i am trying to work out how routing between VMs in different subnets will work in hyper-v.
If each subnet has its own dedicated physical network card does this mean i could use a cisco router with a static route configured to route between my subnets? I understand a VM rras server is an alternative?
Which would be best? Any suggestions please?

You can either use a router or a computer to provide routing for different subnets. If all the virtual machines are running on the same Hyper-V host machine, you can use a virtual machine with RRAS as alternative.

A little more info would not go astray!
If the virtual networks are external virtual networks (ie linked to physical NICs which are in different IP subnets) then a hardware router can certainly route the traffic between them. If the virtual networks are internal networks then you need a vm (with an interface in each internal network) to route between them, since a physical router will never see any of the traffic. The router vm can run any OS and any router software. A Windows client OS can do simple routing and Windows Server with RRAS will do just about anything you might need. If you don't have a Windows OS bulk licence the Linux PFSense appliance works fine in vms.

thanks Bill just what i was looking for.
These virtual networks are confusing me.
So with an external virtual network i will need a physical NIC per VM (domain)
And with an internal virtual network i will not need any other physical NICs other than the one that is in the hyper-v machine?
Is that correct?

If you want to create an External Virtual Network, you have to bind it to a physical network adapter, this is an expected behavior. Internal Virtual Network and Private Virtual Network don’t need a physical network adapter.
For more information, you can refer to:
