If Cloud Foundation is to be deployed on a VxRail stretched cluster, network settings must be captured for the second site. The table for the second site in Appendix G: Edge gateway configuration outlines the second set of settings that must be selected.
The underlying networks supporting the VxRail cluster and NSX are configured across the two sites in the stretched cluster to enable cross-site connectivity. This enables a seamless failover to the surviving site in the event of a single site failure.

To ensure uninterrupted routing services, the NSX edge devices configured as Tier-0 gateways peer with upstream routers in both locations in a stretched cluster deployment.
