You can not redistribute a default route into OSPF, at least in Cisco's OSPF implementation. OSPF on Cisco devices specifically avoids redistributing the default route into OSPF. The only way to inject a default route into OSPF is to use the default-information originate command in the appropriate OSPF process.
The default routes created using the ip route 0.0.0.0 0.0.0.0 command are not propagated by OSPF and IS-IS. Additionally, this default cannot be redistributed into OSPF or IS-IS using the redistribute command. Use the default-information originate command to generate a default route into an IS-IS or OSPF routing domain. For more detailed information on behavior of default routes with OSPF, refer to How Does OSPF Generate Default Routes?
