Help with Route Reflector and BGP multipath.

[Arnaud Houdelette-Langlois]

Thanks for your answer.
That's was an expected one, but as I send routes to another router and not to the kernel i would have expected that this would not have been an issue. I will try to update bird. 
Do you know if BSD port is up to date ?
