Usage Guidelines

Usage Scenario

To configure an area as a stub area, run the stub command. If an area is configured as a stub area, the stub command must be run in the OSPFv3 view on all Routers in the area.

You can run the default-cost(OSPFV3) command in the OSPFv3 area view to specify the cost of the default route sent from an ABR to a stub area. This command takes effect only on an ABR.

Example

# Configure OSPFv3 area 1 as a stub area.

<HUAWEI> system-view
[~HUAWEI] ospfv3 1
[*HUAWEI-ospfv3-1] area 1
[*HUAWEI-ospfv3-1-area-0.0.0.1] stub
