Salvatore,

Thanks for your response. I will look at ML2.

I guess such capability will require the option of passing 'Plugin Name' to the first level API so that request can be forwarded to the right plugin. I will try to see whether ML2 works this way.
 
Thanks,
Nishant

Hi Nishant,

unfortunately Neutron at the moment supports only a single plugin for each service. This means you can only specify a single core_plugin.
If your goal is to support multiple backend technologies in your deployment, you should perhaps have a look at the ML2 where deployment of multiple drivers should be possible.
