HyperV PVLAN question

Hi All,

Here is my question:

I configure PVLANs on VMs with powershell cmdlets Set-VMNetworkAdapterVlan, as per this posts (http://www.cdolar.com/2012/12/network-isolation-using-pvlans-in-hyperv-3-0/#more-45) or (http://hikmatkanaan.wordpress.com/2012/11/10/configuring-windows-2012-private-vlan-pvlan/).

I have a primary VLAN that is routable on the physical network.

1. I configure a VM with isolated VLAN.
2. I configure a VM with community VLAN.
3. I configure a VM with promiscuous VLAN.

All of the configuration works as expected inside HyperV. But I cant ping any of the external subnets (that are not in HyperV) from any of the VM machines that have PVLAN enabled except the VM with promiscuous mode.

Is this by design? Did I miss-configure something. I didnt see anywhere that I need to do any configuration the physical routers and switches for PVLAN to work with the external networks.

Thanks
