When routes redistributed into OSPF are rapidly added and removed, OSPF may not reflect all of the updates in its LSA database.


The OSPF may have stale or missing LSAs for redistributed routes.


External routes, such as kernel or static, redistributed into OSPF being rapidly added and removed. This my happen when using Route Health Injection and enabling/disabling a virtual address.


Identify the OSPF process ID for the affected route domain using "ps | grep ospfd" and terminate it using the kill command. This disrupts dynamic routing using OSPF.
