Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 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 192.168.16.0 0.0.0.255 0
E . Router(config-router)# network 192.168.16.0 0.0.0.255 area 0
F . Router(config-router)# network 192.168.16.0 255.255.255.0 area 0

Answer: B, E

Explanation:

In the router ospf

Command, the ranges from 1 to 65535 so o is an invalid number – B is correct but A is not correct. To configure OSPF, we need a wildcard in the “network” statement, not a subnet mask. We also need to assign an area to this process – E is correct.
