Symptoms

Open Shortest Path First version 3(OSPFv3) Link link-state advertisements (LSAs) may not be re-originated from the BIG-IP system if a neighboring router sends the LSA back to the BIG-IP system.

Impact

Routes from Link LSAs generated by the BIG-IP may be missing in the OSPFv3 network.

Conditions

Blade failover occurs on a chassis, 'clear ipv6 ospf process' is run, or ospf6d crashes.

Workaround

Disable OSPFv3 on the BIG-IP system until the Link LSA has been purged from the network. To do so, remove OSPFv3 from the route domain for approximately 10 seconds and then add it back.

Fix Information

Link LSAs are correctly re-originated by the BIG-IP system when the LSAs are sent to the BIG-IP by a neighbor router.
