Generally they are shared on all compute hosts, but usually there aren't huge numbers of computes. I have not deployed routed provider networks yet, but I think the premise is great, and the /23 per rack is probably what we would do with routed provider networks for multi-rack deployments. Combining routed provider networks with Cells V2 (not sure if the two work together well, and once Cells V2 is completely done) could be quite powerful IMHO. > > A typical L2 provider network is deployed as VLANs to every host.
