If you are using VMware Cloud Director 10.4.0, to provide a fully routed network topology in a virtual data center, you can dedicate an impored tier-0 gateway to a specific NSX edge gateway.
This feature is available in VMware Cloud Director 10.4.0 and earlier versions. If you are using VMware Cloud Director 10.4.1, see Managing Provider Gateways.
In this configuration, there is a one-to-one relationship between the tier-0 gateway and the VMware Cloud Director edge gateway, and no other VMware Cloud Director edge gateways can connect to the tier-0 gateway.
An edge gateway or a VRF-lite gateway that is associated with a dedicated tier-0 gateway is part of the tenant networking stack. The provider gateway is considered a part of the VMware Cloud Director network routing domain.
Dedicating a tier-0 gateway to an VMware Cloud Director edge gateway provides tenants with additional edge gateway services, such as route advertisement management and border gateway protocol (BGP) configuration.
The tenant can decide which of the tenant networks that are attached to the edge gateway to advertise to the tier-0 gateway. This makes possible a mixture of NAT-routed and fully routed organization virtual data center networks.
You can dedicate a tier-0 gateway to an VMware Cloud Director edge gateway either during the edge gateway creation or later, by editing the edge gateway general settings.
