This is not specific to (GRE) tunnel, it is common to all point-to-point
links, you can have OSPF adj over a serial link with ip unnumbered address
with different subnet masks.
When IP unnumbered is configured, routes learned through the IP unnumbered
interface have the interface as the next hop instead of the source address
of the routing update.
