This chapter covers the following topics, which you need to understand to pass the CCNP/CCDP/CCIP BSCI exam:
Link-state routing protocol overview
OSPF
IS-IS
BGP-4
Convergence
In this chapter, the concepts of routing with IP using the link-state algorithm and the mechanics of the process are dealt with generically as a foundation for the subsequent chapters. Although this chapter compares the routing protocols OSPF, IS-IS, and BGP-4, subsequent chapters deal with each routing protocol individually. The subsequent chapters assume that you comprehend the subjects covered in this chapter.
