3.4.3 VRRP: Virtual Router Redundancy Protocol
VRRP is a protocol for allowing automatic failover and redundancy in routers. It creates a “virtual
router,” meaning multiple physical routers can be assigned to one gateway or one host. The main
gateway controls the IP of the virtual gateway and routes packets to virtual IP addresses. If the main
gateway drops, a dynamic failover process elects a new gateway. The IP address of the virtual gateway
can be set as the default gateway for hosts, because it is the first hop. The benefit of using VRRP is
serviceability. The network administrator can avoid the configuration of dynamic routing or routing
discovery protocol on each host. VRRP packet is sent encapsulated in IP packet.
