Basic OSPFv2 Configuration
This section describes how to implement basic OSPF routing.
Enabling OSPF Routing For a Specific Context
Use the following configuration example to enable OSPF Routing for a specific context:
config
context context_name
router ospf
end
Notes:
•
Save your configuration as described in the
Verifying and Saving Your Configuration
chapter.
Enabling OSPF Over a Specific Interface
After you enable OSPF, specify the networks on which it will run. Use the following command to enable
OSPF:
network network_ip_address/network_mask area { area_id | area_ip_address }
The default cost for OSPF on the system is 10. To change the cost, refer to the
ip ospf cost
command in
the
Ethernet Interface Configuration Mode Commands
chapter of the
Command Line Interface Reference
.

Notes:
•
Save your configuration as described in the
Verifying and Saving Your Configuration
chapter.
Redistributing Routes Into OSPF (Optional)
Redistributing routes into OSPF means any routes from another protocol that meet specified a specified
criterion, such as route type, metric, or rule within a route-map, are redistributed using the OSPFv2 protocol
to all OSPF areas. This is an optional configuration.
config
context context_name
router ospf
redistribute { connected
| static }
end

Save your configuration as described in the
Verifying and Saving Your Configuration
