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.


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.
