How to Change the OSPF Cost Value

How to Change the OSPF Cost Value


  • Directly change the OSPF cost value.

    <Huawei> system-view
    [Huawei] interface gigabitethernet 1/0/0
    [Huawei-GigabitEthernet1/0/0] ospf cost 65
  • Indirectly change the OSPF cost value.

    <Huawei> system-view
    [Huawei] ospf 100
    [Huawei-ospf-100] bandwidth-reference 1000

More Information

Two methods are available to change the OSPF cost. One method is to run the ospf cost command to directly change the interface cost, and the other is to change the bandwidth reference value to indirectly change the interface cost. In the second method, OSPF automatically calculates the cost according to the interface bandwidth using the following formula: Interface cost = Bandwidth reference value/Interface bandwidth. The cost is the integer portion of the calculation result. If the calculation result is less than 1, the cost is 1.
