Pick up where certification exams leave off. With this practical, in-depth guide to the entire network infrastructure, you’ll learn how to deal with real Cisco networks, rather than the hypothetical situations presented on exams like the CCNA. Network Warrior takes you step by step through the world of routers, switches, firewalls, and other technologies based on the author's extensive field experience. You'll find new content for MPLS, IPv6, VoIP, and wireless in this completely revised second edition, along with examples of Cisco Nexus 5000 and 7000 switches throughout.

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
  • Security, firewall theory, and configuration, as well as ACL and authentication
  • Quality of Service (QoS), with an emphasis on low-latency queuing (LLQ)
  • IP address allocation, Network Time Protocol (NTP), and device failures

Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly.

That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right.



Thoroughly revised and expanded, Cisco IOS Cookbook, 2nd Edition, adds sections on MPLS, Security, IPv6, and IP Mobility, and presents solutions to the most common configuration problems, including:

Configuring interfaces of many types, from serial to ATM and Frame RelayConfiguring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP)Configuring authenticationConfiguring other services, including DHCP and NTPSetting up backup links, and using HSRP to configure backup routersManaging the router, including SNMP and other solutionsUsing access lists to control the traffic through the router

If you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced--if you've just been given responsibility for managing a network with Cisco routers--this book could be a job-saver.

Packed with the latest information on TCP/IP standards and protocols

TCP/IP is a hot topic, because it's the glue that holds the Internet and the Web together, and network administrators need to stay on top of the latest developments. TCP/IP For Dummies, 6th Edition, is both an introduction to the basics for beginners as well as the perfect go-to resource for TCP/IP veterans.

The book includes the latest on Web protocols and new hardware, plus very timely information on how TCP/IP secures connectivity for blogging, vlogging, photoblogging, and social networking. Step-by-step instructions show you how to install and set up TCP/IP on clients and servers; build security with encryption, authentication, digital certificates, and signatures; handle new voice and mobile technologies, and much more.

Transmission Control Protocol / Internet Protocol (TCP/IP) is the de facto standard transmission medium worldwide for computer-to-computer communications; intranets, private internets, and the Internet are all built on TCP/IP The book shows you how to install and configure TCP/IP and its applications on clients and servers; explains intranets, extranets, and virtual private networks (VPNs); provides step-by-step information on building and enforcing security; and covers all the newest protocols You'll learn how to use encryption, authentication, digital certificates, and signatures to set up a secure Internet credit card transaction

Find practical security tips, a Quick Start Security Guide, and still more in this practical guide.

Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS.

If you work with Cisco routers, it's likely that you deal with Cisco's IOS software--an extremely powerful and complex operating system, with an equally complex configuration language. With a cryptic command-line interface and thousands of commands--some of which mean different things in different situations--it doesn't have a reputation for being user-friendly.

Fortunately, there's help. This second edition of Cisco IOS in a Nutshell consolidates the most important commands and features of IOS into a single, well-organized volume that you'll find refreshingly user-friendly.

This handy, two-part reference covers IOS configuration for the TCP/IP protocol family. The first section includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security. A brief, example-filled tutorial shows you how to accomplish common tasks.

The second part is a classic O'Reilly quick reference to all the commands for working with TCP/IP and the lower-level protocols on which it relies. Brief descriptions and lists of options help you zero in on the commands you for the task at hand. Updated to cover Cisco IOS Software Major Release 12.3, this second edition includes lots of examples of the most common configuration steps for the routers themselves. It's a timely guide that any network administrator will come to rely on.

Written by networking veteran with 20 years of experience, Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well.

Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers:

The type of networks now in use, from LANs, WANs and MANs to CANs



The OSI Model and the layers involved in sending dataHubs, repeaters, switches, and trunks in practiceAuto negotiation and why it 's a common problem in network slowdownsRoute maps, routing protocols, and switching algorithms in Cisco routersThe resilient Ethernet -- how to make things truly redundantCisco 6500 multi-layer switches and the Catalyst 3750 switchTelecom nomenclature -- why it 's different from the data worldT1 and DS3Firewall theory, designing access lists, authentication in Cisco devicesServer load balancing technologyContent switch module in actionDesigning QOS and what QOS does not doIP design and subnetting made easy



The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.
