Jim Boney has worked for the last eight years as a consultant specializing in a wide variety of subjects: network design, network management, Unix administration, and programming in various languages (Perl, Java, Tcl/Tk, and C/C++). For the last three years, he has been working on the vLab project, which allows complete access to Cisco routers over the Internet.
Cisco IOS in a Nutshellby James Boney
Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread
Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS.
If you work with Cisco routers, it's likely that you deal with Cisco's IOS softwarean extremely powerful and complex operating system, with an equally complex configuration language. With a cryptic command-line interface and thousands of commandssome of which mean different things in different situationsit doesn't have a reputation for being user-friendly.
Fortunately, there's help. This second edition of Cisco IOS in a Nutshell consolidates the most important commands and features of IOS into a single, well-organized volume that you'll find refreshingly user-friendly.
This handy, two-part reference covers IOS configuration for the TCP/IP protocol family. The first section includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security. A brief, example-filled tutorial shows you how to accomplish common tasks.
The second part is a classic O'Reilly quick reference to all the commands for working with TCP/IP and the lower-level protocols on which it relies. Brief descriptions and lists of options help you zero in on the commands you for the task at hand. Updated to cover Cisco IOS Software Major Release 12.3, this second edition includes lots of examples of the most common configuration steps for the routers themselves. It's a timely guide that any network administrator will come to rely on.

Are you a network administrator who is using a Cisco router in an IP environment? If you are, this book is for you. Author James Boney, has written an outstanding 2nd edition of a book that is for everybody who has to deal with Cisco's routers. Boney, begins by covering the Cisco user interface. Then, he discusses several methods for uploading a new IOS image. The author continues by covering most of the configuration items that make routers more manageable and easier to tame. In addition, he shows you how to use line commands. The author also shows you how to use interface commands. Then, the author covers some networking technologies that you are likely to encounter, such as frame relay, ATM, cable, DSL, and VoIP. Next, he shows you how to use access lists. Next, the author discusses a number of topics that are common to all of the protocols. Then, he discusses interior routing protocols, including Routing Information Protocol (RIP) the Interior Gateway Routing Protocol (IGRP), and the newer Enhanced IGRP (EIGRP) Open Shortest Path First (OSPF), and Intermediate System-to-Intermediate System (IS-IS). The author continues by discussing the Border Gateway Protocol. In addition, he covers Cisco's new advanced tools for QoS management as well: Modular QoS CLI (MQC), Class-Based Weighted Fair Queing (CBWFQ), and Network-Based Application Recognition (NBAR). In addition, he covers Cisco's IOS support for dial-on-demand categories: Legacy DDR and Dialer profiles. The author also covers a number of IP configuration topics that won't find their way into simple configurations. Then, the author describes Cisco switches, with an emphasis on IOS-enabled switches. Next, the author describes the first simple steps you can take toward router security. Finally, he discusses techniques for troubleshooting and monitoring your router. This excellent book is primarily a quick reference to the commands that are most frequently needed to configure Cisco routers for standard IP routing tasks. Above all, this book represents practical experience with IP routing on Cisco routers and covers commands that you're likely to need.
and not much more. But then again, they did not promise much else... For more in depth coverage of routing protocols check out 'Cisco IOS for IP Routing' by Andrew Colton. These two together should take you a long way to a good understanding of Cisco routing.
