Introduction

Introduction

Since the introduction of the personal computer in the early 1970s, businesses have found more uses and applications for technology in the workplace. With the introduction of local-area networks, file sharing, and print sharing in the 1980s, it became obvious that distributed computing was no longer a passing fad. By the 1990s, computers became less expensive, and innovations such as the Internet allowed everyone to connect to computer services worldwide. Computing services have become large and distributed. The days of punch cards and green-bar paper are behind us, and a new generation of computing experts is being asked to keep this distributed technology operational. These experts are destined to have a new set of issues and problems to deal with, the most complex of them being connectivity and compatibility among differing systems and devices.

The primary challenge with data networking today is to link multiple devices' protocols and sites with maximum effectiveness and ease of use for end users. Of course, this must all be accomplished in a cost-effective way. Cisco offers a variety of products to give network managers and analysts the ability to face and solve the challenges of internetworking.

In an effort to ensure that these networking professionals have the knowledge to perform these arduous tasks, Cisco has developed a series of courses and certifications that act as benchmarks for internetworking professionals. These courses help internetworking professionals learn the fundamentals of internetworking technologies along with skills in configuring and installing Cisco products. The certification exams are designed to be a litmus test for the skills required to perform at various levels of internetworking. The Cisco certifications range from the associate level, Cisco Certified Network Associate (CCNA), through the professional level, Cisco Certified Network Professional (CCNP), to the expert level, Cisco Certified Internetwork Expert (CCIE).

The Interconnecting Cisco Network Devices, Part 2 (ICND2) course is one of two recommended training classes for CCNA preparation. As a self-study complement to the course, this book helps to ground individuals in the fundamentals of switches and routed internetworks. It presents the concepts, commands, and practices required to configure Cisco switches and routers to operate in corporate internetworks. You will be introduced to all the basic concepts and configuration procedures required to build a multiswitch, multirouter, and multigroup internetwork that uses LAN and WAN interfaces for the most commonly used routing and routed protocols. ICND provides the installation and configuration information that network administrators require to install and configure Cisco products.

Interconnecting Cisco Network Devices, Part 2 (ICND2), is the second part of a two-part, introductory-level series and is recommended for individuals who have one to three years of internetworking experience, are familiar with basic internetworking concepts, and have basic experience with the TCP/IP protocol. While the self-study book is designed for those who are pursuing the CCNA certification, it is also useful for network administrators responsible for implementing and managing small- and medium-sized business networks. Network support staff who perform a help-desk role in a medium- or enterprise-sized company will find this a valuable resource. Finally, Cisco customers or channel resellers and network technicians entering the internetworking industry who are new to Cisco products can benefit from the contents of this book.

Goals

The goal of this book is twofold. First, it is intended as a self-study book for the ICND2 test 640-816 and the CCNA test 640-802, which are part of the requirements for the CCNA certification. Like the certification itself, the book should help readers become literate in the use of switches, routers, and the associated protocols and technologies. The second goal is that someone who completes the book and the CCNA certification should be able to use these skills to select, connect, and configure Cisco devices in an internetworking environment. In particular, the book covers the basic steps and processes involved with moving data through the network using routing and Layer 2 switching.

Readers interested in more information about the CCNA certification should consult the Cisco website at http://www.cisco.com/en/US/learning/le3/le2/le0/le9/learning_certification_type_home.html. To schedule a Cisco certification test, contact Pearson Vue on the web at http://www.PearsonVue.com/cisco or Prometric on the web at http://www.2test.com.

Chapter Organization

This book is divided into eight chapters and an appendix and is designed to be read in order because many chapters build on content from previous chapters.

• Chapter 1, "Review of Cisco IOS for Routers and Switches," provides a review of the Cisco IOS. This is an assumed knowledge for readers, but this chapter provides a brief review of command structure that is used throughout the other chapters of the book.

• Chapter 2, "Medium-Sized Switched Network Construction," explores the operation and configuration of local-area networks, including the challenges associated with these networks, and describes how network devices are used to eliminate these problems focusing on Layer 2 switching.

• Chapter 3, "Medium-Sized Routed Network Construction," describes routing operations. This chapter discusses the differences between link-state and distance vector routing protocols and provides the foundation for Chapters 4 and 5.

• Chapter 4, "Single-Area OSPF Implementation," looks at how to configure OSPF to act as a routing protocol within a network. This chapter describes the operation of the protocol and provides configuration examples for a single area. The chapter also includes troubleshooting steps.

• Chapter 5, "Implementing EIGRP," discusses the EIGRP routing protocol. It describes the operation of the protocol and the configuration requirements. It also includes troubleshooting steps.

• Chapter 6, "Managing Traffic with Access Control Lists," discusses how access control lists are used in Cisco IOS to identify and filter traffic. The chapter discusses the configuration of the lists and provides some practical applications of these lists.

• Chapter 7, "Managing Address Spaces with NAT and IPv6," discusses the limitations of IPv4 address space, specifically that these addresses are running out. The chapter discusses how Network Address Translation (NAT) and Port Address Translation (PAT) are helping conserve addresses and how IPv6 will alleviate this problem. The chapter also discusses the configuration of NAT, PAT, and IPv6.

• Chapter 8, "Extending the Network into the WAN," describes how different sites can be connected across a wide-area network or using the Internet. It discusses VPN and SSL VPN (WebVPN) solutions as well as traditional leased line and Frame Relay connections. The chapter also provides a troubleshooting section.

• The appendix, "Answers to Chapter Review Questions," provides answers to the review questions at the end of each chapter.

Features

This book features actual router and switch output to aid in the discussion of the configuration of these devices. Many notes, tips, and cautions are also spread throughout the text. In addition, you can find many references to standards, documents, books, and websites to help you understand networking concepts. At the end of each chapter, your comprehension and knowledge are tested by review questions prepared by a certified Cisco instructor.

Note - The operating systems used in this book are Cisco IOS Software Release 12.4 for the routers, and Cisco Catalyst 2960 is based on Cisco IOS Software Release 12.2.
