A 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
Explanation: The correct answer is Router_A(config-router)# default-information originate. This command will advertise the default route from Router_A to Router_B and all other routers in the OSPF area. It saves the administrator the time and trouble of manually configuring the default route on each router separately.
