Setting a Link Cost for an OSPF Interface

Setting a Link Cost for an OSPF Interface

Context

You can manually set a link cost for an OSPF interface or allow OSPF to automatically calculate the cost according to the interface bandwidth. The calculation formula is as follows:

Cost of an interface = Bandwidth reference value/Interface bandwidth.

The integer of the calculated result is used as the cost of the interface. If the calculated result is smaller than 1, the cost value is 1. Changing the bandwidth reference value can change the cost of an interface. To manually set the link cost or change the bandwidth reference value, perform the following steps.

Procedure

  • Set a link cost for an OSPF interface.
    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The OSPF interface view is displayed.

    3. (Optional) On an Ethernet interface, run undo portswitch

      The interface is switched to Layer 3 mode.

      By default, an Ethernet interface works in Layer 2 mode.

    4. Run ospf cost cost

      A cost is set for the OSPF interface.

  • Set a bandwidth reference value.
    1. Run system-view

      The system view is displayed.

    2. Run ospf [ process-id ]

      The OSPF process view is displayed.

    3. Run bandwidth-reference value

      A bandwidth reference value is set.

      The parameter value specifies the bandwidth reference value used for link cost calculations, in Mbit/s.

      NOTE:

      Ensure that the bandwidth reference values of switches in an OSPF process are the same.
