Dhiman,
Directly connected interfaces have a lower administrative distance than
routing protocols. My guess is that R3 is routing via the directly
connected interface, assuming that I33 and I22 are on the same IP subnet,
and not via OSPF.
Harold is correct, they shold be in the same area. They will never become
adjancent and effectively creating two different OSPF domains.
