To Our Valued Readers:

As internetworking technologies continue to pervade nearly every aspect of public and private

industry worldwide, the demand grows for individuals who can demonstrate they possess the

skills needed to manage these technologies. Recognizing this need, Juniper Networks—the

leading provider of Internet infrastructure solutions that enable ISPs and other telecommuni-

cations companies to meet the demands of Internet growth—recently restructured its certifi-

cation program to provide a clear path for the acquisition of these skills. Sybex is proud to

have partnered with Juniper Networks and worked closely with members of the Juniper Net-

works Technical Certification Program to develop this Official Study Guide for the Juniper

Networks Certified Internet Professional certification.

Just as Juniper Networks is committed to establishing measurable standards for certifying

those professionals who work in the cutting-edge field of internetworking, Sybex is commit-

ted to providing those professionals with the means of acquiring the skills and knowledge they

need to meet those standards. It has long been Sybex’s desire to help individuals acquire the

technical knowledge and skills necessary to excel in the IT industry.

The authors and editors have worked hard to ensure that this Official Juniper Networks Study

Guide is comprehensive, in-depth, and pedagogically sound. We’re confident that this book will

exceed the demanding standards of the certification marketplace and help you, the Juniper Net-

works certification candidate, succeed in your endeavors.

Good luck in pursuit of your Juniper Networks certification!

This book is dedicated to my wife Anita, and to my daughters, Christina and Marissa.

Anita, your willingness to “step up” and take in the slack afforded me the time I

needed to complete this work; this book would not have been possible without you

in my life. I thank and commend you all for tolerating the extension cords required

to power my “pop lab” and for putting up with that pesky circuit breaker that needed

resetting every time someone used the hairdryer. Thanks for accommodating me in

this, my labor of love.
