VNet Forced tunneling: cannot Set-AzureVNetGatewayDefaultSites

Hello,


I'm trying to configure forced tunneling for a virtual network following this document: http://msdn.microsoft.com/en-us/library/azure/dn835140.aspx

I alrady have a working site to site vpn from on premise endpoint and Europe West. I created a new virtual network and a site to site VPN from the same on premise endpoint and Europe North datacenter.

I followed the steps in the document to create the routing table.

The last command fails with this error 

> Set-AzureVNetGatewayDefaultSite -VNetName "VNcloudEuropeNorth" -DefaultSite "FDRozzano"
Set-AzureVNetGatewayDefaultSite : BadRequest: This operation is enabled only for the following gateway mode(s):
BrooklynLite.

    + CategoryInfo          : CloseError: (:) [Set-AzureVNetGatewayDefaultSite], CloudException
    + FullyQualifiedErrorId : Microsoft.Azure.Commands.Network.Gateway.SetAzureVNetGatewayDefaultSite


It seems that some gateway configuration is not correct.

Any help?


Thank you,

Nicola
