Suggested Answer: Explanation 🗳️
Hyper-V Network Virtrtualization runs multiple virtual networks on a physical network. And each virtual network operates as if it is running as a physical network.
The Set-NetAdaptercmdlet sets the basic properties of a network adapter such as virtual LAN (VLAN) identifier (ID) and MAC address. Thus if you add the binding parameter to the command then you will be able to install the Windows Network Virtualization Filter Driver.
Step one:
Enable Windows Network Virtualization (WNV). This is a binding that is applied to the NIC that you External Virtual Switch is bound to. This can be a physical NIC, it can be an LBFO NIC team. Either way, it is the network adapter that your External Virtual Switch uses to exit the server.
This also means that if you have multiple virtual networks or multiple interfaces that you can pick and choose and it is not some global setting.
If you have one External Virtual Switch this is fairly easy:
$vSwitch = Get-VMSwitch -SwitchType External
# Check if Network Virtualization is bound
# This could be done by checking for the binding and seeing if it is enabled
ForEach-Object -InputObject $vSwitch {
if ((Get-NetAdapterBinding -ComponentID "ms_netwnv" -InterfaceDescription $_.NetAdapterInterfaceDescription).Enabled -eq $false){
# Lets enable it
-InterfaceDescription $_.NetAdapterInterfaceDescription -ComponentID "ms_netwnv"

Enable-NetAdapterBinding -
}
}
