You'll need to add a new bridge to your compute nodes and create a
provider network associated with that bridge. In my setup this is
simply a flat network tied to a tagged interface. In your case it
probably makes more sense to make a new VNI and create a vxlan
provider network. The routing in your switches should handle the rest.
