The ospfd is dumping a core when nssa routes are redistributed.


ospfd terminates on the BIG-IP system leading to connectivity issues until the ospfd comes up.


When a failover is initiated through the GUI on a BIG-IP high availability (HA) configuration, and a standby BIG-IP system cannot take the active role due to low HA score. The original active BIG-IP system takes back the active role.



Fix Information

ospfd no longer crashes when redistributing NSSA routes in a HA failover event.
