IP ROUTING

Configuring OSPF Areas

An autonomous system must be configured with a backbone area, designated by area identifier 0.0.0.0. By default, all other areas are created as normal transit areas.

Routers in a normal area may import or export routing information about individual nodes. To reduce the amount of routing traffic flooded onto the network, you can configure an area to export a single summarized route that covers a broad range of network addresses within the area

(page 3-295). To further reduce the amount of routes passed between areas, you can configure an area as a stub or a not-so-stubby area (NSSA).

Stub – A stub does not accept external routing information. Instead, an area border router adjacent to a stub can be

configured to send a default external

route into the stub for all destinations outside the local area or the autonomous system. This route will also be

advertised as a single entry point for traffic entering the stub. Using a stub can significantly reduce the amount of topology data that has to be exchanged over the network.
