Chapter27 Configuring OSPF
Customizing OSPF
The Redistribution pane displays the rules for redistributing routes from one routing process into an
OSPF routing process. You can redistribute routes discovered by RIP and OSPF into the EIGRP routing
process. You can also redistribute static and connected routes into the EIGRP routing process. You do
not need to redistribute static or connected routes if they fall within the range of a network that has been
configured through the Setup> Networks tab.
Step2 Click Add or Edit.
Alternatively, double-clicking a table entry in the Redistribution pane (if any) opens the Add/Edit OSPF
Redistribution Entry dialog box for the selected entry.
Note All steps that follow are optional.
The Add/Edit OSPF Redistribution Entry dialog box lets you add a new redistribution rule or edit an
existing redistribution rule in the Redistribution table. Some of the redistribution rule information cannot
be changed when you are editing an existing redistribution rule.
Step3 Choose the OSPF process associated with the route redistribution entry. If you are editing an existing
redistribution rule, you cannot change this setting.
Step4 Choose the source protocol from which the routes are being redistributed. You can choose one of the
following options:
Static—Redistributes static routes to the OSPF routing process.
Connected—Redistributes connected routes (routes established automatically by virtue of having IP
address enabled on the interface) to the OSPF routing process. Connected routes are redistributed as
external to the AS.
OSPF—Redistributes 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—Redistributes routes from the RIP routing process.
EIGRP—Redistributes routes from the EIGRP routing process. Choose the autonomous system
number of the EIGRP routing process from the list.
Step5 If you have chosen OSPF for the source protocol, choose the conditions used for redistributing routes
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.
Step6 In the Metric Value field, enter the metric value for the routes being redistributed. Valid values range
from 1 to 16777214.
