Cloud Foundation on VxRail leverages NSX-T edge gateways to serve as the boundary point between the physical and virtual networks. This gateway is the passageway for traffic external to the data center to communicate with the virtual workload running on Cloud Foundation on VxRail. To enable routing between the physical and virtual networks, the upstream physical network must support Border Gateway Protocol. The NSX-T edge gateways require BGP adjacency to peer with upstream routing services.
