Product Description
A thorough guide to understanding IP behavior in a router-based network
- Learn IP behavior in a Cisco router-based network from an expert
- Examine proven, effective troubleshooting techniques to eliminate the need for additional technical support
- Master IP fundamentals that everyone supporting an IP network needs to know
- Study visual explanations of complex real-world scenarios
IP Routing Primer focuses on how IP routing behaves in a Cisco router environment and also shows how you can use Cisco routers as a learning tool. In addition to teaching the core fundamentals, this book enhances your ability to troubleshoot IP routing problems yourself, often eliminating the need to call for additional technical support. In instances where additional support is required, this book will help you work more efficiently with customer support engineers by enhancing your ability to describe problems correctly.
The information is presented in an approachable, workbook-type format with dozens of detailed illustrations and real life scenarios integrated throughout.
From the Author
Why I wrote this book and what I hope it can do for youI wrote this book to help people who want to learn how IP behaves in a router-based network but don't have a local expert to learn from. Many of the people who have become experts in IP Internetworking since the beginning of the Internet had the advantage of learning from their peers and from the broader Internet community. They also benefited from the fact that they developed their understanding and knowledge during the evolution of the technologies that make the Internet what it is today.
Anybody attempting to enter the world of IP internetworking support today has a daunting task ahead of them The technologies already in place are extremely complex and the changes just keep on coming. And the one thing that everybody needs to understand - how IP actually behaves in a router-based network - is often miss understood or not understood at all. For example; ask any three people what "IP Routing Convergence" really means and you are very likely to get three very different answers. This book attempts to get beyond theoretical discussions of IP convergence by actually showing what happens when a network loses a transmission link and must converge on a new topology. It also avoids expressing opinions on what "should" happen during IP convergence by showing in detail what actually happens. IP convergence is only one of the topics that are presented in this real world manner. How routers make decisions on where to forward IP packets and many other concepts are included as well.
This book was not written with the intent of teaching Cisco router configuration techniques or how to design networks with Cisco routers. Nor is it intended to be an in depth guide to the TCP/IP protocol suite or to specific routing protocols like IGRP, EIGRP, BGP or OSPF.
