Data center routing services must be configured for the Cloud Foundation on VxRail management networks that require upstream connectivity. The management components in the management workload domain connect upstream using Layer 2 networks. At the Layer 2 and Layer 3 boundary where the VLANs terminate, any networks requiring Layer 3 services must be configured with IP addresses to enable routing.
The VI workload domains that can be constructed in a standard architecture after the deployment of the management workload domain must be serviced with routing services upstream. If the use cases for any VI workload domains that include NSX-T based networks, including Application Virtual Networks, then Border Gateway Protocol is required on the Layer 2-3 network boundary.
The best practice is to configure Border Gateway Protocol (BGP) services on the Layer 2-3 network boundary before the initial deployment of Cloud Foundation on VxRail, and establish the neighbor relationships upstream to enable connectivity to required data center services and end users, and to the external Dell-Technologies and VMware support sites.
