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 telecommunications companies to meet the demands of Internet growth—recently restructured its certification 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 Networks 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 committed 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 Networks 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.

Acknowledgments

There are numerous people who deserve a round of thanks for assisting with this book. I would first like to thank Jason Rogan and Patrick Ames, who got this project started in the first place, and in the case of Jason, for providing editorial services to ensure that the certification program was not compromised. I would also like to thank Mae Lum, Linda Stephenson, and Maureen Adams at Sybex for keeping me on schedule and for getting the whole thing rolling. A very big thank-you goes out to the technical editors, Peter Moyer and Josef Buchsteiner. Both Peter and Josef worked very hard to keep me and the resulting book honest.

I would also like to thank Juniper Networks and my manager, Scott Edwards, for making this effort possible through arrangements that allowed me to access, borrow, or buy the equipment needed to build the test bed that formed the basis of this book.
