i want public routable ips to be assigned to instances nics i have ovs setup with gre tunnels my current working config is Per-tenant Routers with Private Networks and using l3 agent providing floating ips which floating resides on my company private ip range and i do natting on my firewall to make the instance public routable.

-if i added network interface to the network node (i have controller and network node on the same machine) connecting it directly to public network can i use provider network with GRE tunneling to map it to public network and make tenants use this network i dont have switches that supports VLANs

guidelines will be very appreciated like what need to be done on physical network and quantum configs i have a working deployment already if the new config will work side by side with the current config it will be great.

No, it is not possible to have public routable IPs directly assigned to instance NICs when the OVS plugin network type is GRE. GRE backed networks are layer-2 networks overlaid on the physical IP network. The plugin does not provide a way to bridge the overlays with the physical layer-2 network.

As your switches do not support VLANS, maybe you could use a flat provider network instead.
