Technical Overview of IGRP

Chapter 9. Distance Vector Protocols: Routing Information Protocol Versions 1 and 2 (RIP-1 and RIP-2)

As IP-based networks enter the 21st century, one of the earliest routing protocols is still present in many modern networks. For good reason, RIP has managed to survive from the creation of IP to the present. This proves one thing about RIP ”despite its limitations, it performs its job well. RIP has evolved over the years from a classful routing protocol, RIP Version 1 (RIP-1), to a classless routing protocol, RIP Version 2 (RIP-2). This chapter covers the operation, configuration, and tuning of RIP-1 and RIP-2, in addition to information on route redistribution.
