The lsa-age refresh disable command disables OSPF LSA aging management.
The undo lsa-age refresh disable command enables OSPF LSA aging management.
By default, OSPF LSA aging management is enabled.
Usage Scenario
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, if the abnormal aging time is 2500s and the actual aging time is 500s, LSAs are aged prematurely. To address this problem, OSPF LSA aging management 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.
