This book covers a wide range of VPN technologies, including IPSec, MPLS, L2TP version 3, L2TP version 2, PPTP, and L2F. It is suited to network support engineers and architects, whose job is to provide day-to-day support for VPNs or deploy VPNs successfully in the first place.

Because of the range of coverage, and the fact that each chapter covers not only troubleshooting, but also a technical overview and configuration guidelines, this book may be of considerable assistance to CCIE candidates preparing for the Service Provider and Security exams.
