Yeah. I did not set up a broadcast, just p2p. I have not tried it the odd
way yet though I can't see how this would fix this problem. But now I'm
grasping at straws. Won't be able to get to this lab again till tomorrow
night so any suggestions are welcome.

This is interesting. Normal OSPF operation on p2p links is no DR/BDR
election. If your lab questions involves forcing DR/BDR election on p2p then
that might be one reason ' ip ospf network broadcast ' was used in the
answers that you have. BTW I havn't tried this - I was just trying to add
some logic to why one would set the net type on p2p to broadcast.
You may already know and anyone will tell you that it's pointless having
DR/BDR on p2p link since there are only two interfaces talking to one
another.

Thanks, but this is not the issue. I can't see any difference in my setup
and the lab answers except they were using an ip ospf broadcast network on
the point to point R1-R2.

I have seen this a number of times.. Make sure you are using the RID of the
other router in your virtual-link statements. You can identify the RIF by
doing sh ip ospf prot on each router to gather that information. Then use
the RID of the remote router when you configure the virtual link...
HTH...
