bandwidth-reference (OSPFv3)

bandwidth-reference (OSPFv3)


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.


bandwidth-reference value

undo bandwidth-reference


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 has the same function on Eth-Trunk interfaces and physical interfaces. If the command is executed on an Eth-Trunk interface, the bandwidth of the Eth-Trunk interface is the total bandwidth of all its member interfaces.


# Set the bandwidth reference value of the link cost to 1000.
