[Isaku Yamahata (yamahata)]

which rule is supported depends on ODL backend.
The direction is, ODL backends should publish supported rules and networking-odl retrieaves it at startup.

[Mike Kolesnik (mkolesni)]

I think the best way is to use the feature negotiation mechanism to see if this is supported by ODL or not.
In the interim, until this is published by ODL, we can have this as a seperate cofig value or even use the features one so that if operator wants to turn it on he only has to specify it in the features config list.
