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.
