What is RIP (Routing Information Protocol) in Networking?

RIP (Routing Information Protocol) is a Distance Vector routing protocol commonly used in ancient times.

What is RIP Protocol?

The RIP routing protocol is defined in RFC 1058. It sends the routing table from the active interfaces every 30 seconds and also uses Hop Count. Its maximum Hop Count is 15, and the 16 is considered unreachable.

It works very well in small networks. However, it is not recommended for use on extensive networks.

How Does It Work?

When a router receives a modified routing table, it first updates its routing table to notify the other Routers of the change.

If the router learns a new route from another router, it increases the number of routes before adding the new route to its routing table.

When the router updates its routing table, it uses Triggered Updates to forward this change to other routers.

The RIP protocol is simple and easy to use in a small network. It is the most widely used routing protocol because of its simplicity and ease of use.

Disadvantages

1. Allows up to 15 hops.
2. Regularly sends a copy of the entire routing table to neighboring routers that are directly connected.
3. Increases routing table network traffic.
4. In an extensive network, integration becomes very slow in a network change.

What are the RIP Protocol Versions?

1. Version 1
2. Version 2

Version 1

Version 1 uses classful routing. For class routing, all network devices must be on the same network. RIPv1 does not send subnet mask information in the routing table update.

Version 2

Version 2 uses classless routing. In the routing table update, the subnet can send mask information.

The significant difference between the RIP1 and RIP2 versions is that V1 does not send subnet mask information in route updates, but V2 sends subnet mask information.
