They won't pass routes. Partially because when you mix/match network types
the "DR" selection process must match. If one side was non-broadcast (DR)
and one side was of a point-to-point link (NO DR) I would think that the
results you got would be normal. Which IE lab was this? If you can't change
the network type of R6, it sounds like you'd need to use non-broadcast which
means the only network type you'd be able to mix/match would be broadcast.

Subject: Re: interfaces w/ OSPF network types
One issue I ran into forced a ptp link on R4 and connected to R1 which was
not allowed to have sub interfaces or network type. While adjusting the
hello timer would allow OSPF to form an adjacency it would NOT pass routes.
