Virtual Private Cloud OnDemand Networking Guide

What to do next
See “Default Setup for Gateways and Networks,” on page 8 in this guide for information about the settings
for routed and isolated networks.
Add a Network to a Virtual Data Center
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:

Adding Networks to an Organization vDC
Prerequisites
Verify that you have network administrator privileges.
Procedure
1
If necessary, click the expand icon ( ) to display the Virtual Data Centers pane.
2 Select the virtual data center to which the network belongs.
3 Click the Networks tab.
4 Click Add One.
The Add Network dialog appears.
5 Complete the following settings for the network:
Option Description
Network name
Enter a name for the gateway.
Description
(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.
NOTE 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.
NOTE 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,” on page 11 for more information.
IP Range
Enter the IP address range for this network. Click the plus to add
additional IP address ranges.
