This section provides a brief insight into the contents of the book, the major goals, and some of the book features that you will encounter when using this book.
This book contains nine major parts, which correspond to, and are in the same order as, the last nine major headings in the 10-heading CCIE Routing and Switching written blueprint. The topics under the first heading of the blueprint, "General Networking Theory," are covered in this book, but they are spread throughout the various parts of the book.
Each part of the book has one or more chapters. Some have a single chapter, such as Part VII, "Security." However, Part III, "IP Routing," has six chapters and a high page count.
Beyond the chapters in the nine major parts of the book, you will find several useful appendixes gathered in Part X. In particular, Appendix C, "CCIE Routing and Switching Exam Updates: Version 1.0," as mentioned earlier, will be updated with subsequent versions online at http:// www.ciscopress.com/title/9781587201967 when appropriate to provide you with the most up-to-date material. Also included in Part X is a decimal to binary conversion chart for reference in Appendix B. There are also several useful appendixes that can only be accessed from the CD in the back of the book.
Following is a description of each part's coverage:
■ Part I, "LAN Switching" (Chapters 1-3)
This part focuses on LAN Layer 2 features, specifically Ethernet (Chapter 1), VLANs and trunking (Chapter 2), and Spanning Tree Protocol (Chapter 3).
This part is titled "IP" to match the blueprint, but it might be better titled "TCP/IP" because it covers details across the spectrum of the TCP/IP protocol stack. It includes IP addressing (Chapter 4) and IP services such as DHCP and ARP (Chapter 5).
■ Part III, "IP Routing" (Chapters 6-11)
This part covers some of the more important topics on the exam and is easily the largest part of the book. It covers Layer 3 forwarding concepts (Chapter 6), followed by three routing protocol chapters, one each about RIP, EIGRP, and OSPF (Chapters 7 through 9, respectively). Following that, Chapter 10 covers route redistribution between IGPs. At the end, Chapter 11 hits the details of BGP.
This part covers the more popular QoS tools, including some MQC-based tools, as well as several older tools, particularly FRTS. The chapters include coverage of classification and marking (Chapter 12), queuing and congestion avoidance (Chapter 13), plus shaping, policing, and link efficiency (Chapter 14).
■ Part V, "Wide-Area Networks" (Chapter 15)
The WAN coverage has generally shrunk with the last several changes to the CCIE Routing and Switching written blueprints, so Frame Relay is all that remains in this section. However, the latest blueprint revision includes another WAN topic, MPLS, which is covered in Chapter 19. MPLS is covered in Part VIII of this book to keep the order of book parts in synch with the blueprint.
■ Part VI, "IP Multicast" (Chapters 16-17)
This is one of the two parts of the book that cover topics that are mostly ignored for the CCNP exam. As a result, the text assumes that the reader has no knowledge of multicast before beginning this part. Chapter 16 covers multicast on LANs, including IGMP and how hosts join multicast groups. Chapter 17 covers multicast WAN topics.
Key ■ Part VII, "Security" (Chapter 18) , Topic
Given the CCIE tracks for both Security and Voice, Cisco has a small dilemma regarding whether to cover those topics on CCIE Routing and Switching, and if so, in how much detail. This part covers a variety of security topics appropriate for CCIE Routing and Switching, in a single chapter. This chapter focuses on switch and router security. (Note that Voice, whose protocols were formerly covered on CCIE Routing and Switching, is not covered in the current blueprint or in this book.)
As mentioned in the WAN section, MPLS is an addition to the latest blueprint and thus debuts with its own chapter. As with many larger topics in this book, the blueprint does not cover all parts of MPLS but rather focuses on enterprise-related topics such as core MPLS concepts and MPLS VPNs.
IPv6 is comprehensively addressed in the version 3.0 exam blueprint, so we've added a fairly lengthy chapter to cover it.
— Appendix A, "Answers to the 'Do I Know This Already?' Quizzes"
This appendix lists answers and explanations for the questions at the beginning of each chapter.
This appendix lists the decimal values 0 through 255, with their binary equivalents.
