If one is Broadcast and other side is Point to Point, On th side of Broadcast, the router will elect himself to be a DR,( because he havent hear any other guy sending himself as DR or as a BDR), So he thinks there is no one being standing in the election as DR or BDR. So he himself elect him as DR. ( And there is no BDR). He thinks the other neighbor is a DRother.
So DR listens on 224.0.0.6 for the LSA's from other DRothers and it doesnt update the databases until he receives it on 224.0.0.6, So the neighbor router is going to send updates to 224.0.0.5, So there will be no database synchronisation between them Point to Point thinks there is only one neighbor and then send updates to 224.0.0.5 or in Broadcast Type, hellos can even be sent in unicast or multicast (224.0.0.5) So when one side is Broadcast and other side is Point to Point, Neighborship will form, But databases wont be udpated, and ur control plane and forwarding plane will fail .
