Sure. I'll grab it on next opportunity. > How OSPF learns subscriber routes? From the kernel proto?

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. > You have 'preference 10' for OSPF, this is the same as the default > preference for kernel protocol.
