Chapter 1, "Getting Started in Internetworking," reviews the OSI reference model and gives an overview of the general types of internetworking devices that are at issue in this book: bridges, switches, and routers. The chapter concludes by describing a complete example internetwork for the fictional Zoom Integrated Products (ZIP) company.

Chapter 2, "The Basics of Device Configuration," describes the basic information that you need to know about a Cisco device, starting with its configuration out of the box. Topics covered include how to access the console port, basic terminal configuration, Cisco IOS software setup mode, context-sensitive help, privileged mode, and the IOS configuration command structure. This chapter also explains some of the physical characteristics of a Cisco device, such as accessing random access memory (RAM), saving configuration information to nonvolatile RAM (NVRAM), and transferring Cisco IOS software images to Flash memory.

Chapter 3, "The Basics of Device Interfaces," explains what you need to know about the various network interface types found on a Cisco device. The chapter introduces each of the following interface types and gives examples of how to configure the Cisco IOS software for each: Ethernet, Fast Ethernet, Gigabit Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), High-Level Data Link Control (HDLC), Point-to-Point Protocol (PPP), X.25, Frame Relay, Asynchronous Transfer Mode (ATM), Digital Subscriber Loop (DSL), and Integrated Services Digital Network (ISDN). The chapter includes explanations of how to use Cisco IOS software commands to examine interface status and health.

Chapter 4, "TCP/IP Basics," explains the basics of the Internet Protocol (IP): subnetting and routing. The chapter also shows you how to use the Cisco IOS software to configure IP addresses, IP routes, IP routing protocols (RIP, IGRP, OSPF, EIGRP, and BGP4), IP network security, and dialup IP. Other IP nuances in the Cisco IOS software, such as Domain Name Service (DNS) configuration, IP broadcast forwarding, DHCP services, and redundancy, are also explained.

Chapter 5, "AppleTalk Basics," covers a variety of topics, starting with an overview of the AppleTalk protocol suite. The chapter then covers the IOS configuration of AppleTalk cable-ranges, zones, routing protocols (RTMP and EIGRP), AppleTalk network security, and dialup AppleTalk.

Chapter 6, "IPX Basics," first overviews the components of the Novell Internetwork Packet Exchange (IPX) protocol: network numbers , the Service Advertising Protocol (SAP), and routing. Next is coverage of using the IOS to configure IPX addresses, multiple LAN encapsulation methods , routes, routing protocols (RIP, NLSP, and EIGRP), IPX network security, and dialup IPX.

Chapter 7, "Basic Administrative and Management Issues," explains other basic configuration items in the IOS that you need to understand. These items include access control, using Secure Shell (SSH) to access an IOS device, logging messages, network management protocols, and clock/calendar control. The chapter shows how to configure the Simple Network Management Protocol, the Terminal Access Controller Access Control System (TACACS and TACACS+), the Remote Authentication Dial-In User Service (RADIUS), and the Network Time Protocol (NTP).

Chapter 8, "Comprehensive IOS Configuration for the ZIP Network," gives complete IOS configurations for the entire example ZIP network. This chapter summarizes the configuration examples seen throughout the text.
