The difference between RIP, IGRP and EIGRP

Our expert, Sudhanshu Gupta, goes over the differences between RIP, IGRP and EIGRP, in this explanation.

What is the difference between RIP, IGRP and EIGRP?

RIP, IGRP and EIGRP are different routing protocols. RIP stands for Routing Information Protocol; IGRP stands for Interior Gateway Routing Protocol; and EIGRP stands for Enhanced IGRP.

The main difference being RIP and IGRP are distance vector protocols; EIGRP is more of link state protocol. Then there is a difference in their operations, times (like updates, refreshes, etc.), how they keep track of routing tables, etc. I talk more about routing protocol's different routing tables in this expert response.

You can find a lot of information off the Internet for these protocols. I would suggest you to check it out on cisco.com, and let me know if you have any specific queries on these protocols.
