OSPF Virtual Link Issue - First to answer wins iPad Mini

There was an interesting post on IEOC yesterday in regards to an OSPF virtual link. Below is the original post and questions to win at the bottom of this post.

Okay, I have never came across anything like this before. On R2 and R3 connected via serial with HDLC. OSPF network type default to P2P. I configured VL using the OSPF RIDs of both routers. R3 VL comes up and R2 VL is down. I changed just about every option which makes logical sense and nothing works. I reboot and clear process and still nothing. Out of shear desperation I changed the network-types to P2MP on both sides and voila it works. I tried testing broadcast and that doesn't work. Only difference I can find is the mask changed from /24 to /32 in the LSA...as it should. But I am not sure why this has any bearing on the VL coming up.

Any thoughts??

Here are the relevant show commands and the configurations.
