Refer to the exhibit.
Router C was configured so that it could form an adjacency with three OSPF
neighbors, one connected to each of its three physical interfaces.
Which statement is correct about router C?
A.
It is configured and functioning correctly as an OSPF internal router.
B.
It is configured and functioning correctly as an ABR attached to stub area 4.
C.
It is configured and functioning correctly as an ASBR attached to external area 4.
D.
It is configured and functioning correctly as an ABR attached to totally stubby area 4.
E.
It is not configured correctly to function as specified.
Explanation:
From the output of the “show ip ospf” command we notice 2 lines:
+ It is an area border router+ It is a stub area, no summary LSA in this area (in Area 4)
Therefore we can conclude RouterC is an ABR and it is attached to a totally stubby area (with no
summary LSA advertised).
