Command Syntax

area area-id stub [no-summary]

no area area-id stub [no-summary]

area-id

Identifier for the stub area; either a decimal value or an IP address.

no-summary

(Optional) Prevents an Area Border Router (ABR) from sending summary

link advertisements into the stub area.

Default

No stub area is defined.


Command Mode

Router configuration


Usage

You must configure the area stub command on all routers and access servers in the stub area. Use the

area router configuration command with the

Default

-cost keyword to specify the cost of a default

internal router sent into a stub area by an ABR.

There are two stub area router configuration commands: the stub and

Default

-cost options of the area

router configuration command. In all routers attached to the stub area, the area should be configured as

a stub area using the stub keyword of the area command. Use the

Default

-cost keyword only on an

ABR attached to the stub area. The

Default

-cost keyword provides the metric for the summary default

route generated by the ABR into the stub area.

To further reduce the number of link-state advertisements (LSAs) sent into a stub area, you can

configure the no-summary keyword on the ABR to prevent it from sending summary LSAs (LSA type 3)

into the stub area.
