@Akilesh: Well is there any way you can do it? Please let me know, because all I was able to come up with was disable anti-spoofing and ignore neutron. I would love to have L2 only networking available just have no idea how to implement it at the moment. Right now all those provider networks are rather pain in the ***.
@Akilesh, Tiago: I don’t know/remember any specifics, but I was talking to Mark McClain last month in Budapest, and he told me that there will be possibility to create networks (or maybe ports?) and selectively choose if you want to enable only L2, or L3 as well. This is not possible as the moment I believe, since every port is bound to fixed IP, which is part of subnet. I know these information are pretty vague, but you know… 3minute chit-chat during the conference… Anyway, we could probably go through blueprints, and find something there.

Greatly apreciated. But do you know what will change with juno? What will be implemented that would allow me to do this?

If that is so… there is no good way how to do it as far as I can tell. At least no until Juno release as I was told… Even with Provider network, Neutron will still want to “manage the L3 on the part of the subnet”. Normally you can work with it, but considering you are trying to run virtual switches, I can see it can be difficult. I guess best you can do, is “hack” the IP/MAC anti-spoofing protection, let neutron to create subnet, assign an IP for the port, and then simply ignore it (since it is not enforced anymore). I’m still not sure how it will work in your case.

I think it "should" be possible but im not aware yet on how to get it working. For instance, if I would like to create some cisco csr1000v instances, and connect them. I would like to manage the subnet info on the instance side and not on neutron/nova network. Thanks.

Can you tell more about why you would like to do it? @Remo Mattei I am unaware of how to use provider network to achieve this. Can you please give us some leads.
