5.9.5 Configuring Stub Routers

When a router has a heavy load and cannot forward any other packets, you can configure it as
a stub router. After the router is configured as a stub router, other OSPF routers do not use this
router to forward data but they can have a route to this stub router.
Context
A stub router is used to control traffic. It notifies OSPFv3 routers not to forward data by the stub
router, but they can have a route to the stub router.
Do as follows on the switch that runs OSPFv3:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospfv3 [ process-id ]
The OSPFv3 process view is displayed.
Step 3 Run:
stub-router [ on-startup [ interval ] ]
The stub router is configured.

Context
Do as follows on the switch that runs OSPFv3:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif interface-number
The interface view is displayed.
