Chapter 18 IP Configuration 178
In VRRP, a virtual router (VR) represents a number of physical layer-3 devices. An IP address
is associated with the virtual router. A layer-3 device having the same IP address is the
preferred master router while the other Layer-3 devices are the backup routers. The master
router forwards traffic for the virtual router. When the master router becomes unavailable, a
backup router assumes the role of the master router until the master router comes back up and
takes over.
