OSPFv3 routes advertised by another device were deleted, and the possibly faulty device did not support OSPFv3 flush LSA source trace. Log in to the possibly faulty device. If the device is deleting routes, reset or isolate it from the network. Otherwise, check other devices. Neither of the devices displayed in the display ospfv3 flush-source-trace analysis-info command output is the faulty device. (SysProcessId=[hwOspfv3ProcessId], HostName=[hwOspfv3PurgeHostName], HostIpAddress=[hwOspfv3PurgeIpAddress], RouterID=[hwOspfv3PurgeRouterId], Area=[hwOspfv3AreaIdIndex], FlushLsaNum=[hwOspfv3FlushLsaNum], AffectedNodeNum=[hwOspfv3AffectedNodeNum], TotalNodeNum=[hwOspfv3TotalNodeNum], RuledOutDeviceNum=[hwOspfv3RuledOutDeviceNum], Interval=[hwOspfv3PurgeStatPeriod])
The local device received a flush LSA from a neighbor indicating that the OSPFv3 LSAs advertised by a third device were flushed. Possibly faulty devices do not support OSPFv3 flush LSA source tracing. In this case, log in to a possibly faulty node and check whether it is flushing LSAs. If it is flushing LSAs, reset or isolate it. If the possibly faulty node is not flushing LSAs, check other possibly faulty nodes. To check the analysis report output by OSPFv3 flush LSA source tracing, run the display ospfv3 flush-source-trace analysis-info command.

Network flapping may occur, affecting traffic forwarding.
In the alarm, the value of FlushLsaNum may be 0. The interval at which the alarm is cleared and the interval at which the value of FlushLsaNum on the faulty node is cleared are both 3600s. There may be a short period (5 minutes at most) during which the value of FlushLsaNum on the faulty node is cleared but the alarm still persists.
This is a normal situation.
