Configuring OSPF areas
OSPF supports hierarchical routing by dividing the Autonomous System into different areas.
When two or more areas exist, the backbone area (area 0.0.0.0) must always be present.
You can use any value for the OSPF area name (for example, 1.1.1.1 or 200.200.200.200).
Prerequisites
You must log on to the OSPF Router Configuration mode in the ACLI.
Procedure steps
Create and configure an OSPF area by using the following command:
ipv6 area <A.B.C.D> default-cost <cost> import <value> [import-
summaries enable] translator-role <value> type <nssa|stub>
Variable definitions
Use the data in the following table to use the
ipv6 area
command.
Variable Value
default-cost <cost> Stub default metric for this stub area.
cost is the range from 0 to 16777215. This is the metric
value applied at the indicated type of service.
To configure this option to the default value, use the
default operator with the command.
The default value is 10.
import <value> Configures the area support for importing
advertisements. The options are:
• external—Stub and nssa are both false
• noexternal—Configure the area as stub area
• nssa—Configure the area as nssa
To configure this option to the default value, use the
default operator with the command.
The default value is external.
