“This book provides readers with a solid foundation for the SRA certifi cation exam. The book goes in-depth into the topics needed for the certifi cation and provides an invaluable source of information, including the lab guides that provide the reader with great hands-on confi guration and learning for each of the topics. The book also serves as a comprehensive encyclopedia related to the design and troubleshooting of Alcatel-Lucent Service Router networks.”

—Christoffer SmøråsAlcatel-Lucent 3RP No. 552Senior Network Engineer, NetNordic

“The BGP, VPRN and Multicast are three major technologies for ISPs. This book covers them in 17 chapters, from fundamental to advanced levels for readers with different backgrounds. It not only teaches knowledge in great depth and completeness but also provides enormous study cases compiled from real–world network design scenarios. With its rich and advanced contents, the book is defi nitely a defi nitive source for preparing for the SRA exam. It is also an excellent reference book for today’s service providers for their training, researching, and engineering.”

—Grace WangAlcatel-Lucent NRSII No. 1128; Cisco CCIE NO. 14243Senior Enterprise IP Network Planner, Rogers Communications Inc.

“This book is a must-have if you are preparing for SRA certifi cation theory and lab examinations. It’s a comprehensive guide for advanced concepts of BGP, VPRN, and multicast. All concepts are thoroughly explained with examples, and [it is a] go-to-guide for ISP network engineers when designing and troubleshooting [the] ALU service router network. I will defi nitely recommend this book to ISP network professionals and believe that it will be a great addition to your library.”

—Mandeep P. SinghAlcatel-Lucent NRS II No. 1234Senior Enterprise IP Network Planner, Rogers Communications Inc.

“This book is an ideal addition to the bookshelf of all network design professionals, especially those looking to study for the Alcatel-Lucent SRA certifi cation exam. It features detailed examples, diagrams, and lab exercises combined with well-written explanations of cutting-edge technologies deployed in the market today. I for one will be referring to this book often when working on carrier networks.”

—Kieran GleesonAlcatel-Lucent SRA No. 150IP Network Design Consultant

“It’s rare to fi nd a book that includes all of the essential content that make it truly useful as both a teaching resource and a learning resource: solid, complete technical information that is presented clearly; a wealth of richly illustrated examples; and an abundance of practical confi guration examples with corresponding status printouts. Like the two predecessors in the Alcatel-Lucent self-study series, this book more than qualifi es as an exceptionally good resource for anyone studying for SRC courses and exams. It’s now one of the must-have texts for advanced–level university networking courses that I teach. I highly recommend it.”

About the Authors

Glenn Warnock earned a B.Sc. in computer science from the University of Ottawa in 1977. He became fascinated with the possibilities of networking technologies while working for Mitel, AT&T Canada, and Apple Computer. Glenn was an instructor in computer studies at Algonquin College, and teaching has always been a rewarding part of his career. He was attracted to Alcatel-Lucent in 2006 by the potential of the 7750 SR and the opportunity to help develop the Service Routing Certifi cation program. The success of both has even exceeded his optimistic expectations. Glenn can be reached on Twitter at @Glenn_Warnock.

Acknowledgments

Above all, we would like to thank all our colleagues in Alcatel-Lucent IP Routing and Transport who work on development and support of the service router product family. These products are the foundations of our careers, and the technical materials they produce are the foundation of our courses and this book. It’s great to be a part of this talented and hard-working group.

The content of this book is entirely based on the three SRC courses: BGP, VPRN and Multicast Protocols. That means this book is a joint effort of the SRC R&D group, past and present, who have all contributed to this content. The lab and busi-ness operations group makes sure that we have the lab resources and tools we need to be successful. Special thanks to Julia Kelly for her unremitting work on the Glossary. We are also greatly indebted to the Alcatel-Lucent University SRC instructors who teach and contribute to the development of these courses. We are proud to be members of this skilled and committed team.

We are very dependent on the engineering and support groups within Alcatel-Lucent who work with the products daily. Especially important to us are the IP Routing Technical Expertise Center (TEC) and IPRT Global Network Engineering groups. They are always ready to share their knowledge and help answer any questions we have.

We would not have the confi dence to publish such a book without the critical eyes of our technical reviewers. Special thanks to those in Alcatel-Lucent who found time to review our material and provide valuable input including Stephane Atangana, Sherif Awad, Colin Bookham, Steve Dyck, Mejdi Eraslan, Pavel Klepikov, Jan CG Mertens, Craig Publow, Aparna Shanker, Marcin Stawicki, Simon Tibbitts, and Camilo Uribe Velez.

We greatly appreciate the support of key customers who reviewed early proofs and provided valuable feedback and encouragement. Special thanks to Michael Anderson, Kieran Gleeson, Mandeep P Singh, Christoffer Smørås, and Grace Wang.

The job of producing the illustrations is a large and important one. Our thanks to Pat Desjardins for his quick and capable response to our demands. The team at Wiley that makes this such a professional publication is mostly invisible to us, but our thanks to Tom Dinse for providing a calm and effective interface to this skilled group.
