The Many Levels of Interoperability
Cross Vendor Interoperability
- Varied IPsec implementations make cross vendor interoperability troublesome at best
- Many critical features are often vendor specific. Products are often streamlined for usability, thus protocol extensions and other proprietary features cannot be disabled.
- C2L interop is particularly troublesome. VPN clients have become commodities, thus the goal of interoperability rare.
- Vendor support is problematic
- Potential cost savings are often consumed by implementation minutia and unpredictable stability/performance.
