Chapter 1 Overview
VRRP (Virtual Router Redundancy Protocol) is a fault-tolerant protocol. VRRP
protocol can help to constitute a router backup group in a LAN, the VRRP
router is equivalent to a virtual router. A host in LAN only need to know this
virtual router’s IP address and doesn’t need to know the IP address of the
specific router. When set the host’s default gateway as the virtual router’s
virtual IP address, host can use the virtual gateway to communicate with the
external network.

Center unit.
