On each node:

31. Restricting traffic to an adapter
Replica
On each node add a static route for the interface:
route add <destination> mask <subnet mask and gateway> if <interface> -p

32. VMQ Requires physical NICs that support VMQ
We recommend that you increase the VMQ weight for interfaces with heavy inbound traffic, such as storage and live migration networks. To do this, use the Set-VMNetworkAdapter Windows PowerShell cmdlet.
