VRRP Configuration
The Virtual Router Redundancy Protocol (VRRP) is an Internet protocol that provides the
backup router operation method in a LAN. If a fault occurs with a router that transmits a
packet from a host in a LAN, decide a virtual IP address in a DHCP manually or by default
by using a virtual router fault recovery protocol and share it among routers. Once a primary
router and a backup router are decided, the backup router becomes a primary router when a
fault occurs with the primary router.
