- RIP- Routing Information Protocol.
- RIP is dynamic routing protocol that uses hop count as a routing metric to find the best path between the designation and the source network.
- It works on the network layer of the OSI model and a distance-vector routing protocol that has an AD value of 120.
- Routing Information Protocol uses port number 250.
- It updates of the network are exchanged periodically and routing information are always broadcast.
- Routers always trust routing information received from neighbor routers; hence it is known as Routing on
- There are three types of version routing information protocol they are, RIP version1, RIP version2, RIPng.
- RIP Version1 is also known as classful routing protocol because it doesn’t support authentication of updated messages.
- RIP Version2 is also known as classless routing protocol it sends information of subnet mask in its routing update.
- RIPng is classless updates are sent.
