How to create a network in vCloud?

To create a new Network, click Add in the Networking view as shown below:
In the dialog, select scope – your organization’s virtual data center and select the type of network to be created:

If an Edge Gateway is present, create a routed network, otherwise, a new isolated network can be created.
At the next page, if you are creating a Routed network, you will see an Edge Connection screen next. Select the relevant Edge Gateway and which type of Interface you wish to use, then select Next.
Then enter the network’s display name and Gateway address in CIDR format. In this example we use 192.168.0.1 as our Gateway:
At the next screen, allocate internal IP pools for the subnet. Enter a range in the box and select Add.
The example shows that it would include a subnet on 192.168.0.1/24, with a Gateway on 192.168.0.1 as defined above, and allocates 192.168.0.2 – 192.168.0.254.
Select Next and then you have the option of defining DNS servers at the penultimate screen but this step is not mandatory.
At the final screen, check your configuration and if everything is correct, click on Finish.
