Memory might be leaked when a distribute-list is used to filter routes between OSPFv3 and the Routing Information Base (RIB). The leak may lead to a crash unrelated to memory exhaustion.


ospf6d crashes interrupt all dynamic routing using OSPFv3.


OSPFv3 in use with a distribute-list, and LSAs in the database whose prefixes will be filtered by the distribute-list.


Position the BIG-IP system in the network so there are no LSAs that need to be filtered using a distribute-list, such as in a stub area.

Fix Information

ospf6d no longer crashes when a distribute-list is configured.
