Cisco routers are used widely both on the Internet and in corporate intranets. At the same time, the Cisco Internet Operating System (IOS) has grown to be very large and complex, and Cisco documentation fills several volumes. Cisco IOS Access Lists focuses on a critical aspect of the Cisco IOS--access lists. Access lists are central to the task of securing routers and networks, and administrators cannot implement access control policies or traffic routing policies without them. Access lists are used to specify both the targets of network policies and the policies themselves. They specify packet filtering for firewalls all over the Internet. Cisco IOS Access Lists covers three critical areas:

• Intranets. The book serves as an introduction and a reference for network engineers implementing routing policies within intranet networking.

• Firewalls. The book is a supplement and companion reference to books such as Brent Chapman's Building Internet Firewalls. Packet filtering is an integral part of many firewall architectures, and Cisco IOS Access Lists describes common packet filtering tasks and provides a "bag of tricks" for firewall implementers.

• The Internet. This book is also a guide to the complicated world of route maps. Route maps are an arcane BGP construct necessary to make high level routing work on the Internet.

Cisco IOS Access Lists differs from other Cisco router titles in that it focuses on practical instructions for setting router access policies. The details of interfaces and routing protocol settings are not discussed.

Good idea, good attempt. Bad tech editors and reviewers. - 2004-03-24
Reviewer Rating:
I wouldn't recommend this book to novice network wizards. But for those who can see and identify errors, lets just consider this book as a tech quiz, a la "find and fix". It's been fun for me. Come on... It's impossible to know everything. Don't blame author. He has done a good work. He just didn't have a good support team. Yes, errors, yes, typos, and triple yes overall weight of all discrepancies almost ruin all other good impressions. But still, there are a lot of great and cool tips and tricks I have found.
Hope there will be another edition.

Good book to learn ACLs - 2002-08-29
Reviewer Rating:
This just the book one would like to read to go through the basics of Cisco ACLs. The author introduces the concepts with some very simple and easily understandable examples.

On the other hand, book is either a little outdated or author has intetionally not included many interesting ACL features. Features like turbo acls, dynamic acls, log input, extended communities are either not discussed or discussed very little in the book. The focus of the book is mostly control plane, the data plane is somewhat neglected.

Overall a decent book, at best a book for a beginner. For someone new to acls this book will help save a lot of time understanding acls, route-maps, prefix-lists, communities, as paths ....

Too many errors - 2003-02-28
Reviewer Rating:
Book has good content, but unfortunately has far too many errors for me to recommend. I can understand having errors but some are far too obvious to be excused. No doubt the author is very knowledgeable, but I hope in the future his work is more carefully edited.

Good book, would be great with better editing - 2003-03-05
Reviewer Rating:
This is a good book on Cisco IOS Access Lists, especially since there is only one other available in the market. Content is very good, as the author is knowledgable and has extensive experience. There are some errors, with better editing this book would have been worth 5 stars. Still worth reading since you can spot the errors once you have enough knowledge and use of access lists.

technical & essential - 2008-10-13
Reviewer Rating:
No matter how long you have been using routers & L3 switch devices, you need to either know access-lists inside out or have something close to hand to refer to.

If you only purchase a few books a year for technical reference this should be on your list.
