Add a network to an organization virtual datacenter to enable its virtual machines to communicate with each other or to provide access to the Internet. A single organization virtual datacenter can have multiple networks.

Table 1. Types of Organization Virtual Datacenter Networks and Their Requirements
Organization Virtual Datacenter Network Type Description Requirements
Direct connection to an external network 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 machines outside of the organization. Virtual machines outside of this organization can connect to virtual machines within the organization directly.

Can be IPv4 or IPv6.

An external network must be accessible to your organization.
Routed organization virtual datacenter network Accessible only by this organization. Only virtual machines within this organization can connect to this network.

This network provides controlled access to an external network. System administrators and organization administrators can configure network address translation (NAT) and firewall settings to make specific virtual machines accessible from the external network.

Can be IPv4 or IPv6.

An Edge Gateway must exist in your organization VDC.
Isolated organization virtual datacenter network Accessible only by this organization. Only virtual machines within this organization can connect to and see traffic on this network.

This network provides an organization with an isolated, private network that multiple vApps can connect to. This network provides no connectivity to virtual machines outside this organization or on other networks within this organization.

Can be backed by either a network pool or an NSX-T logical switch. For information about managing NSX-T organization virtual data center networks, see vCloud Director Service Provider Admin Portal Guide.

Can be IPv4 only.

A network pool or an NSX-T logical switch must exist in your organization VDC.
Cross-VDC network

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.

For information about managing cross-virtual data center networking, see the vCloud Director Tenant Portal Guide.

A data center group must exist in your organization VDC.
