By default, the OSPF LSA aging management function is enabled. To disable this function, perform this task.
If an exception occurs in the age field of LSAs, LSAs may be aged unexpectedly, causing LSA flapping or a route calculation error. For example, the aging time of the LSA AGE is 500 seconds, and the aging time of the LSA AGE is 2500 seconds. According to the protocol, the LSA automatically ages when the LSA reaches 3600 seconds. Therefore, the LSA of the device is aged too early. To solve this problem, the OSPF LSA aging time management function is enabled by default. If the aging time in a received LSA is greater than 1800s, OSPF considers the LSA abnormal and changes the aging time to 1700s until the aging time values of all LSAs in the area become the same. In this case, routes can be calculated correctly.
