A routing protocol describes the rules that must be followed by a router while it interacts with neighboring routers to learn the path and to maintain the network in the routing tables.
The principal difference is that RIP falls in the category of distance vector routing protocol whereas OSPF is the example of link state routing.
IGP Interior gateway routing protocol is restricted to an autonomous system, which means all routers operates inside an autonomous system. On the other hand, EGP exterior gateway routing protocol works for the two autonomous system means from one autonomous system to another and vice-versa. An autonomous system is a logical boundary that represents a network which works under a single common administration.
Routing Information Protocol is the straight implementation of distance vector routing for local networks. In every 30 seconds, it delivers an entire routing table to all active interfaces. Hop count is the only metrics to describe the best path to a remote network, but it can be 15 at max. It prevents routing loops, through restricting the number of hop counts permitted in the path.
Convergence is a process of collecting the topological information or updating the information for the other routers through the implemented routing protocol. Convergence occurs when the router is transitioned from either to forwarding or blocking states, and it prevents data forwarding at that instant. The main issue with convergence is the time it takes to update information in a device.
Slow convergence can result in inconsistent routing table and routing loops. RIP determines optimal route for the packet to reach destination by hop count. Let us see how RIP works.
In RIP participant routers are classified as active and passive. Active router sends its routing table to the others and listens for their updates. Passive router listens for updates from other participants but does not propagate its own routing entries.
RIP router broadcasts update message once in 30 seconds. RIP works best when the network is in equilibrium condition and will have problem as the network grows and will have to wait for long to build the table. Few find the former to be perfect for their router whereas the others take the latter into consideration. Make much out of it by using the right one for your networks!

All the routing protocols work with a similar procedure and let us take a closer look at it now. As soon as a transmission is to be handled, a routing protocol first analyzes the possible routes for the transmission to happen.
There might be only one route or many routes based on the network in which the only designed to device or computer is present. The next step is to determine the best possible route from the available list of routes that have been determined earlier.
The routing protocols not only identify only one best but also pick the next-next better choices as well. Those choices are useful when the best route is not available at present or if there is more traffic on that particular route.
Now the actual transmission takes place with the help of the already identified route combinations. What is RIP? What is OSPF? The router that uses OSPF first sends certain routing information to and forth between them.
They never send the entire routing table instead they just send only the necessary routing information to carry out the transmissions. It is a kind of link state protocol and is out of the scope of our discussion here. We should keep in mind that the OSPF is a better one to find the shortest routing paths between devices in a network. Later, the router consolidated that information and constructs its own routing table. This table is sent to those neighboring devices at a regular interval of time and the consolidated routing table of the router is updated.
