Yes , We can achieve with access list to distribute only the require route info. But my doubt is what will happen if default route is redistributed to the OSPF area will it affect the OSPF routing table. If so is there any way apart from access-list as it may increase the CPU usage.
OSPF does not automatically propagate a default route (gateway of last resort or network 0.0.0.0 0.0.0.0). So, theoritcally, network 0.0.0.0 0.0.0.0 would not be installed on neighbour's routing tables.
To enable the propagation of 0.0.0.0 0.0.0.0 route, use the "default-information originate" router ospf command.
In any case, the default route (0.0.0.0 0.0.0.0) will not introduce a routing loop as long as it is originating from a single router.
