Network Warrior

By Gary A. Donahue

Pick up the place certification assessments go away off. With this sensible, in-depth consultant to the total community infrastructure, you’ll how to take care of genuine Cisco networks, instead of the hypothetical occasions provided on tests just like the CCNA. Network Warrior takes you step-by-step in the course of the global of routers, switches, firewalls, and different applied sciences in accordance with the author's huge box event. you will find new content material for MPLS, IPv6, VoIP, and instant during this thoroughly revised moment variation, besides examples of Cisco Nexus 5000 and 7000 switches throughout.

Topics include:

  • An in-depth view of routers and routing
  • Switching, utilizing Cisco Catalyst and Nexus switches as examples
  • SOHO VoIP and SOHO instant entry aspect layout and configuration
  • Introduction to IPv6 with configuration examples
  • Telecom applied sciences within the data-networking global, together with T1, DS3, body relay, and MPLS
  • Security, firewall conception, and configuration, in addition to ACL and authentication
  • Quality of carrier (QoS), with an emphasis on low-latency queuing (LLQ)
  • IP tackle allocation, community Time Protocol (NTP), and machine failures

731 xvi | desk of Contents Preface The examples utilized in this ebook are taken from my very own studies, in addition to from the studies of these with or for whom i've got had the excitement of operating. after all, for seen felony and honorable purposes, the precise info and any info that would display the identities of the opposite events concerned were replaced. Cisco apparatus is used for the examples inside this ebook and, with only a few exceptions, the examples are TCP/IP-based. you could argue booklet of this sort may still comprise examples utilizing diverse protocols and gear from a number of proprietors, and, to some extent, that argument is legitimate. despite the fact that, a e-book that goals to hide the breadth of applied sciences contained herein, whereas additionally trying to exhibit examples of those applied sciences from the viewpoint of other owners, will be particularly an impractical measurement. if truth be told that Cisco platforms (much to the chagrin of its rivals, I’m convinced) is the optimal participant within the networking area. Likewise, TCP/IP is the protocol of the web, and the protocol utilized by so much networked units. Is it the simplest protocol for the task? might be no longer, however it is the protocol in use at the present time, so it’s what I’ve utilized in all my examples. now not in the past, the Cisco CCIE examination nonetheless integrated Token Ring resource direction Bridging, AppleTalk, and IPX. these days are long past, even if, indicating that even Cisco is familiar with that TCP/IP is the place everyone seems to be heading. i've got incorporated a bankruptcy on IPv6 during this variation, because it appears like we’re heading that approach finally. WAN expertise can contain every little thing from dial-up modems (which, fortunately, have gotten really infrequent) to T1, DS3, SONET, MPLS, and so forth. we'll examine a lot of those subject matters, yet we won't delve too deeply into them, for they're the topic of whole books unto themselves—some of which can already take a seat subsequent to this one in your O’Reilly bookshelf. back, all of the examples utilized in this publication are drawn from actual stories, such a lot of which I confronted myself in the course of my occupation as a networking engineer, advisor, supervisor, and director. i've got run my very own corporation and feature had the excitement of operating with the very best humans within the undefined. The options awarded in those chapters are those my groups and that i came across or discovered approximately within the technique of resolving the problems we encountered. xvii I confronted a really difficult selection whilst writing the second one variation of this publication. may still I preserve the CatOS instructions or discard them in want of more recent Nexus NX-OS examples? This choice was once difficult not just simply because my inclusion of CatOS ended in a few compliment from my readers, but additionally simply because as of this writing in early 2011, I’m nonetheless seeing CatOS switches operating in huge firm and ecommerce networks. As such, i made a decision to maintain the CatOS examples and easily upload NX-OS instructions. i've got extra many subject matters during this ebook based on suggestions from readers. New themes comprise Cisco Nexus, instant, MPLS, IPv6, and Voice over IP (VoIP). a few of these issues are lined intensive, and others, corresponding to MPLS, are purposely mild for purposes defined within the chapters.
