Thanks Claudio.
The way I see it is that RD are only local, they identify the VRF (or
rdomain) locally on the router, then the RT import / export handles
the way the routes are distributed. This permits the hub & spoke
approach for example.
If you need help on the testing side feel free to send me the code,
I'll give it a try.
