Usage Guidelines

After the stub-router command is configured on a ospf device, the device informs other devices not to use this stub router to forward data by increasing the metric (≥65535) of the links in the LSA that is generated by the device. The metric is not infinite. Therefore, the routes to this stub router still exist. The metric of the LSA links that is generated by the stub router is very high.

Note the following points when running the stub-router command:

If you run the stub-router command on a device without specifying on-startup, the FW always functions as a stub device, and the cost of the routes from this device stays at 65535.
If you run the stub-router on-startup command on a device, the device becomes a stub router after it restarts or a master/slave main control board switchover is performed and stays as a stub device for a period specified by interval. If interval is not specified, the default value (500s) takes effect.
