Symptoms

When OSPFv3 is configured and another router in the network performs a graceful restart, ospf6d may crash.

Impact

OSPFv3 routing will interrupted while the daemon restarts and the protocol re-converges.

Conditions

-- OSPFv3 in use. -- Graceful restart initiated by another system.

Workaround

Disabling graceful restart on other network systems will prevent ospf6d from crashing on the BIG-IP system. However, it will cause a routing interruption on a system that restarts.

Fix Information

The ospf6d daemon no longer crashes when a graceful restart occurs in the network.
