Why is a neighbour as ospf peer reachable, but as router unreachable?

The problem is that router 93.189.172.3 uses broadcast mode for that
network while router 93.189.172.85 uses ptp mode for it. You can use
'type broadcast|ptp' option in BIRD to force the same mode.

I guess these routers use different OSPF implementation?
