IP ROUTING COMMANDS

area-id- Identifies the stub area.

(The area ID must be in the form of an IP address.)

summary - Makes an Area Border Router (ABR) send a summary link advertisement into the stub area. (Default: no summary)

Command Mode

Router Configuration

Default Setting

No stub is configured.

Command Usage

All routers in a stub must be configured with the same area ID.

Routing table space is saved in a stub by blocking Type-4 AS summary LSAs and Type 5 external LSAs. The default setting for this command completely isolates the stub by blocking Type-3 summary LSAs that advertise the default route for destinations external to the local area or the autonomous system.

Use the area default-costcommand to specify the cost of a default summary route sent into a stub by an ABR.

This router supports up to 16 total areas (either normal transit areas, stubs, or NSSAs).

Example

This example creates a stub area 10.2.0.0, and assigns all interfaces with class B addresses 10.2.x.x to the stub.

Console(config-router)#area 10.2.0.0 stub Console(config-router)#network 10.2.0.0 0.255.255.255 area 10.2.0.0 Console(config-router)#
