The ospfv3 flush-source-trace disable command disables OSPFv3 flush LSA source tracing globally.
The undo ospfv3 flush-source-trace disable command enables OSPFv3 flush LSA source tracing globally.
By default, OSPFv3 flush LSA source tracing is enabled globally.
Usage Scenario
If network-wide OSPFv3 LSAs are flushed, network stability will be adversely affected. In this case, source tracing must be implemented to locate the root cause of the fault immediately to minimize the impact. However, OSPFv3 itself does not support source tracing. A conventional solution is isolation node by node until the faulty node is located. The solution is complex and time-consuming. OSPFv3 flush LSA source tracing can address this problem. In the preceding scenario, OSPFv3 flush LSA source tracing packets are flooded on the network, and the node that flushed the LSAs can be queried on any device on the network, which speeds up fault locating and faulty node isolation.
