This command was introduced.

Usage Guidelines

The command is used only on an area border router attached to a stub area.

There are two stub area router configuration commands: the stub and default-cost options of the areacommand. In all routers and access servers attached to the stub area, the area should be configured as a stub area using the stub option of the area command. Use the default-cost option only on an area border router attached to the stub area. Thedefault-cost option provides the metric for the summary default route generated by the area border router into the stub area.

To remove the specified area from the software configuration, use the command no area area-id (with no other keywords). That is, no areaarea-id removes all area options, such as area authentication, area default-cost , area nssa, area range, area stub, and area virtual-link.

Examples

The following example assigns a default-cost of 20 to stub network 36.0.0.0:

interface ethernet 0
 ip address 36.56.0.201 255.255.0.0
!
router ospf 201
 network 36.0.0.0 0.255.255.255 area 36.0.0.0
 area 36.0.0.0 stub
 area 36.0.0.0 default-cost 20
