What is the cause of the log messages?
A . hello packet mismatch
B . OSPF area change
C . MTU mismatch
D . IP address mismatch
Answer: A
Explanation:
The log messages indicate an OSPF error related to a mismatch area ID, which is typically caused by a hello packet mismatch. In OSPF, hello packets are used to establish and maintain neighbor relationships. If there is a discrepancy in the information contained within these packets between neighboring routers, it can lead to errors such as the one displayed in the log messages.
