CCNP Self-Study: Building Cisco Remote Access Networks (BCRAN), Second Edition, is a Cisco authorized, self-paced learning tool for CCNP remote access foundation learning. This book provides you with the knowledge needed to build, configure, and troubleshoot a remote-access network to interconnect central sites to branch offices, small offices, and home offices. This book arms you with skills necessary to describe, configure, operate, and troubleshoot WAN and remote-access solutions.

This comprehensive guide presents detailed information and easy-to-grasp tutorials on the implementation, operation, planning, design, and troubleshooting of modern WAN technologies. Using this book, you learn how to control access using basic authentication and authorization configurations, how to maximize bandwidth utilization over the remote links, and how to set up virtual private networks (VPNs) using IPSec. Each chapter opens with a list of objectives to help focus your study. Figures, tables, examples, and command summaries appear throughout to help explain theories, commands, and setup sequences. Step-by-step configuration instructions make enabling the various technologies easy. Key terms are highlighted and defined throughout for simple reference and review. Finally, each chapter concludes with a summary to help review key concepts and review questions to reinforce your understanding of what was covered.

Whether you are preparing for CCNP certification or simply want to gain a better understanding of WAN technology deployment, you will benefit from the foundation information presented in this book.
