Configuration Commands
OSFP Area Index configuration
The following table describes the Area Index Configuration commands.
Table 132 OSPF Area Index Configuration commands
Command | Description |
|
|
area | Defines the area ID of the OSPF area number. |
| Command mode: Router OSPF |
|
|
area | Defines the type of area. For example, when a virtual link has to be |
{transitstubnssa} | established with the backbone, the area type must be defined as |
| transit. |
| • |
| between routing devices. Any area that is not a stub area or |
| NSSA is considered to be transit area. |
| • |
| distributed. Typically, a stub area is connected to only one |
| other area. |
| • |
| additional capabilities. For example, routes originating from |
| within the NSSA can be propagated to adjacent transit and |
| backbone areas. External routes from outside the Autonomous |
| System (AS) can be advertised within the NSSA but are not |
| distributed into other areas. |
| Command mode: Router OSPF |
|
|
area | Configures a stub area to send a numeric metric value. All routes |
| received via that stub area carry the configured metric to |
| potentially influencing routing decisions. |
| Metric value assigns the priority for choosing the switch for default |
| route. Metric type determines the method for influencing routing |
| decisions for external routes. |
| Command mode: Router OSPF |
|
|
[no] area | Defines the authentication method, as follows: |
type {passwordmd5} | • |
| |
| • |
| trusted routing devices can participate. |
| • |
| authentication is required. |
| Command mode: Router OSPF |
|
|
area | Sets time interval between two successive SPF (shortest path first) |
| calculations of the shortest path tree using the Dijkstra’s algorithm. |
| Command mode: Router OSPF |
|
|
area | Enables the OSPF area. |
| Command mode: Router OSPF |
|
|
no area | Disables the OSPF area. |
| Command mode: Router OSPF |
|
|
no area | Deletes the OSPF area. |
