This chapter covers the following topics, which you need to understand to pass the CCNP/CCDP/CCIP BSCI exam:
Distance vector routing protocols
RIP version 1 and RIP version 2
IGRP and EIGRP
Choosing between routing protocols using administrative distance
Interior and exterior gateway protocols
The topics in this chapter deal with the original routing protocols and the principles that underlie the technology. These routing protocols are the basis of many subsequent subjects tested in the BSCI exam.
In this chapter, the concepts of routing with IP and the mechanics of the process are dealt with in the context of distance vector routing protocols. The topics will directly reflect questions on the BSCI exam. If you do not understand the contents of this chapter, it will be difficult to follow some of the subsequent subjects, making it difficult to pass the exam.
