A network administrator is trying to add a new router into an established OSPF network. The
networks attached to the new router do not appear in the routing tables of the other OSPF
routers. Given the information in the partial configuration shown below, what configuration
error is causing this problem?
Router(config)# router ospf 1
Router(config-router)# network 10.0.0.0 255.0.0.0 area 0
A.
The process id is configured improperly.
B.
The OSPF area is configured improperly.
C.
The network wildcard mask is configured improperly.
D.
The network number is configured improperly.
E.
The AS is configured improperly.
F.
The network subnet mask is configured improperly.
Explanation:
When configuring OSPF, the mask used for the network statement is a wildcard mask similar to
an access list. In this specific example, the correct syntax would have been “network 10.0.0.0
0.0.0.255 area 0.”
