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 of Distance Vector Routing and
use the Bellman-Ford algorithm to calculate the routing table.
RIP can update the routing table automatically and find a route to send packet. See the
following figure as an example:
Suppose A supports RIP on WAN1/WAN2, B supports RIP on WAN1 and WAN2, and C
supports RIP on WAN1/WAN2.
B will tell A "if you want to send packets to C, please send it to me first", then A will create
a routing rule to forward packet that destination is C to B.
In another direction, C will do the same thing.
