⭐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.

⭐Overall great read even if it is a bit dated to today protocols and standards. Started reading this right after passing the CCNA and really provided a huge bridge between knowledge and actually implementing these skills into the real world and troubleshooting you are likely to encounter. Definitely recommend this to anyone who wants to push their Networking knowledge.

⭐I actually bought this book 8 years ago. I have read it through every few years. In the last few years, I have also boughten it for a few other people, and everyone says this is THE best networking book they have read, after studying the CCNA.Tips from this book you would have to work for a company a few years to get this same kind of advice.

⭐First off, thank you reviewers for your thoughts on this book, it’s what lead me into buying this book. This book makes studying for my CCNA that much more enjoyable. This book helps to embolden my confidence towards the world of networking and specifically with Cisco. While watching study videos, reading my main ccna study book, and this, I seem to be retaining everything with confidence. I genuinely want to grasp a deep understanding with how all this works and the author helps to put you in an interactive mindset. He knows the questions your thinking and elaborates on issues expressed in real life network scenarios.Whether I’m labbing with his examples, or simply leaning back in my chair for a good read, this is the book I look forward to reading. I never would of thought picking it up would be this enjoyable, that helps me get through the studying grind in a totally different light.

⭐I read this to prepare for setting up my first network; which happened to be an 8 story building with two IDFs per floor and enough fiber for an entire nursing home. I went with D-Link managed switches for a Cisco free network. I’m a programmer but had little practical experience in networking outside of SOHO setups and virtualization.The majority of this book (page-wise) is Cisco specific configuration examples. I’d have found these examples to be invaluable had I been using Cisco equipment, however, if you’re not they’re a nuisance. I understand the prevalence of Cisco gear and I don’t ding the book in that regard but some of the content didn’t prepare you for the world outside of Cisco.I felt better prepared but the section on VLANs is somewhat lacking. VLAN Trunking outside of the Cisco world is a different beastUsing D-Link?On D-Link switches, traffic is described as it enters the switch, not as it exits the switch. So, “untagged traffic” gets tagged in the switch and “tagged traffic” is presumed to be tagged going into the switch. Four IT people mistook the GUI to mean something else, although if you read it the way I just stated it, it makes perfect sense. VLAN trunking doesn’t do what it does with Cisco, you’re better off allowing tagged traffic from all VLANs than doing a trunk. You can have untagged traffic on VLAN 1 and another VLAN simultaneously, so if you’re using the GUI be careful you don’t have two untagged VLANs (unless that’s what you want…)Overall, a nice book to have on your shelf, it won’t get you ready to set up a non-Cisco network.

⭐Bought the first edition quite a few years back and really found it informative with just enough info on the topics at hand.That book was very well thought out and didn’t drone on just like this new edition.This a great book just like the first and i recommend it any one curious about Networking whether a CCNA or not.Lots of good explanations we all can understand,digest and get to grips with.10/10

⭐Brilliant book, definitely useful in the real world not just exam scenario!!

⭐Das Buch ist Klasse. Ich bin zur Netzwerktechnik gekommen wie die Jungfrau zum Kind. Habe die CCNA Kurse besucht und danach ging es los. Ich habe das Buch gekauft um vielleicht den einen oder anderen Tipp zu bekommen. Hier passt das Buch. Es gibt einen ergänzenden Überblick der Netzwerktechnik. Wobei der Autor aus seinen praktischen Erfahrungen als Netzwerker berichtet und hier manchmal recht witzig rüber kommt. Das Thema Switching in Bezug auf Multicasts ist mir etwas zu kurz gekommen, was aber an meinem speziellen Tätigkeitsfeld liegt. Ich werde mir noch mehr Literatur aus der Reihe anschaffen.Genau wie der Autor es beschreibt, es fängt da an wo der CCNA R&S aufhörte und ist ein idealles Buch um schnell sein Wissen aufzufrischen.Für Anfänger oder Amateure ist dieses Buch in keinster Weise geeignet.Sehr erfreulich sind die Chapter bezüglich “Entscheider” und sonstige “Wannabes”.TOPIch hatte damals aus reiner Lernsucht nach einem Weg gesucht, wie ich nach dem Bestehen des CCNAs weiter machen kann. Dieses Buch ist für mich genau das richtige. Inhaltlich voll von Praxiserfahrungen, die mir aktuell beim Troubleshooting viel Verständnis und neues Wissen vermitteln. Ich kann es nur empfehlen, auch wenn ich wenig zu den Konfigurationsanleitungen sagen kann, da ich die Teile im Buch meistens überspringe. Normalerweise schlage ich sowas einfach im offiziellen und aktuellen CLI Reference Guide nach, was ich allen anderen Lesern auch nur wärmstens empfehlen kann.
