Question 537

Refer to the exhibit. R1 is not forming adjacency on a point-to-point interface. Which action resolves the issue?

    Correct Answer: B

    The debug output indicates that there is a mismatched NSSA option bit between the routers. This kind of mismatch typically occurs when the area types configured on the routers do not match. To form an OSPF adjacency, the area type configuration must be identical on both routers. Therefore, the correct action is to ensure that the area types are configured the same on each router.
