VRRP
VRRP (Virtual Router Redundancy Protocol) is a fault-tolerant protocol. Generally, all hosts in a
LAN (Local Area Network) would set a default route. Packets which are sent by the host and
whose destination address does not belong to the local network segment will be sent to the
gateway via the default route. Therefore, communication between the host and external
network can be established. Once the gateway fails, all hosts of this network segment whose
default next hop is the gateway will stop communicating with external network.
