As a VMware Cloud Director service provider, you can use provider gateways to expose the IP spaces that you allocate to tenants by creating IP space uplinks.

Starting with version 10.4.1, importing an NSX Tier-0 Gateway to VMware Cloud Director is replaced by adding a provider gateway.

Unlike tier-0 gateways that you can dedicate to specific edge gateways, you can dedicate a provider gateway to an organization by making the provider gateway private. This makes possible connecting more than one edge gateway to a single private provider gateway.

As a service provider, you can use provider gateways to expose the IP spaces that you allocate to tenants by creating IP space uplinks. Associating IP spaces with a provider gateway increases tenant visibility and provides control over default service configuration, control over routing rules, and dynamic routing configuration.

Organization administrators can view general information about the IP spaces to which their organization has access through IP uplinks, and a diagram for the network topology that includes both the provider gateways and the edge gateways in their environment.
