Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to
be functioning properly. What can you conclude from the exhibit and the show runningconfiguration command output?
Select the best response.
A.
The OSPF areas are not configured correctly.
B.
The wildcard masks for the 10.x.x.x networks are incorrect.
C.
The 172.16.x.x networks need to be connected to area 0 using virtual links.
D.
The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to
172.16.0.0/16 and data is being “black holed.”
E.
There is not enough information to make a determination.
