What Does This Book Cover?
This book covers everything you need to know to pass the ICND1 (100- 105) and ICND2 (200-105) exams, as well as the CCNA Composite (200-125) exam. But regardless of which path you choose, as I've said, taking plenty of time to study and practice with routers or a router simulator is the real key to success.
You will learn the following information in this book:
Chapter 1: Internetworking Chapters 1.14 map to the ICND1 exam. In Chapter 1, you will learn the basics of the Open Systems
Interconnection (OSI) model the way Cisco wants you to learn it. There are written labs and plenty of review questions to help you. Do not even think of skipping the fundamental written labs in this chapter!
Chapter 2: Ethernet Networking and Data Encapsulation This chapter will provide you with the Ethernet foundation you need in order to pass both the CCENT and CCNA exams. Data encapsulation is discussed in detail in this chapter as well. And as with the other chapters, this chapter includes written labs and review questions to help you.
Chapter 3: Introduction to TCP/IP This chapter provides you with the background necessary for success on the exam, as well as in the real world with a thorough presentation of TCP/IP. This in-depth chapter covers the very beginnings of the Internet Protocol stack and goes all the way to IP addressing and understanding the difference between a network address and a broadcast address before finally ending with network troubleshooting.
Chapter 4: Easy Subnetting You'll actually be able to subnet a network in your head after reading this chapter if you really want to! And you'll find plenty of help in this chapter as long as you don't skip the written labs and review questions at the end.
Chapter 5: VLSMs, Summarization, and Troubleshooting TCP/IP Here, you'll find out all about variable length subnet masks
(VLSMs) and how to design a network using VLSMs. This chapter will
finish with summarization techniques and configurations. As with Chapter 4, plenty of help is there for you if you don't skip the written lab and review questions.
Chapter 6: Cisco's Internetworking Operating System (IOS) This chapter introduces you to the Cisco Internetworking Operating System (IOS) and command-line interface (CLI). In this chapter you'll learn how to turn on a router and configure the basics of the IOS, including setting passwords, banners, and more. Hands-on labs will help you gain a firm grasp of the concepts taught in the chapter. Before you go through the hands-on labs, be sure to complete the written lab and review questions.
Chapter 7: Managing a Cisco Internetwork This chapter provides you with the management skills needed to run a Cisco IOS network. Backing up and restoring the IOS, as well as router configuration, are covered, as are the troubleshooting tools necessary to keep a network up and running. As always, before tackling the hands-on labs in this chapter, complete the written labs and review questions.
Chapter 8: Managing Cisco Devices This chapter describes the boot process of Cisco routers, the configuration register, and how to manage Cisco IOS files. The chapter finishes with a section on Cisco's new licensing strategy for IOS. Hands-on and written labs, along with review questions, will help you build a strong foundation for the objectives covered in this chapter.
Chapter 9: IP Routing This is a fun chapter because we will begin to build our network, add IP addresses, and route data between routers. You will also learn about static, default, and dynamic routing using RIP and RIPv2. Hands-on labs, a written lab, and the review questions will help you fully nail down IP routing.
Chapter 10: Layer 2 Switching This chapter sets you up with the solid background you need on layer 2 switching, how switches perform address learning and make forwarding and filtering decisions. In addition, switch port security with MAC addresses is covered in detail. As always, go through the hands-on labs, written lab, and reviewquestions to make sure you've really got layer 2 switching down!
Chapter 11: VLANs and Inter-VLAN Routing Here I cover
virtual VLANs and how to use them in your internetwork. This chapter covers the nitty-gritty of VLANs and the different concepts and protocols used with VLANs. I'll also guide you through
troubleshooting techniques in this all-important chapter. The hands- on labs, written lab, and review questions are there to reinforce the VLAN material.
Chapter 12: Security This chapter covers security and access lists, which are created on routers to filter the network. IP standard, extended, and named access lists are covered in detail. Written and hands-on labs, along with review questions, will help you study for the
security and access-list portion of the Cisco exams.
