Consider the following when enabling OSPFv2 on a device.
- Redistribution must be enabled on devices configured to operate as ASBRs.
- All device ports must be assigned to one of the defined areas on an OSPF device. When a port is assigned to an area, all corresponding subnets on that port are automatically included in the assignment.
-
Enter the
router ospf command in global configuration mode to enable OSPF on the device.
-
Assign the areas to which the device will be attached.
-
Assign individual interfaces to the OSPF areas.
-
Assign a virtual link to any ABR that does not have a direct link to the OSPF backbone area.
-
Refer to
Changing default settings.
