Organization

This book has 14 chapters and 1 appendix. As just described, they have a consistent structure, including an overview, Scenarios with detailed explanations, examples, Practical Exercises, and Review Questions. The chapters are as follows:

Chapter 1, "Introduction to Remote Access," introduces the various types of remote-access technologies, networks, and their users.
Chapter 2, "Building a CCNP Remote-Access Lab," covers creating LANs and WANs, as well as asynchronous, ISDN, PPP, DDR, dial backup, AAA, and security labs.
Chapter 3, "Modem Connections and Operation Overview," covers modem operation, communication, and configuration. Basic and automatic modem configurations are covered in detail.
Chapter 4, "Using Cable Modems to Access a Central Site," covers cable modems and their configuration. It contains an overview of cable modem technology, including transmission systems, protocols, and technology issues. The configuration of headend and CPE equipment is also covered.
Chapter 5, "Configuring Point-to-Point Protocol and Controlling Network Access," covers the configuration of PPP. Basic PPP features and operation are described. The configuration covers PPP callback, authentication, and compression.
Chapter 6, "Using ISDN and DDR Technologies to Enhance Remote Connectivity," covers the basic use of ISDN. Included is an overview of ISDN, including the different kinds of network equipment, ISDN bandwidth, and channels. The process of call setup and teardown is examined. The configuration of ISDN PRI and BRI is examined, including some optional configurations such as Multilink PPP.
Chapter 7, "Optimizing the Use of DDR with Interface Dialer Profiles and Rotary Groups," covers the more-advanced topic of ISDN in a DDR scenario. The topic of DDR is covered, and DDR configuration is demonstrated. This chapter also covers the optimization of DDR interfaces using features such as dialer groups and dialer profiles.
Chapter 8, "Using DSL to Access a Central Site," covers the basic use of DSL. It includes an overview of the various flavors of DSL. The different Cisco products in the DSL space are covered. The configuration section covers DSLAM configuration at Layer 2 and PPPoE and PPPoA configuration at Layer 3.
Chapter 9, "Frame Relay Connectivity and Traffic Flow Control," covers the important topic of Frame Relay. It offers an overview of Frame Relay, including Frame Relay basics and signaling. The configuration of Frame Relay subinterfaces and traffic shaping is demonstrated. Issues and solutions relating to these topics are also covered.
Chapter 10, "Enabling a Backup to the Permanent Connection," covers the configuration and use of dial backup. The basic theory and operation are discussed, including the various options such as physical versus dialer interfaces and load sharing versus load balancing.
Chapter 11, "Managing Network Performance with Queuing and Compression," covers queuing and compression and their impact on network performance. Queuing basics are covered, including the various flavors and their operation. The configuration covers the use of Weighted Fair Queuing, priority queuing, and custom queuing. Data compression is discussed and its configuration demonstrated.
Chapter 12, "Scaling IP Addressing with Network Address Translation," covers the use and configuration of NAT. The concept of NAT and its components are discussed. The configuration section covers the topics of static NAT, dynamic NAT, and Port Address Translation.
Chapter 13, "Using AAA to Scale Access Control in an Expanding Network," covers the concept of AAA and Cisco's Cisco Secure product. An overview of AAA and its individual components is given. The Cisco Secure product is examined from both the client and server perspective. Then AAA is configured on both client and server using Cisco Secure.
Chapter 14, "Securing Remote-Access Networks," covers the configuration and use of VPNs in a remote-access scenario. The overview covers the different components of IPSec, including ESP, AH, and IKE. The various Cisco products in this space are also described. The configuration section covers the different VPN configurations, including router-to-router, VPN client-to-router, and VPN client-to-PIX.
Appendix A, "Answers to Review Questions," provides answers to the chapter-ending review questions.
