Which three of the interfaces shown in the exhibit will participate in OSPF according to this configuration statement?
A network associate has configured OSPF with the command:City(config-router)# network 192.168.12.64 0.0.0.63 area 0After completing the configuration, the associate discovers that not all the interfaces are participating in OSPF.
The network 192.168.12.64 0.0.0.63 equals to network 192.168.12.64/26. This network has:
+ Increment: 64 (/26= 1111 1111.1111 1111.1111 1111.1100 0000)
+ Network address: 192.168.12.64
+ Broadcast address: 192.168.12.127
Therefore all interface in the range of this network will join OSPF -> B C D are correct.
