What is RIP?

Rating:

RIP stands for Routing Information Protocol. This protocol is used for updating the routing information available with routers. The updates occur at specific time intervals, when a router wishes to send its update to the adjoining routers, or when the network topology changes. RIP measures the distance between the source and the destination in terms of hop-counts. Each intermediate node between the source and the destination is given a hop-count value of one. Suppose there are four intermediate nodes between the source and the destination, then the hop-count value that the source uses to send packets to the destination is five. As the packet arrives at each intermediate node, the hop-count value decreases by one. This continues, until the packet reaches the destination node, where the hop-count value becomes zero. If a new node is added between the source and the destination, the hop-count value increases by one. RIP prefers the path between the source and the destination having the least hop-count value.
