By adding an external network, you register vSphere network resources for vCloud Director to use. You can create organization VDC networks that connect to an external network.

You can add an IPv4 or IPv6 external network. An IPv6 external network supports both IPv4 and IPv6 subnets, and an IPv4 external network supports both IPv4 and IPv6 subnets.


A vSphere port group is available with or without VLAN trunking. Elastic port groups with static port binding ensure optimal performance.


  1. Click the Manage & Monitor tab and click External Networks in the left pane.
  2. Click the Add Network button.
  3. Configure at least one backing vSphere network, and click Next.
    1. Select the vCenter Server instance to which belongs the target vSphere network.
    2. Select the vSphere network.
    3. Click Add.
    4. (Optional) To add another vSphere network, repeat the procedure.
      Multiple vSphere networks must originate on the same type of switch, either a DVSwitch or a Standard switch. You can select only one vSphere network from each vCenter Server instance.
  4. Configure at least one subnet, and click Next.
    1. To add a subnet, click Add.
    2. Enter the network Classless Inter-Domain Routing (CIDR) settings.

      Use the format network_gateway_IP_address/subnet_prefix_length, for example,

    3. (Optional) Enter the DNS settings.
    4. Configure a static IP pool by adding at least one IP range or IP address.
    5. Click OK.
    6. (Optional) To add another subnet, repeat the procedure.
  5. Enter a name and, optionally, a description for the network and click Next.
  6. Review the network settings and click Finish.

What to do next

You can now create an organization virtual data center network that connects to the external network.
