IPSec VPN Design [Electronic resources]

Chapter 6. Designing Fault-Tolerant IPSec VPNs

Chapter 2, "IPSec Overview," and Chapter 3, "Enhanced IPSec Features," presented the fundamental concepts of IPSec. Chapter 5, "IPSec VPN Architectures," covered IPSec VPN architectural models at a conceptual level. In the next few chapters, you will focus on the design aspects of IPSec and begin to apply mechanisms and protocols you have learned in building real-life IPSec VPNs. In this chapter, you will explore mechanisms and architectures for fault-tolerant IPSec VPN design.
