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 F: Application Virtual Network configuration outlines the second set of settings that must be selected.
The underlying networks supporting the VxRail cluster and NSX-T are configured across the two sites in the stretched cluster to enable cross-site connectivity. The logical network switches and routers supporting the Application Virtual Network also extend between the two sites using this cross-site network 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-T edge devices configured as Tier-0 gateways peer with upstream routers in both locations in a stretched cluster deployment.
