area stub

Use this command to define an OSPF area as a stub area.

Syntax

area area-id stub [no-summary]

no area area-id stub [no-summary]

`area-id`	Specifies the stub area. Valid values are decimal values or ip addresses.
no-summary	(Optional) Prevents an Area Border Router (ABR) from sending type 3 summary Link State Advertisements (LSAs) into the stub area. When this parameter is used, it means that all destinations outside of the stub area are represented by means of a default route.

If no-summary is not specified, the stub area will be able to receive LSAs.

OSPF router configuration.

This is an area that carries no external routes.

The “no” form of this command changes the stub back to a plain area.

The following example shows how to define OSPF area 10 as a stub area:

System(rw-config)->router ospf 1
System(rw-config-ospf-1)->area 10 stub
