Authorized Self-Study Guide Designing for Cisco Internetwork Solutions (DESGN), Second Edition

Authorized Self-Study Guide Designing for Cisco Internetwork Solutions (DESGN), Second Edition


Modern networks are both extremely complex and critical to business success. As organizational processes continue to increase the requirements for bandwidth, reliability, and functionality from their networks, network designers are challenged to rapidly develop and evolve networks that use new protocols and technologies. Network designers are also challenged to stay current with the internetworking industry's constant and rapid changes. Designing robust, reliable, scalable networks is a necessary skill for network operators and designers in the modern organizational environment.

This book teaches you how to design enterprise networks. You will learn about network design in the context of the Cisco Service Oriented Network Architecture (SONA) architectural framework and Enterprise Architecture. Specific topics include campus and data center infrastructure, remote connectivity, IP addressing design, routing protocol selection, designing voice networks, wireless network design, and including security in your designs.

An ongoing case study and chapter-ending review questions illustrate and help solidify the concepts presented in this book.

This book provides you with the knowledge and skills you need to achieve associate-level competency in network design. It starts you down the path to attaining your CCDA certification, because it provides in-depth information to help you prepare for the DESGN exam.

DESGN is the first step in the design curriculum that supports the Cisco network design certification track. This book focuses on the technology and methods currently available.

Objectives of This Book

The goal of this book is to provide you with the knowledge you need to gather internetworking requirements, identify solutions, and design the network infrastructure and services to ensure basic functionality, using the principles of hierarchical network design to structure and modularize a converged enterprise network design. Design tasks might include understanding the design methodology; structuring and modularizing the network design using the Cisco Enterprise Architecture; designing the Enterprise Campus, Enterprise Data Center, Enterprise Edge, and remote modules as needed; designing an addressing plan and selecting suitable routing protocols; designing basic voice transport across the network; designing a basic wireless solution; and evaluating security solutions.

Who Should Read This Book

This book is intended for network and sales engineers who are involved in network design, planning, and implementation, and for those who plan to take the 640-863 DESGN exam toward the CCDA certification. This book provides in-depth study material for that exam. To fully benefit from this book, you should have the following prerequisite skills:

  • CCNA–level knowledge (or CCNA certification), which can best be achieved by completing the related CCNA courses and using CCNA books from Cisco Press. You can find more information on the CCNA certification at http://www.cisco.com/go/ccna/.

  • Knowledge of wireless networking, quality of service (QoS), and multilayer switching is highly recommended. The level equivalent to that covered in the Building Cisco Multilayer Switched Networks (BCMSN) course or the book Building Cisco Multilayer Switched Networks (BCMSN), Fourth Edition (Richard Froom, Balaji Sivasubramanian, Erum Frahim, Cisco Press, 2007) is appropriate.

  • NOTE - We assume that you understand the wireless networking material in the Cisco Press book just mentioned. In Chapter 9, we include some material from that book as an introduction to wireless technology. Refer to the Cisco Press BCMSN book for more detailed information.

  • Practical experience deploying and operating networks based on Cisco network devices and the Cisco IOS.

Summary of the Contents

The chapters and appendixes of this book are as follows:

  • Chapter 1, "Network Fundamentals Review," introduces some fundamental concepts and terminology that are the foundation for the material in the rest of the book.

  • Chapter 2, "Applying a Methodology to Network Design," introduces the Cisco vision of intelligent networks and the Service Oriented Network Architecture (SONA) architectural framework. The lifecycle of a network and a network design methodology based on the lifecycle are presented, and each phase of the network design process is explored in detail.

  • Chapter 3, "Structuring and Modularizing the Network," introduces a modular hierarchical approach to network design, the Cisco Enterprise Architecture. The chapter includes a detailed description of services within modular networks. Network management protocols and features are also discussed.

  • Chapter 4, "Designing Basic Campus and Data Center Networks," examines the design of the Enterprise Campus and Enterprise Data Center network infrastructure.

  • Chapter 5, "Designing Remote Connectivity," discusses WAN technologies and design considerations. This chapter describes the Enterprise WAN and metropolitan-area network (MAN) architectures and the Enterprise Branch and Teleworker architectures and discusses the selection of WAN hardware and software components.

  • Chapter 6, "Designing IP Addressing in the Network," discusses the design of an IP version 4 (IPv4) addressing scheme. The chapter also introduces IP version 6 (IPv6) and discusses IPv4-to-IPv6 migration strategies.

  • Chapter 7, "Selecting Routing Protocols for the Network," describes considerations for selecting the most appropriate network routing protocol. The chapter discusses why certain protocols are suitable for specific modules in the Enterprise Architecture. It concludes with a description of some advanced routing protocol deployment features, including redistribution, filtering, and summarization.

