I haven't had a chance to test this version yet, but since I'm pretty sure this came about as a response to my bug report (see [Bug Workaround] BGP Route Reflector corrupting NLRI for EVPN Prefix Routes for more details), I believe this only handles forwarding Type-5 routes, not generating or installing them, since this is listed as a BGP change and not an EVPN change. I'll respond with more detail once I've had a chance to test, which may not be for a few days.