Chapter 13: Network Address Translation (NAT) New information, commands, troubleshooting, and detailed hands-on labs will help you nail the NAT CCENT objectives.
Chapter 14: Internet Protocol Version 6 (IPv6) This is a fun chapter chock-full of some great information. IPv6 is not the big, bad scary creature that most people think it is, and it's a really important objective on the latest exam, so study this chapter carefully—don't just skim it. And make sure you hit those hands-on labs hard!
Chapter 15: Enhanced Switched Technologies Chapter 15 is the first chapter of Part 2 of this book, which maps to the ICND2 exam. This chapter will start off with STP protocols and dive into the fundamentals, covering the modes, as well as the various flavors of STP. VLANs, trunks, and troubleshooting are covered as well. EtherChannel technologies, configuration, and verification are also covered. There are hands-on labs, a written lab, and plenty of review questions to help you. Do not even think of skipping the fundamental written and hands-on labs in this chapter!
Chapter 16: Network Device Management and Security Managing Cisco Devices This chapter describes the boot process of Cisco routers, the configuration register, and how to manage Cisco IOS files. The chapter finishes with a section on Cisco's new licensingstrategy for its IOS. Hands-on and written labs, along with review questions, will help you build a strong foundation for the objectives covered in this chapterhow to mitigate threats at the access layer using various security techniques. AAA with RADIUIS and TACACS+, SNMP and HSRP are also covered in this chapter. Don't skip the hands-on labs that are included, as well as a written lab and review questions at the end of the chapter.
Chapter 17: Enhanced IGRP EIGRP was not covered in the ICND1 (CCENT) chapters, so this is a full chapter on nothing but EIGRP and EIGRPv6. There are lots of examples, including configuration, verification, and troubleshooting labs, with both IP and with IPv6. Great hands-on labs are included, as well as a written lab and review
Chapter 18: Open Shortest Path First (OSPF) Chapter 9 dives into more complex dynamic routing by covering OSPF routing. The written lab, hands-on labs, and review questions will help you master this vital routing protocol.
Chapter 19: Multi-Area OSPF The ICND1 (CCENT) portion of this book had a large chapter on OSPF, so before reading this chapter, be sure you have the CCENT objectives down pat with a strong OSPF
foundation. This chapter will take off where that ICND1 chapter left off and add multi-area networks along with advanced configurations and then finish with OSPv3. Hands-on labs, a written lab, and challenging review questions await you at the end of the chapter.
Chapter 20: Troubleshooting IP, IPv6, and VLANs I want to say this is the most important chapter in the book, but that's hard to say. You can decide that yourself when you take the exam! Be sure to go through all the troubleshooting steps for IP, IPv6, and VLANs. The hands-on labs for this chapter will be included in the free bonus material and dynamic labs that I'll write and change as needed. Don't skip the written lab and review questions.
Chapter 21: Wide Area Networks This is the longest, and last, chapter in the book. It covers multiple protocols in depth, especially HDLC, PPP, and Frame Relay, along with a discussion on many other technologies. Good troubleshooting examples are provided in the PPP
and Frame Relay configuration sections, and these cannot be skipped! Hands-on labs meant to focus squarely on the objectives are included at the end of the chapter, as well as a written lab and challenging review questions.
Chapter 22: Evolution of Intelligent Networks I saved the hardest chapter for last. What makes this chapter challenging is that there is no configuration section to you really need to dive deep into the cloud, APIC-EM and QoS sections with an open and ready mind. I stuck as close to the objectives as possible in order to help you ace the exam. The written lab and review questions are spot on for the objectives.
Appendix A: Answers to Written Labs This appendix contains the answers to the book's written labs.
Appendix B: Answers to Chapter Review Questions This appendix provides the answers to the end-of-chapter review questions.
Appendix C: Disabling and Configuring Network Services Appendix C takes a look at the basic services you should disable on your routers to make your network less of a target for denial of service (DoS) attacks and break-in attempts.
