network. VRRP can be implemented using Red Hat Enterprise Linux
and/or the VRRPd open source implementations.“VRRP provides gateway redundancy by allowing each router within
the redundant router topology to share a virtual Ethernet MAC
address and a virtual IP address. When the virtual addresses are
active on a particular router, the router is said to be the master.
Routers without control of the virtual addresses are referred to as
backups…”
