Customizing OSPF
Static—Redistribute static routes to the OSPF routing process.
•
Connected—Redistribute connected routes (routes established automatically by virtue of having IP
•
enabled on the interface) to the OSPF routing process. Connected routes are redistributed as external
to the AS.
• OSPF—Redistribute routes from another OSPF routing process. Choose the OSPF process ID from
the list. If you choose this protocol, the Match options on this dialog box become visible. These
options are not available when redistributing static, connected, RIP, or EIGRP routes. Skip to Step 5.
RIP—Redistribute routes from the RIP routing process.
•
EIGRP—Redistribute routes from the EIGRP routing process. Choose the autonomous system
•
number of the EIGRP routing process from the list.
If you have chosen OSPF for the source protocol, choose the conditions used for redistributing routes
Step 5
from another OSPF routing process into the selected OSPF routing process. These options are not
available when redistributing static, connected, RIP, or EIGRP routes. The routes must match the
selected condition to be redistributed. You can choose one or more of the following match conditions:
• Internal—The route is internal to a specific AS.
External 1—Routes that are external to the autonomous system, but are imported into OSPF as Type
•
1 external routes.
• External 2—Routes that are external to the autonomous system, but are imported into OSPF as Type
2 external routes.
• NSSA External 1—Routes that are external to the autonomous system, but are imported into OSPF
as Type 2 NSSA routes.
NSSA External 2—Routes that are external to the autonomous system, but are imported into OSPF
•
as Type 2 NSSA routes.
In the Metric Value field, enter the metric value for the routes being redistributed. Valid values range
Step 6
from 1 to 16777214.
When redistributing from one OSPF process to another OSPF process on the same device, the metric will
be carried through from one process to the other if no metric value is specified. When redistributing other
processes to an OSPF process, the default metric is 20 when no metric value is specified.
Choose the Metric Type.
Step 7
Choose "1" if the metric is a Type 1 external route, or "2" if the metric is a Type 2 external route.
Enter the tag value in the Tag Value field.
Step 8
The tag value is a 32-bit decimal value attached to each external route that is not used by OSPF itself,
but may be used to communicate information between ASBRs. Valid values range from 0 to
4294967295.
Check the Use Subnets check box to enable the redistribution of subnetted routes. Uncheck this check
Step 9
box to cause only routes that are not subnetted to be redistributed.
Choose the name of the route map to apply to the redistribution entry from the Route Map drop-down
Step 10
list.
Step 11 If you need to add or configure a route map, click Manage.
The Configure Route Map dialog box appears. Click Add or Edit to define which of the routes from the
specified routing protocol are allowed to be redistributed into the target routing process. For more
