Performing basic OSPF configuration

3. Assign VLAN 1001 to a VLAG.

Performing basic OSPF configuration

To begin using OSPF on the router, perform these steps.

1. Follow the rules in the “OSPF configuration rules” on page 523.

2. Enable OSPF on the router. Refer to “Enabling and disabling OSPF on the router” on page 523.

3. Assign the areas to which the router will be attached. Refer to “Assigning OSPF areas” on

page 525.

4. Assign individual interfaces to the OSPF areas. Refer to “Assigning interfaces to an area” on

page 529.

5. Assign a virtual link to any Area Border Router (ABR) that does not have a direct link to the

OSPF backbone area. Refer to “Assigning virtual links” on page 530.

6. Refer to “Changing other settings” on page 532.

OSPF configuration rules

• If a router is to operate as an Autonomous System Boundary Router (ASBR), you must enable

the ASBR capability at the system level.

• Redistribution must be enabled on routers configured to operate as ASBRs.

• All router ports must be assigned to one of the defined areas on an OSPF router. When a port is

assigned to an area, all corresponding subnets on that port are automatically included in the

assignment.

Enabling and disabling OSPF on the router

When you enable OSPF on the router, the protocol is automatically activated and you can assign

areas and modify OSPF global parameters.

If you disable OSPF, the device removes all the configuration information for the disabled protocol

from the running configuration. Moreover, when you save the configuration to the startup

configuration file after disabling one of these protocols, all the configuration information for the

disabled protocol is removed from the startup configuration file.

If you are testing an OSPF configuration and are likely to disable and re-enable the protocol, you

might want to make a backup copy of the startup configuration file containing the protocol’s

configuration information. This way, if you remove the configuration information by saving the

configuration after disabling the protocol, you can restore the configuration by copying the backup

copy of the startup configuration file onto the flash memory.
