Yes, my work has been on ML2 with neutron-openvswitch-agent.  I’m interested to see what Jun Park has. I might have something ready before he is available again, but would like to collaborate regardless.

Hi All,

Thanks for the response!
Amir,Mike: Is your implementation being done according to ML2 plugin

Hi Kanthi,

Just to reiterate what Kyle said, we do have an internal implementation using flows that looks very similar to security groups. Jun Park was the guy that wrote this and is looking to get it upstreamed. I think he'll be back in the office late next week. I'll point him to this thread when he's back.

Hi Kanthi:

Overall, this idea is interesting and removing those extra bridges would certainly be nice. Some people at Bluehost gave a talk at the Summit [1] in which they explained they have done something similar, you may want to reach out to them since they have code for this internally already.

The OVS plugin is in feature freeze during Icehouse, and will be deprecated in favor of ML2 [2] at the end of Icehouse. I would advise you to retarget your work at ML2 when running with the OVS agent instead. The Neutron team will not accept new features into the OVS plugin anymore.

Thanks,
Kyle
