Sure. I'll grab it on next opportunity.

Yes, subscriber routes are added to kernel by mpd5 and then imported by BIRD.
Recently, I patched mpd5 to delete subscriber route before adding new one. It
helped a bit and now inconsistency happens only few times per month.

Thanks, I'll change preference for OSPF.
