Organization VDC networks are created and assigned to your organization VDC by a system administrator or an organization administrator. An organization administrator can view information about networks, configure network services, and more.

You can use direct, routed, internal, or cross-VDC organization virtual data center networks backed by NSX Data Center for vSphere.

You can use routed, internal, and imported organization virtual data center networks backed by NSX-T Data Center.
Table 1. Types of Organization VDC Networks
Data Center Type Network Description
Direct

An organization VDC network with a direct connection to one of the external networks that are provisioned by the system administrator and are backed by vSphere resources.

Direct networks are only supported for organization VDCs that are backed by NSX Data Center for vSphere.

Accessible by multiple organization VDCs. Virtual machines belonging to different organization VDCs can connect to and see traffic on this network.

This network provides direct layer 2 connectivity to virtual machines outside of the organization VDC. Virtual machines outside of this organization VDC can connect to virtual machines in the organization VDC directly.

Note: Only your system administrator can add a direct organization VDC network.

Can be IPv4 or IPv6.

Isolated (Internal)

Accessible only by the same organization VDC. Only virtual machines in this organization VDC can connect to and see traffic on the internal organization VDC network.

Isolated networks are supported for organization VDCs backed by NSX-T Data Center and for organization VDC NSX Data Center for vSphere.

The isolated organization VDC network provides an organization VDC with an isolated, private network that multiple virtual machines and vApps can connect to. This network provides no connectivity to virtual machines outside the organization VDC. Machines outside of the organization VDC have no connectivity to machines in the organization VDC.

Routed

Accessible only by the same organization VDC. Only virtual machines in this organization VDC can connect to this network.

This network also provides controlled access to an external network. As a system administrator or an organization administrator, you can configure network address translation (NAT), firewall, and VPN settings to make specific virtual machines accessible from the external network.

Can be IPv4 or IPv6.

Imported This network uses an existing NSX-T logical switch. Only a system administrator can import a network.
Cross-VDC

This network is part of a stretched network spanning a data center group. A data center group can comprise between two and four organization virtual data centers in a single or multisite vCloud Director deployment.

Virtual machines connected to this network are connected to the underlying stretched network.

Cross-VDC networking requires NSX Data Center for vSphere.

Can be IPv4 only.

For information about cross-VDC networks, see Managing Cross-Virtual Data Center Networking.

All steps for managing your organization VDC networks are documented assuming that you have more than one virtual data center in your environment.
