And the CCIE program itself has expanded to include various areas of specialization. Yet the IP routing protocols remain the essential foundation on which the CCIE candidate must build his or her expertise. If the foundation is weak the house will tumble. I stated in the introduction to Volume that . .as internetworks grow in size and complexity routing issues can become at once both large and subtle. Scalability and management of growth continues to be a central theme in this second volume as we move beyond the interior gateway protocols to examine both interautonomous system routing and more exotic routing issues such as multicasting and IPv6. My objective in this book is not only to help you walk away from the CCIE lab exam with one of those valued and valuable numbers after your name but also to help you develop the knowledge and skills to live up to the CCIE title. As with the first volume I want to make CCIEs not people who can pass the CCIE lab. In this vein you will find in this book more information than you will need to pass the lab but certainly all of the material is important in your career as a recognized internetworking expert. When I earned my CCIE the lab still consisted mostly of AGS routers. Certainly the lab and the nature of the exam have changed substantially since that ancient time. If anything the lab is more difficult now. Another addition to the CCIE program has been the recertification requirement. Even before I took the recertification exam for the first time people were telling me how much Volume had helped them prepare for the test particularly for IS-IS a protocol that few outside of service provider environments are exposed to. I have therefore written this second volume with not only CCIE candidates in .