  • Chapter 8, "Voice Network Design Considerations," introduces voice design principles and provides guidelines for a successful integrated network deployment. It begins with an overview of traditional voice architectures and features and continues with a discussion of integrated voice architectures, including VoIP and IP telephony.

  • Chapter 9, "Wireless Network Design Considerations," introduces the Cisco Unified Wireless Network (UWN) architecture and discusses wireless design principles. The chapter introduces wireless technologies and explores considerations when designing Cisco UWNs in enterprise environments.

  • Chapter 10, "Evaluating Security Solutions for the Network," describes network security, including threats and risks, and network security policies. The Cisco Self-Defending Network strategy for designing network security is explored, and Cisco network security solutions for enterprise networks are discussed.

  • Appendix A, "Answers to Review Questions and Case Studies," contains answers to the review questions and case studies that appear at the end of the chapters.

  • Appendix B, "IPv4 Supplement," provides job aids and supplementary information intended for your use when working with IPv4 addresses. Topics include an IP addressing and subnetting job aid, a decimal-to-binary conversion chart, IPv4 addressing review, and IPv4 access lists.

  • Appendix C, "Open Systems Interconnection (OSI) Reference Model," is a brief overview of the OSI seven-layer model.

  • Appendix D, "Network Address Translation," contains information about Cisco's implementation of Network Address Translation (NAT) and port address translation (PAT).

  • "Acronyms and Abbreviations" spells out the abbreviations, acronyms, and initialisms used in this book.

Case Studies and Review Questions

Starting in Chapter 2, each chapter concludes with a case study on Acme County Medical Center (ACMC) Hospital, a fictitious small county hospital in the United States, to help you evaluate your understanding of the concepts presented. In each task of the case study, you act as a network design consultant and make creative proposals to accomplish the customer's business needs. The final goal of each case study is a paper solution. Also starting in Chapter 2, each chapter also includes review questions on the subjects covered in that chapter so that you can test your knowledge.

To find out how you did and what material you might need to study further, you can compare your answers to those provided in Appendix A. Note that for each case study task, Appendix A provides a solution based on the assumptions made. There is no claim that the provided solution is the best or only solution. Your solution might be more appropriate for the assumptions you made. The provided solution allows you to understand the author's reasoning and offers you a means of comparing and contrasting your solution.

I really have some difficulty with this book. I have a lot of network design experience and a CCNA, but I need to learn the "Cisco way" of network design. This book is 930 pages long, but I think with a little effort the information within it could have been condensed into under 100 pages. there's so much to read to get to the meat of the subject. And when I look back at the pages I earmared for re-reading later, there are many pages each with just a small amount of info I want to go over again before the exam.

In at least one case, each bullet point in a list was a paragraph long, and the summary at the end of the bullet list was simply a repeat of the last bullet point. It seems that there was a concious effort to "pad out" the book.

The book does not cover all the information needed to pass this intro-level course in design (it refers you out to texts for the next level course up: eg. Building Cisco Multilayer Switch Networks). To my mind, one should not have to purchase reference material for the advanced courses in order to be able to get through the introductory courses.

All in all an overly-hard read and, at times it seems, more focussed on advertising Cisco product and positioning Cisco as a locked-in solution than on helping one through the CCDA exam.

After 570 pages of text, I have little clue as to what kinds of questions will be on the exam to come (at least in terms of the design questions).

I've been studying this book now for several weeks, and have made a couple attempts at taking the 640-863 test. This book covers many topics to some depth and includes a lot of useful information around modern networking design, from a Cisco viewpoint.

It is, in my opinion, not in and of itself enough to pass the exam. There are many places which are confusing - some of which have direct consequences when it comes to taking the 640-863 exam. Many sections appear to be little more than bulleted lists yanked from product marketing papers.

The section explaining PPDIOO, for example, first lays out the PPDIOO methodology and then a few pages later lays out a similar or overlapping methodology having two parts with three numbered steps each. The author then references the similar but not exact mappings to PPDIOO. Why does the world need 2 different similar six step methodologies to memorize? Worse, this confusing mess specifically contradicts itself in a number of places, which may or may not be (ok, they will be) later included as questions on the test. As well, there are also a few topics which show up on the exam that simply don't appear to be well covered by this text.

Overall - I have accumulated a bunch of network design knowledge, some of which may well be useful for my job, but as far as being able to pass the exam, I find myself more confused, more frustrated and more broke. This book needs a good editor and/or a rewrite. If it is going to be an Authorized Self Study guide, it should illuminate, not confuse and confound. Perhaps it should be sold as a companion to the Official Self Study Guide?

This book is a required textbook for my Master's level course in Network Analysis for the CNSS 4011 training standard. The lack of page numbers and odd pagination in the Kindle version make it very difficult to use. In my experience, it's not worth the $7 savings and portability compared to the print version.

I like this book but remember it is meant for designers. A lot of it involves stuff that happens only in certain situations and in many times in real life might never happen, but you must design for the worst case senario.
