Hi Nico, I don’t think a bird has a built-in function for that. I have an experimental network connecteal network connected by bgp confederation, and I use BGP.med values for the latency of the echo link. And if the package is lost is more than 30 per cent of the bgp session can't be established because bgp requires a stable environment. I think the possible way to do that is to write some script in Python and let Python to generate some configuration to control the bird. Regards, Gaoxing Zhang Sent from my iPhone

Hello fellow bird users,
I was wondering if anyone has solved this with bird or bird plus something:
Assuming you have multiple, somewhat lossy links. Packet loss might be in the range of 0-30% on each link. I would like bird to select the current best path, based on the amount of packet loss on each link.
I've the seen the various rtt* options in babel, but the notion there seems to be more time(out) specific, rather than loss specific.
Any pointers in the right direction are appreciated.
Best regards,
Nico
