Specifically, this book covers the second of iv courses. To be successful in this course and achieve your CCNA certification, you should do everything possible to arm yourself with a variety of tools and training materials to support your learning efforts. This book is just such a collection of tools. Used to its fullest extent, it can help you gain the fellowship as healthy as practice the skills associated with the sate area of the CCNA 2 Routers and Routing Basics course.Specifically, this book can help you work on these main areas of CCNA 2 Configuring a router Managing the Cisco IOS Selecting a routing protocol Verifying and troubleshooting a network Implemen ting basic security with vex control lists Books similar to this one are similarly available for the other cardinal courses Networking Basics CCNA 1 Labs and Study Guide, Switching Basics and Intermediate Routing CCNA 3 Labs and Study Guide, and WAN Technologies CCNA 4 Labs and Study Guide. Goals and Methods One of the most great goals of this book is to help you prepare for either the CCNA exam (640-801) or the presentment exam (640-821).Whether you are studying for the full exam or the first part of your CCNA, passing either of these exams means that you not only have the required knowledge of the technologies cover by the exam, but that you can also plan, design, implement, operate, and troubleshoot these technologies. In other words, these exams are rigorously application-based. In fact, if you view the main objectives for the CCNA exam at http//www. cisco. com/go/certifications, you can see the following four categories of objectives Planning & Design Implementation & Op eration Troubleshooting TechnologyAlthough Technology is listed last, a CCNA student cannot possibly plan, design, implement, operate, and troubleshoot networks without first fully grasping the technology. So you moldiness devote large amounts of time and effort in the Study Guide sectionalization of each chapter, learning the concepts and theories before applying them in the Lab Exercises. The Study Guide section offers exercises that help you learn the concepts and configurations that are crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes some or all of the following types of exercises Vocabulary Matching and Completion Skill-Building Activities and Scenarios Configuration Scenarios Concept Questions Journal Entries Internet Research xxx Routers and Routing Basics CCNA 2 Labs and Study Guide The Lab Exercises section includes a Command Reference table, all the online Curriculum Labs, and new Comprehensive Labs and Challenge L abs. The Curriculum Labs typically pass you through the configuration tasks tincture by step. The Comprehensive Labs include many, if not all, of the configuration tasks of the Curriculum Labs without actually providing you with the commands.The Challenge Labs take this a step further, often giving you only a general requirement that you must implement fully without the details of each small step. In other words, you must use the knowledge and skills you gained in the Curriculum Labs to successfully complete the Comprehensive and Challenge Labs. In fact, you should not attempt the Comprehensive or Challenge labs until you have worked through all the Study Guide activities and the Curriculum Labs. Avoid the temptation to work through the Comprehensive and Challenge Labs by flipping back through the Curriculum Labs when you are unsure of a command.Do not try to short-change your CCNA training. You need a deep understand of CCNA knowledge and skills to ultimately be successful on th e CCNA exam. How This Book Is Organized Because the inwardness of Routers and Routing Basics CCNA 2 Companion Guide and the online course is sequential, you should work through this book in order, beginning with Chapter 1. Chapters 1 through 11 cover the following proceedss Chapter 1, WANs and RoutersAfter presenting a few vocabulary exercises covering the topic of WANs, this chapter delves into the internal and external components of routers.Understanding how a router works and how you connect to a router are important concepts and skills you need throughout the rest of your CCNA studies. The three Curriculum Labs centralize your tutelage on connecting LANs and WANs using routers. An supererogatory Challenge Lab helps you review the skills knowledgeable in the Curriculum Labs. Chapter 2, Introduction to RoutersThis chapter discusses the basics of using the command-line interface (CLI). Several exercises help you solidify your skills with using the CLI.In addition, you work th rough exercises that heighten on understanding the router boot sequence and interpreting output from the show version command. The three Curriculum Labs focus your management on the configuration tasks cover in the chapter. Two additional labs, a Comprehensive Lab and Challenge Lab, help you review the commands and skills intentional in the Curriculum Labs. Chapter 3, Configuring a RouterThis chapter first focuses on basic router configuraion, including learning the commands that every router uses as well as activating interfaces and setting up basic routing. past your attention turns to file-management issues okay up the configuration and the IOS. The ten Curriculum Labs focus your attention on the router configuration and file-management tasks cover in the chapter. Two additional labs, a Comprehensive Lab and Challenge Lab, help you review the commands and skills learned in the Curriculum Labs. Chapter 4, Learning About Other DevicesThe Cisco IOS software offers a in good ord er tool for gathering information about other directly connected devices through its Cisco Discovery Protocol (CDP).This chapters exercises center your attention on the benefits of using CDP as a network engineer. Other commands, including telnet and traceroute, are also part of your tool kit for learning about other network devices. So you spend some time on these as well. The eight Curriculum Labs focus your attention on the configuration tasks covered in the chapter. Two additional Comprehensive Labs help you review the commands and skills learned in the Curriculum Labs. Chapter 5, Managing Cisco IOS SoftwareThis chapter examines in detail how a router boots and loads the IOS.Knowing the default boot sequence as well as how to change the sequence is an important part of your network engineers skill set. Exercises focus on the boot sequence, the boot system commands, the configuration register, the IOS naming convention, and methods for uploading and downloading an IOS. The six Cu rriculum Labs focus your attention on the configuration tasks covered in the chapter. An additional Challenge Lab helps you review the commands and skills learned in the Curriculum Labs. xxxi Chapter 6, Routing and Routing ProtocolsThis chapter covers a crucial topic for any CCNA candidate routing.Exercises focus on reading routing table output from the show ip route command, using static routing, choosing a routing protocol, understanding can-do routing, and learning basic Routing Information Protocol (RIP) configuration. The Curriculum Lab focuses your attention on configuring static routes. Two additional labs, a Comprehensive Lab and Challenge Lab, help you review the commands and skills learned in the chapter. Chapter 7, Distance Vector Routing ProtocolsThis chapter covers how distance vector routing avoids loops.In addition, you extend your skills in configuring RIP and you learn some valuable troubleshooting tools. The seven Curriculum Labs focus your attention on the config uration tasks covered in the chapter. Two additional labs, a Comprehensive Lab and Challenge Lab, help you review the commands and skills learned in the chapter. Chapter 8, TCP/IP Suite Error and Control MessagesThis chapter takes a brief look at the Internet Control Message Protocol (ICMP). A basic understanding of the IP packet header and the most important ICMP messages are covered.There are no labs in this chapter. Chapter 9, Basic Router TroubleshootingThis chapter focuses exclusively on your troubleshooting skills. For a major(ip) part of the CCNA exam, you must be proficient at troubleshooting a unprejudiced internetwork.
