network administrator has configured a default route on Router_A but it is not being shared with adjacent Router_B and the other routers in the OSPF area. Which command will save the administrator the time and trouble of configuring this default route on Router_B and all of the other routers in the OSPF area?
Router_A(config-router)# ospf redistribute default-route
Router_B(config-router)# ospf redistribute default-route
Router_A(config-router)# default-information originate *
Router_B(config-router)# default-information originate
Router_A(config-router)# ip ospf update-default
Router_B(config-router)# ip ospf update-default
Router_A(config-router)# ospf redistribute default-route
Router_B(config-router)# ospf redistribute default-route
Router_A(config-router)# default-information originate *
Router_B(config-router)# default-information originate
Router_A(config-router)# ip ospf update-default
Router_B(config-router)# ip ospf update-default
