bandwidth-reference (OSPFv3)
Function
The bandwidth-reference command sets the bandwidth reference value used to calculate the link cost.
The undo bandwidth-reference command restores the default setting.
By default, the bandwidth reference value of the link cost is 100 Mbit/s. That is, the link cost is 100000000/bandwidth.
Parameters
| Parameter | Description | Value |
|---|---|---|
| value | Specifies the bandwidth reference value used to calculate the link cost. | It is an integer ranging from 1 to 2147483648, in Mbit/s. The default value is 100 Mbit/s. |
Usage Guidelines
If the link cost is not set, OSPFv3 calculates the link cost according to the link bandwidth (Cost = Reference Value/Bandwidth). Using the ospfv3 cost command sets the cost of an interface that runs OSPFv3. The priority of the cost set through the ospfv3 cost command is higher than that of the cost set through the bandwidth-reference command.
The bandwidth-reference command can be operated on Eth-Trunk interfaces as same with on physical interfaces. If the command is run on an Eth-Trunk interface, the bandwidth of the Eth-Trunk interface is equal to the total bandwidth of all its member interfaces.
