This book follows a tiered approach toward building a working knowledge of fundamental IPsec VPN design, starting with an overview of basic IPsec business drivers and functional components. These concepts and components are then used as a foundation upon which IPsec VPN High Availability (HA) design considerations are presented. Lastly, several advanced IPsec VPN technologies that are commonly available in today's enterprise networks are presented and discussed. Within each chapter, the design concepts are presented and then reinforced with configurations, illustrations, and practical case studies where appropriate.
