CISCO CCNA Exam – Q169

Which commands are required to properly configure a router to run OSPF and to add network to OSPF area 0? (Choose two.)

A. Router(config)# router ospf 0
B. Router(config)# router ospf 1
C. Router(config)# router ospf area 0
D. Router(config-router)# network 0
E. Router(config-router)# network area 0
F. Router(config-router)# network area 0

Correct Answers: B, E

In the router ospf command, the ranges from 1 to 65535 so o is an invalid number -> but To configure OSPF, we need a wildcard in the “network” statement, not a subnet mask. We also need to assgin an area to this process.
