Redistributing Default route

Hi

Need help on the below redistribution problem

 _ _ _ _ _ _ _ _ _ _ _ _ _
| | |
| RIP | OSPF |
| | |
R1<------------>R|2<----------->R3
| | |
| | |
| _ _ _ _ _ _ _ | _ _ _ _ _ _ _ |

In the above topology
R2 is connected to R1 and R3.
R1 and R2 are running RIP,
R2 and R3 are running OSPF

R1 is sending only default route to R2 via RIP

Hence R2 has only 1 route for RIP subnets
R* 0.0.0.0/0 [120/1] via x.x.x.x, 00:00:03,

But when I am redistributing RIP into OSPF this default route is not getting
redistributed into OSPF i.e R3 is not learning this default route.

On the vice versa if default is generated in OSPF i.e by R3 and
redistributed in RIP on R2 default route is passed to R1 i.e R1 learns the
default route.

Is there any concept I am missing here ?

Why the default route is not getting redistributed into OSPF from RIP ?
