Assigning the routing switch to an OSPF area

Create a Normal, Stub, or Not So Stubby (NSSA) area.

Prerequisites

You must be in the router configuration context, as indicated by the switch(config-router)# prompt.

Procedure
Create an OSPF area for the routing switch using one of the following commands:

  • Create a normal area using the following command: area <area-id>. For command details, see area <AREA-ID>.

  • Create a stub area using the following command: area <area-id> stub. For command details, see area <AREA-ID> stub.

  • Create a Not-So-Stubby-Area using the command: area <area-id> nssa. For command details, see area <AREA-ID> nssa.

For example, the following command creates a normal area with an area identifier of 10.1.1.1. Area identifier could alternatively be entered in decimal format such as 1.
