Routing Information Protocol • Routing Information Protocol (RIP) is a distance vector routing protocol that is used in thousands of networks throughout the world. • Initially specified in RFC 1058 • Is a distance vector routing protocol • Uses hop count as the metric for path selection • Defines a hop count greater than 15 as an unreachable route • Sends routing table contents every 30 seconds, by default
Routing Information Protocol • When a router receives a routing update that includes a new or changed route, the router updates its routing table to reflect this new route. • At each router, the hop count value is increased by one. • The router uses the local network address of the directly connected router which sent the update as the next hop address.
Routing Information Protocol • After updating its routing table, the router immediately begins transmitting routing updates in order to inform other network routers of the change. • These updates, called triggered updates, are sent independently of the regularly scheduled updates that RIP routers forward.
Routing Information Protocol • The RIP protocol is simple, easy to implement, and is available free of cost with most routers. • These advantages make RIP a widely used and popular routing protocol.
RIP has several disadvantages: • Allows a maximum of 15 hops, so it can only be used for networks that connect no more than 16 routers in series. • Periodically sends complete copies of the entire routing table to directly connected neighbors. In a large network, this can cause a significant amount of network traffic each time there is an update. • Converges slowly on larger networks, when the network changes.
