Communiaction between two different subnets

One of my friend asked a question that can we a communication be possible in point to point link with different subnet ip addresses. I replied him at the same instant yes by adding static route in it and it works fine. But what happens if OSPF or ISIS is used. Under OSPF the neighborship comes up because OSPF neighborship made on the basics of multicast address not on ip address. In case of IS-IS it works on the basics of network Id not on ip addresses.
This can really a good experience becasue in network some one can make this type of mistake and you won't be able to troubleshoot because everthing works fine in it. In the next post I will post the document for this.
