If Cloud Foundation is to be deployed on a VxRail stretched cluster, network settings must be captured for the second site. The table ‘2nd Site BGP Peering Networks’ and ‘2nd Site External Routers’ in the section Application Virtual Network Configuration outlines the second set of settings that need to be captured for the second site.
The underlying networks supporting the VxRail cluster and VXLAN 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. To ensure uninterrupted routing services, both sites in the stretched cluster peer with upstream routers, which means an additional pair of Edge Services Gateways need to be deployed at the second site, and the second set of Edge Services Gateways need to form an eBGP peering relationship with routers in the second site.
