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.
