In the following exhibit, you have one OSPF area and want to populate the default route to all routers in the OSPF area. Which command would you use?

A. RouterA(config)# ip route 0.0.0.0 0.0.0.0 serial 0/0
B. RouterA(config-router)# default-route originate
C. RouterA(config-router)# default-information originate
D. RouterA(config-router)# network 0.0.0.0 0.0.0.0 area 0

C. The command default-information originate will propagate a default route originating from router 172.16.1.1. All OSPF routers will calculate their default routes back to this router.
