To Our Valued Readers:
The Cisco Certified Network Professional program well deserves its position as the leading high-level
certification in the internetworking arena. Sybex is proud to have helped hundreds of thousands of
CCNP candidates prepare for their exams over the years, and we are excited about the opportunity
to continue to provide individuals with the knowledge and skills they’ll need to succeed in the highly
competitive IT industry.
With the recent revision of the four exams required for the CCNP
Routing, Switching, Remote
Access, and Support
Cisco raised the bar considerably, adding simulation questions to two of the
and refreshing the question pools of all exams to better reflect current technologies. Sybex welcomes
these changes as we strongly advocate a comprehensive and practical instructional approach to certi-
fication exam preparation. It has always been Sybex’s mission to teach exam candidates how new
technologies work in the real world, not to simply feed them answers to test questions. Sybex was
founded on the premise of providing technical skills to IT professionals, and we have continued to
build on that foundation. Over the years, we have made significant improvements to our study guides
based on feedback from readers, suggestions from instructors, and comments from industry leaders.
Cisco’s new CCNP exams are indeed challenging. The authors have worked hard to ensure that this
Study Guide is comprehensive, in-depth, and pedagogically sound. We’re confident that this book,
along with the collection of cutting-edge software study tools included on the CD, will meet and
exceed the demanding standards of the certification marketplace and help you, the CCNP exam
candidate, succeed in your endeavors.
Good luck in pursuit of your CCNP certification!

The authors would like to thank all the folks associated with Sybex who
helped get this book on the shelves. Sharon Wilkey was a superb editor. This
book would be a stack of typewritten pages without the layout finesse of
Rozi Harris, Stacey Loomis, and the compositors at Interactive Composition
Corporation. Tony Jonick and Jeff Wilson magically transformed sketches
into works of art. Thanks to technical editors Patrick Bass and Arthur Pfund
for being our watchdogs. Finally, our other watchdogs are the proof-
readers: thanks to Laurie O’Connell, Nancy Riddiough, Dave Nash, and
Sarah Tannehill.

Introduction
W
elcome to the exciting world of Cisco certification! You have
picked up this book because you want something better; namely, a better job
with more satisfaction. Rest assured that you have made a good decision.
Cisco certification can help you get your first networking job, or more
money and a promotion if you are already in the field.
Cisco certification can also improve your understanding of the internet-
working of more than just Cisco products: You will develop a complete
understanding of networking and how different network topologies work
together to form a network. This is beneficial to every networking job and is
the reason Cisco certification is in such high demand, even at companies with
few Cisco devices.
Cisco is the king of routing and switching, the Microsoft of the internet-
working world. The Cisco certifications reach beyond the popular certifica-
tions, such as the MCSE and CNE, to provide you with an indispensable
factor in understanding today’s network—insight into the Cisco world of
internetworking. By deciding that you want to become Cisco certified, you
are saying that you want to be the best—the best at routing and the best at
switching. This book will lead you in that direction.
How to Use This Book
If you want a solid foundation for the serious effort of preparing for the
Cisco Certified Network Professional (CCNP) Switching exam, then look no
further. We have spent hundreds of hours putting together this book with the
sole intention of helping you to pass the CCNP Switching exam.
This book is loaded with lots of valuable information, and you will get the
most out of your studying time if you understand how we put this book
together.
To best benefit from this book, we recommend the following study method:
1.
Take the assessment test immediately following this introduction.
(The answers are at the end of the test.) It’s OK if you don’t know any
of the answers; that is why you bought this book! Carefully read over
the explanations for any question you get wrong and note which chap-
ters the material comes from. This information should help you plan
your study strategy.

Introduction
2.
Study each chapter thoroughly, making sure that you fully understand
the information and the test objectives listed at the beginning of each
chapter. Pay extra-close attention to any chapter where you missed
questions in the assessment test.
3.
If you do not have Cisco equipment available, be sure to study the
examples carefully. Also, check
www.routersim.com
for router simu-
lator software that provides drag-and-drop networking configurations.
4.
Answer all of the review questions related to each chapter. (The answers
appear at the end of the chapter.) Note the questions that confuse
you and study those sections of the book again. Do not just skim
these questions! Make sure you understand completely the reason
for each answer.
5.
Try your hand at the practice exams that are included on the compa-
nion CD. The questions in these exams appear only on the CD. This
will give you a complete overview of what you can expect to see on the
real CCNP Switching exam.
6.
Test yourself using all the flashcards on the CD. There are brand new
and updated flashcard programs on the CD to help you prepare com-
pletely for the CCNP Switching exam. These are a great study tool!
The electronic flashcards can be used on your Windows computer, Pocket PC,
or Palm device.
7.
Make sure you read the “Key Terms” and “Exam Essentials” lists
at the end of the chapters. These study aids will help you finish each
chapter with the main points fresh in the your mind; they’re also helpful
as a quick refresher before heading into the testing center.
To learn every bit of the material covered in this book, you’ll have to apply
yourself regularly, and with discipline. Try to set aside the same time period
every day to study, and select a comfortable and quiet place to do so. If you
work hard, you will be surprised at how quickly you learn this material.
If you follow the steps listed above, and really study and practice the
review questions, CD exams, and electronic flashcards, it would be hard to
fail the CCNP Switching exam.

What Does This Book Cover?
This book covers everything you need to pass the CCNP Switching exam.
The following list describes what you will learn in each chapter:
Chapter 1 describes the traditional campus network model and moves
into the new emerging campus model. Layer 2, 3, and 4 switching is
also discussed. In addition, this chapter discusses the Cisco three-layer
model, the Cisco switching product line, and how to build switch and
core blocks.
Chapter 2 describes the various Ethernet media types and how to log
in and configure both a set-based and IOS-based Cisco Catalyst
switch.
Chapter 3 covers VLANs—how they work and how to configure them
in a Cisco internetwork. Trunking and VLAN Trunk Protocol (VTP)
are described and implemented.
Chapter 4 gives you an in-depth look at the Spanning Tree Protocol
(STP), its timers, and how to configure STP in a switch.
Chapter 5 shows you how to configure STP timers and includes a dis-
cussion of root bridge selection. Redundant links with STP are also
covered.
Chapter 6 covers Inter-Switch Link (ISL) routing. Both internal route
processors and external route processors are covered, as well as how
to configure both internal and external route processors to connect
multiple VLANs.
Chapter 7 provides the fundamentals of Multi-Layer Switching on
both internal and external route processors. In addition to covering
IP routing with MLS, we show you how to configure the MLS
engine.
Chapter 8 covers the background of multicast addresses and how to
translate from a layer 3 address to a layer 2 multicast address. This
chapter also covers IGMP and CGMP.
Chapter 9 is about configuring multicast in a Cisco internetwork.
Enabling multicast, joining a multicast group, and enabling CGMP
are also covered.
