Configuring a Stub Router
When the device is overloaded and cannot forward any other packets, you can configure it as a stub router. After the router is configured as a stub router, other OSPFv3 devices do not use this device to forward data, but they can have a route to this stub router.
Context
A stub router controls traffic and instruct other OSPFv3 devices not to use it to forward data. Other OSPFv3 devices can have a route to the stub router.
The link cost in the Router LSAs generated by the stub router is set to the maximum value (65535).
Procedure
- Run system-view
The system view is displayed.
- Run ospfv3 [ process-id ]

The parameter on-startup [ interval ] specifies the interval during which the router remains a stub router.
