Topics include:

  • An in-depth view of routers and routing
  • Switching, using Cisco Catalyst and Nexus switches as examples
  • SOHO VoIP and SOHO wireless access point design and configuration
  • Introduction to IPv6 with configuration examples
  • Telecom technologies in the data-networking world, including T1, DS3, frame relay, and MPLS

      Well written book. Clearly written and provides great examples. Only reason for not giving it 5 stars is I haven't finished reading it.

        This book is hands down one of the best books on Cisco networking I have ever read. I'm a current CCNA studying for my CCNP and it blew my mind. It covers such a vast amount of information, but it's written in such a way that it's easy to comprehend and is applicable to real networking. It's as if someone blended every best of breed book on Cisco networking and laid it all out from the perspective of the enginner that is doing the actual work. Kudos to O'Reilly Publications--this is a great and useful book! I look forward to more in future!

              This book is a must for not only for seasoned engineers in the field, but for those aspiring to enter the networking field and those already in the field with limited experience. Although I found the technical content extremely helpful and enlighting, I found the GAD maxiums invaluable, especially when dealing with production environments! I wish I would have found this book before I took the CCNA exam. The explainations pretaining to CCNA level topics are explained very well in a high level overview that actually aids dealing with the more technical aspects of the given topic. If you are preparing for the ICND1, ICND2, or CCNA exam you will find this book a valuable addition to your study material. All in all, there is something here in the text for everyone regardless of your level of expertise. Kudos Gary for well prepared and through book. Looking forward to the 3rd edition!

                Hey guys, im taking the ccna, and i will drop a advise.

                Surely, if you want ccna you have to buy the official guides, but if you want to understand the things better, buy this book. All ccna students most have the book.

                Second edition does not disappoint!

                Comments about O'Reilly Media Network Warrior, 2nd Edition:

                If you walk into any networking geeks secret lair and scan your eyes along the endless horizon of nerdomenclature, you'll undoubtedly find Gary Donahue's original Networking Warrior somewhere pressed up against a vast collection of Cisco Press, Sybex, O'Reilly and occasional Max Brooks literature. From the beginning Gary Donahue's masterpiece has been widely accepted as thee' post CCNA book for every Cisco guy since 2007. As the unofficial go to manual for everything untaught on the CCNA a Cisco network engineer needs to know, Gary has taken his place among the elite masters Cisco authors such as Jeff Doyle, Wendell Odom, Jeremy Cioara and David Hucaby just to name a few.

                Networking Warrior Second Edition has updated it's core example technologies to reflect the ever evolving industry we as network engineers work with on a daily bassis. Giving us operational examples on Cisco new cutting edge equipment including the Cisco ASA Firewalls 8.0+ IOS, 3750 & 6500 switches and even the super-cool new Nexis product line emerging from the dark shadows intending to over the world one packet at a time. Gary takes his time at the end of each applicable chapter to explain the differences of implementing each technology though the IOS, CatIOS and new Nexus NX-OS giving clear examples that are easy to follow doubling this book as an excellent field manual alongside the extremely popular Portable Command Guides published by Cisco Press.

                What make book unique from most publishing's is Gary's sparkling humor scatted throughout his writings. One moment he will be explaining the technical aspect of the subject, the next he'll be making a metaphor funny enough to make your Spouse look over your shoulder and ask "whats so funny?", and after the fourth or fifth time may or may not be a good thing. Even though this book flows very well, it is not without it's fresh off the print edition errors. There are areas in the text where examples have not been updated to reflect the new books updated example equipment, other areas have diagram abnormalities, but we're not here to judge Gary's wife's editorial skills. I'm sure it's hared enough just to put up with him (joking of course).

                Garry mentions and gives a great amount credit to his wife as being his front line editor though the many months involved in writing this book.

                Networking Warrior spans an impressive 41 chapters covering a slue of topics. Just holding this book in your hands and thumbing though the chapter indexes gives you an idea of just how much Gary covers. I'd like to say this book is an excellent cover to cover read, and in some major blocks it is, but there are some section that no matter how supper-geek status you give yourself you'll just find yourself over inundated with information or lack of understanding, especially if you're fresh off the CCNA boat. The clear cut and skinny on this book is: If you're a CCNA looking for the next step, or a networking nut wanting to freshen up your knowledge of Cisco solutions you're in for a treat. Because Gary Donahue has everything but gift wrapped you the next book to fill that empty slot on your bookshelf. If is, if it ever gets off your desk.

                  Comments about O'Reilly Media Network Warrior, 2nd Edition:

                  Network Warrior, Second Edition is an update of the original (2007). The first volume was well worth reading, and this updated version is definitely on the "must read" list for anyone working with Cisco gear. Be aware that the book is Cisco-specific with regard to commands and vocabulary.

                  In the introduction, the author indicates that this book should be valuable to anyone with an entry-level Cisco-based skills (CCNA or better), but in my opinion it could also be useful to IT personnel who interact with network gear and are willing to do some additional background reading. For example, the book's lucid explanation of why autonegotiation causes problems could be of immense value to server team/sysadmin types (although obviously the router/switch config command listings are of less value to that audience).

                  One caveat to this book is that it should probably not be read by those attempting the CCNA or CCENT until *after* successfully taking the exams, unless you are certain you can sort out the Cisco "textbook" material from the "real world" discussions in Network Warrior.

                  Overall, this is a great book, well written, clearly illustrated and with examples that are hauntingly familiar to anyone who has supported Cisco networks of significant size.
