Organization virtual data center networks are created and assigned to your organization virtual data center by a system administrator or an organization administrator. An organization administrator can view information about networks, configure network services, and more.
Note: This chapter assumes that your underlying network resources are backed by NSX for vSphere. For organization virtual data centers that are backed by NSX-T Data Center, only your service provider can create organization virtual data center networks. You can use direct, routed, internal, or cross-VDC organization virtual data center networks.
| Data Center Type Network | Description |
|---|---|
| Direct | Accessible by multiple organizations. Virtual machines belonging to different organizations can connect to and see traffic on this network. This network provides direct layer 2 connectivity to virtual machines outside of the organization. Virtual machines outside of this organization can connect to virtual machines in the organization directly. Note: Only your service provider can add a direct organization VDC network. You cannot add this type of organization VDC network from the Tenant Portal. Can be IPv4 or IPv6. |
| Isolated (Internal) | Accessible only by the same organization. Only virtual machines in this organization can connect to and see traffic on the internal network. The internal network provides an organization 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. Machines outside of the organization have no connectivity to machines in the organization. Can be backed by either a network pool or an NSX-T logical switch. Note: Only your service provider can add an NSX-T organization virtual data center networks. You can add an isolated organization VDC network backed only by a network pool. Can be IPv4 only. |
| Routed | Accessible only by the same organization. Only virtual machines in this organization can connect to this network. This network also provides controlled access to an external network. System administrators and organization administrators 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. |
| 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. Can be IPv4 only. |
All steps for managing your organization virtual data center networks are documented assuming that you have more than one virtual data center.
- Add an Isolated Organization Virtual Data Center Network
You can add an isolated organization VDC network, which is accessible only by this organization. This network provides no connectivity to virtual machines outside this organization. Virtual machines outside of this organization have no connectivity to the virtual machines in the organization. [Read more] - Add a Routed Organization Virtual Data Center Network
To provide controlled access to an external network, you can add a routed organization VDC network. System administrators and organization administrators can configure network address translation (NAT), firewall, and VPN settings to make specific virtual machines accessible from the external network. [Read more] - Managing Cross-Virtual Data Center Networking
To create a network across multiple organization virtual data centers, you first group the virtual data centers, then create a stretched network in the data center group. A data center group can have either a common egress point configuration or an egress point configuration for each network fault domain. [Read more] - Edit an Organization Virtual Data Center Network
You can edit your Organization Virtual Data Center Network. [Read more] - Convert the Interface of a Network
You cannot change the interface of an existing network by editing the network properties. If you have to change the interface of a network from internal to subinterface or distributed routing, for example, you must convert the interface of the network.

If an organization virtual data center network is running out of IP addresses, you can add more addresses to its IP pool. [Read more] - View IP Addresses Used for an Organization Virtual Data Center Network
You can view a list of the IP addresses from an organization virtual data center network IP pool that are currently in use. [Read more]
