Welcome to the world of routing!

Routing is the technology that enables worldwide Internet communication. Many people involved with networking technologies or companies need to know how routing works. But learning about routing tends to involve a complex web of terms and acronyms-a language that can be difficult and unfamiliar.

No routing experience needed!

Routing First-Step explains the basics of Internet routing in language all of us can understand. This book takes you on a guided tour of routing, starting with systems you are familiar with: the postal system, the telephone system, and the interstate highway system. From there, you'll learn routing simply and easily. Whether you are looking to take your first step into a career in networking or are interested only in gaining knowledge of the technology, this book is for you!

5 of 5 people found the following review helpful Leaves a bit to be desired, June 28, 2005 By  Everyone's_a_critic (USA) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Routing First-Step (Paperback) This is one of three routing intro books in the Cisco Press line. It appears to be positioned at the very entry level, ostensibly because of its inclusion of a chapter explaining routing with a post office metaphor, and a chapter on decimal and binary numbers. Although the book is well organized, and covers the major routing protocols, it is surprising that, as an entry level book, there is no review of networking equipment, let alone an explanation of what a router is and how it functions. Many other basic routing concepts such as default routing and redistribution are not covered, but they may simple be beyond the scope of the book. However, explanations of various topics included in the book leave a bit to be desired. For example, the chapter on EIGRP mentions early on that EIGRP can support discontiguous networks. An example is provided with no immediate explanation. The student would be unable to apply the knowledge to a different scenario. Later in the...

Scheiderer (M. Hill, CA USA) - See all my reviews    This review is from: Routing First-Step (Paperback) Routing First-Step (Your first step into the world of routing) Reviewer Name: Steve Owen Scheiderer, Network Administrator Reviewer Certification: MCSE NT 4.0, CCNA ISBN: 1-58720-122-4 To earn my CCNA it took a year's worth of time in Cisco Academy modules, numerous labs, two 990+ page books, a test study guide, and the Cisco Simulator (which I also reviewed). Bill Parkhurst did an excellant job of summarizing basic concepts in under 400 pages. I would recommend Chapters 1 - 6 and 9 for those pursuing CCNA certification. What is difficult to understand, from the perspective of Cisco Academy material, is why topics like IS-IS and GP are included in this book. Even some of the OSPF discussion seems advanced (pp. 217-227). As a mere, humble CCNA, these sections were somewhat hard to follow and at times produced more questions than answers. On the other...

This book assumes that you have zero experience with what routing is, how it works, what's the addressing structure or anything else. It starts off with a discussion on how to set up a snail mail system using horses, kind of like the Post Office had to use in its early days. How would you address an envelope? There is a convention that says the return address goes in the top left hand corner. But it doesn't have to be there, if we all agreed, it could be where ever we liked. But it has to be somewhere. This is the level of detail of where the book begins. After that, it goes on to a highway system. You want to mail a letter from San Jose to Chicago, what kind of addressing do you need, where does the letter stop on its way. Finally, these conventions become standardized, and we give them names. The names just happen to be those of the computer protocols - surprise, surprise. By the end of the book he is...

Praise For Routing First-Step

"The author has done a wonderful job at taking a very complex subject, reducing it to its core components and presenting the material in an understandable format. When the reader completes this book, [he or she] will have a good understanding of the concepts of routing and routing protocols. I would recommend this book for those looking for an introduction to routing and IP addressing, and although I would not recommend this book as the sole resource in preparing for Cisco Certification, it definitely would assist in one's efforts."
– John Patty, Senior Network Engineer, CCNP, CCDP
