Function Brief
Virtual Router Redundancy Protocol,or VRRPfor short, it is proposed
by IETF to solve the routing protocol of single point of failure in the local area
network configuration.It has introduced a standard RFC2338 protocol in
1998. VRRP is widely used in the edge network, It is design intent to support
the IP data traffic failed to transfer in a given case will not cause confusion,
allow the host to use a single router, make the connectivity between routers
is still maintained timely in the case of the failure of the first hop router.
VRRP is a routing fault tolerance protocol, which can also be called
backup routing protocol. A default route is set for all hosts in a local area
network, when the destination address in the network from the host are not
in the network segment, the message will be sent to the external router
through the default route, so that the communication between the host and
the external network is realized. The internal host will not be able to
communicate with the external after the default router down off (port is
closed), If the router set up VRRP, then the virtual router will enable the
backup router at this time,so can achieve the whole network communication.
