IPsec Virtual Private Network Fundamentals

Chapter 8. Handling Vendor Interoperability with High Availability IPSec is a standards-based protocol, and as such, the Internet Engineering Task Force (IETF) and other standards bodies have provided substantial requirements to meet the sta...

Vendor Interoperability Impact on Peer Availability In an IPSec HA environment, it is not only critical to determine the availability of both IPSec VPN tunnel endpoints, but also to quickly determine when a tunnel endpoint has become unavailable. ...

Vendor Interoperability Impact on Path Availability It is critical in an IPSec HA design that the IPSec VPN gateways and intermediate routers between the two gateways are capable of supporting and managing the availability of the path which the IP...

Vendor Interoperability Design Considerations and Options At this point, we have covered some of the most prevalent and effective means to address site-to-site and remote-access VPN High Availability. However, the design options presented in previ...

Summary This chapter discusses several key components that compose a highly available IPSec VPN design in a multi-vendor deployment. It introduces the barriers to HA design that vendor HA interoperability presents. The chapter covers several optio...
