Thanks Roshan.
That' what I missed..... R3 now has the deafult route from R2
because I saw the routing table in R2 with codes : D*EX
I was inclined to believe the route was from EIGRP
so OSPF should redistribute it
From your answer now I realize as:
Actaully the '*' ( candidate default) over 'D' (EIGRP)
this route for R2 is viewed as a 'default route' , not a EIGRP route
