Introduction
Chapter 6 introduces you to the Cisco Enhanced IGRP routing protocol.
This is a proprietary protocol designed by Cisco for large internetworks.
Chapter 7 introduces the Border Gateway Protocol and the terminology
used with it, as well as when to use and not use BGP in an internetwork.
Chapter 8 continues with our BGP discussion and shows how to configure
BGP with Cisco routers.
Chapter 9 is also a continuation of BGP and demonstrates how to scale
BGP to a large Cisco internetwork, including how to connect to two ISPs.
Chapter 10 ends the book with a detailed discussion on route optimiza-
tion, including redistribution, controlling routing update traffic, and policy-
based routing.
Each chapter ends with review questions that are specifically designed to
help you retain the knowledge presented. To really nail down your skills,
read each question carefully, and, if possible, work through the hands-on
labs in some of the chapters.
