300-615 Question #23: Real Exam Question with Answer & Explanation
The correct answer is B. Disable the check of the MTU value.. The interface command ip ospf mtu-ignore disables this check of the MTU value in the OSPF DBD packets. Thus, use of this command allows the OSPF adjacency to reach the FULL state even though there is an interface MTU mismatch between two OSPF routers.
Question
Refer to the exhibit. An OSPF adjacency between Router-A and Router-B fails to reach the FULL state. Which action resolves the issue?
Exhibit
Options
- AAdjust the MTU on Router-A to 1600.
- BDisable the check of the MTU value.

- DAdjust the MTU on Router-B to 1604.
Explanation
The interface command ip ospf mtu-ignore disables this check of the MTU value in the OSPF DBD packets. Thus, use of this command allows the OSPF adjacency to reach the FULL state even though there is an interface MTU mismatch between two OSPF routers.
