Acknowledgments

Josh Loveless: Special thank you to my coauthors, Ray and Arvind! I couldn’t ask for a better team. The technical editing for this book went above and beyond my expectations. Thanks, Nick and Tianji. The feedback was fantastic! A special thanks also to the IOS/XE, IOS-XR, and NX-OS programming and product teams for making multicast a priority and for all the great materials published for multicast configuration.

Ray Blair: This project was a significant undertaking, and without the partnership of Josh and Arvind, and the support of those mentioned here and many others, this would not have been an achievable goal. I am very grateful for all your help and support in completing this book!

Thanks to my wife, Sonya, and my children, Sam, Riley, Sophie, and Regan, for your patience in the many hours I spent working on this book.

Josh and Arvind, your excellent technical knowledge and dedication to the accuracy of the content made writing this book a pleasure. I look forward to many more years as your colleague and friend.

Arvind Durai: Thanks to my wife, Monica, for encouraging me to write my fourth book. You always kept my spirits high. Thank you!!!

Ray, this is my third book with you. We go a long way back, and working with you has always been a pleasure. Josh, I appreciate your dedication in this project more than you will ever know. Every success is a result of teamwork; you both have made the experience of writing this book a pleasure. Thank you!

Thanks to Mark Davis for supporting me in all my endeavors!
