You can add more isolated or routed networks to virtual data centers. Routed networks can be added only to virtual data centers that have a gateway.

This topic provides the steps to add a network for a virtual data center by using vCloud Air. For information about adding networks by using vCloud Director, see the following topics in vCloud Director Administrator’s Guide:

Managing Organization vDC Networks

Adding Networks to an Organization vDC

Verify that you have network administrator privileges.


If necessary, click the expand icon (Expand Virtual Data Centers Pane Icon) to display the Virtual Data Centers pane.


Select the virtual data center to which the network belongs.


Click the Networks tab.


Click Add One.

The Add Network dialog appears.


Complete the following settings for the network:



Network name

Enter a name for the gateway.


(Optional) Enter a description for the network.

Routed through VDC gateway

(Optional) Select this option to create a routed network; create a routed network when the virtual machines on the network need access to the Internet. If you do not select this option, an isolated network is added to the virtual data center.


This option is only available when the virtual data center has at least one gateway.

VDC gateway

After selecting Routed through VDC gateway, select the gateway from the drop-down list. The drop-down list contains the gateways available for the virtual data center.

Network Gateway

Enter the gateway IP address for the network.


Entering a gateway IP address is required even when adding an isolated network because isolated networks are dependent on a gateway for DHCP networking services. If you are adding an isolated network, entering a gateway address in this field does not affect the network’s isolated status.

Subnet mask

Enter the subnet mask for the IP Range for this network. When you attach a virtual machine to a network, the virtual machine gets an IP address from the IP Range created for that network.

See Allocation of IP Addresses for more information.

IP Range

Enter the IP address range for this network. Click the plus to add additional IP address ranges.


Click Add Network.
