I'm hurt that this blue print has seen no love in 18 months: https://blueprints.launchpad.net/neutron/+spec/dhcp-options-per-subnet I need different MTUs and different domians on different subnets. It appears there is still no way to do this other than running a network node (or two if I want HA) for each subnet. Please someone tell me I'm a fool and there's an easy way to do this that I failed to find (again)... -Jon
