Add a second VIP to a cloud service

Hi,

When I try to add a second VIP to my cloud service with following PowerShell command:

• Add-AzureVirtualIP -VirtualIPName Vip2 -ServiceName ***

I get the following exception:

• Add-AzureVirtualIP : BadRequest: Multiple virtualIP feature is not allowed on this deployment.

What could be wrong? Please let me know if you need more information.

Thanks.
