The Routing Information Protocol (RIP) is a dynamic routing protocol used in local
and wide area networks. The routing information packet will be sent out by web server
or router periodically, and can be used to communicate with other routers. It will
calculate the number of network nodes on the route to ensure there is no obstruction
on the network routine. In addition, it will choose a correct route based on the method

routing table.
RIP can update the routing table automatically and find a route to send packet. See the
following figure as an example:
