The most positive thing that I can say about 2002 is that I am glad it is over. While I cannot complain about the past year, too many people I know were unemployed or just barely getting by. The IT industry did not have its best year. Layoffs in the IT sector reached somewhere around 1 million, and IT budgets were way down. Cisco has had a relatively good year all things considered. It held on to its market share in core technologies and built up business in new sectors, laying the groundwork for diversification.

Although networking infrastructure elements—particularly industrial-strength routers and switches—remain the heart and soul of Cisco's primary business, the company is also moving with great force and vigor into the area sometimes called Voice over IP (VoIP), also known as IP Telephony. Whatever you call it (and Cisco's fond of both terms among the language it uses to describe its IP-based voice products and solutions), Cisco expects this niche to become another of its primary business mainstays and is forecasting $7 billion in related business for 2004, with expectations of easily reaching double-digit billions in 2005.

As a designer, content networking technologies allows you to intelligently distribute content throughout the network, thereby reducing WAN bandwidth requirements. For example, a user could open a web browser and point to a particular site. A content networking component, called a "cache engine," might already have that site's content stored locally. Therefore, the cache engine satisfies the user's web request locally, without burdening the WAN.

This chapter reviews distance-vector routing protocols. It covers both versions of the Routing Information Protocol (RIP). It also discusses the Cisco Interior Gateway Routing Protocol (IGRP) and Enhanced Interior Gateway Routing Protocol (EIGRP).

The questions in the following quiz are designed to help you gauge how well you know the material covered in this chapter. Compare your answers with those found in Appendix A, "Answers to Quiz Questions." If you answer most or all of the questions thoroughly and correctly, you might want to skim the chapter and proceed to the "Q&A" and "Case Studies" sections at the end of the chapter. If you find you need to review only certain subject matter, search the chapter for only those sections that cover the objectives you need to review and then test yourself with those question again, as well as the "Q&A" and "Case Studies" questions. If you find the following questions too difficult, read the chapter carefully until you feel you can easily answers these and the "Q&A" and "Case Studies" questions.
