Enabling OSPFv2

A number of steps are required when enabling OSPFv2 on a device.

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.
  1. Enter the router ospf command in global configuration mode to enable OSPF on the device.
  2. Assign the areas to which the device will be attached.
  3. Assign individual interfaces to the OSPF areas.
  4. Assign a virtual link to any ABR that does not have a direct link to the OSPF backbone area.
    Refer to Changing default settings.
