Disabling OSPFv3 LSA Aging Management

Disabling OSPFv3 LSA Aging Management


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, OSPFv3 LSA aging management is enabled by default. If the aging time in a received LSA is greater than 1800s, OSPFv3 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.

By default, the OSPFv3 LSA aging management function is enabled. To disable this function, run the lsa-age refresh disable command.


  1. Run system-view

    The system view is displayed.

  2. Run lsa-age refresh disable

    OSPFv3 LSA aging management is disabled.

  3. Run commit

    The configuration is committed.
