To configure route redistribution from RIP to OSPF, the correct command incorporates the "redistribute" command under the OSPF router configuration mode, specifically mentioning the RIP protocol. This allows OSPF to learn routes from the RIP routing protocol. By specifying "metric" followed by a value, you are determining the cost of the routes being redistributed into OSPF. The subnets keyword ensures that subnet routes are also included in the redistribution process.

Using the command with "redistribute rip" correctly identifies the source protocol from which routes will be redistributed. Including parameters like "metric" allows for control over how the routes will be treated in the OSPF routing process, which is critical in preventing routing loops and ensuring optimal path selection.

Other options do not accurately represent the command used for redistribution or do not provide the correct context for implementing redistribution between these two routing protocols. For instance, simply stating "config ospf" does not initiate redistribution, nor does "router rip" configure OSPF or handle redistribution from RIP to OSPF. The option involving redistribution of OSPF itself is also not relevant in the context of moving routes from RIP to OSPF.