— Appendix C, "CCIE Routing and Switching Exam Updates: Version 1.0"
As of the first printing of the book, this appendix contains only a few words that reference the web page for this book at http://www.ciscopress.com/title/ 9781587201967. As the blueprint evolves over time, the authors will post new materials at the website. Any future printings of the book will include the latest newly added materials in printed form inside Appendix C.
NOTE Appendixes D through H are in printable, PDF format on the CD.
— (CD-only) Appendix D, "IP Addressing Practice"
This appendix lists several practice problems for IP subnetting and finding summary routes. The explanations to the answers use the shortcuts described in the book.
— (CD-only) Appendix E, "Key Tables for CCIE Study"
This appendix lists the most important tables from the core chapters of the book. The tables have much of the content removed so you can use them as an exercise. You can print the PDF and then fill in the table from memory, checking your answers against the completed tables in Appendix F.
— (CD-only) Appendix F, "Solutions for Key Tables for CCIE Study"
This appendix lists the completed tables from the Appendix E exercises so you can check your answers.
— (CD-only) Appendix G, "IEEE 802.11 Fundamentals"
Because wireless was removed from the version 3.0 blueprint, we've removed the two wireless chapters from the third edition of this book. However, there's a chance that wireless will return to the CCIE Routing and Switching blueprint in the future, so we're including those chapters as appendixes on the CD.
— (CD-only) Appendix H, "Wireless LAN Solutions"
Like Appendix G, Appendix H covers wireless materials that may be useful for future CCIE Routing and Switching study, if the blueprint is revised to once again include wireless coverage.
NOTE There is also a glossary near the end of the book. You can use it to look up key terms and to find the definitions for the exercise at the end of each chapter.
The core chapters of this book have several features that help you make the best use of your time:
■ "Do I Know This Already?" Quizzes—Each chapter begins with a quiz that helps you to determine the amount of time you need to spend studying that chapter. If you score yourself strictly, and you miss only one question, then you may want to skip the core of the chapter and move on to the "Foundation Summary" section at the end of the chapter, which lets you review facts and spend time on other topics. If you miss more than one, you may want to spend some time reading the chapter or at least reading sections that cover topics about which you know you are weaker.
■ Foundation Topics—These are the core sections of each chapter. They explain the protocols, concepts, and configuration for the topics in that chapter.
■ Foundation Summary—The "Foundation Summary" section of this book departs from the typical features of the "Foundation Summary" section of other Cisco Press Exam Certification Guides. This section does not repeat any details from the "Foundation Topics" section; instead, it simply summarizes and lists facts related to the chapter but for which a longer or more detailed explanation is not warranted.
■ Key Topics—Throughout the "Foundation Topics" section, a Key Topic icon has been placed beside the most important areas for review. After reading a chapter, when doing your final preparation for the exam, take the time to flip through the chapters, looking for the Key Topic icons, and review those paragraphs, tables, figures, and lists.
■ Fill in Key Tables from Memory—The more important tables from the chapters have been copied to PDF files available on the CD as Appendix E. The tables have most of the information removed. After printing these mostly empty tables, you can use them to improve your memory of the facts in the table by trying to fill them out. This tool should be useful for memorizing key facts. CD-only Appendix F contains the completed tables so you can check your work.
■ CD-based practice exam—The companion CD contains multiple-choice questions and a testing engine. The CD includes 300 questions unique to the CD. As part of your final preparation, you should practice with these questions to help you get used to the exam-taking process, as well as help refine and prove your knowledge of the exam topics.
■ Key Terms and Glossary—The more important terms mentioned in each chapter are listed at the end of each chapter under the heading "Definitions." The glossary, found at the end of the book, lists all the terms from the chapters. When studying each chapter, you should review the key terms, and for those terms about which you are unsure of the definition, you can review the short definitions from the glossary.
■ Further Reading—Each chapter includes a suggested set of books and websites for additional study on the same topics covered in that chapter. Often, these references will be useful tools for preparation for the CCIE Routing and Switching lab exam.
