bandwidth-reference (OSPFv3 view)

Use bandwidth-reference to set a reference bandwidth value for link cost calculation.

Use undo bandwidth-reference to restore the default.

Syntax

bandwidth-reference value

undo bandwidth-reference

Default

The reference bandwidth value is 100 Mbps for link cost calculation.

Views

OSPFv3 view

Predefined user roles

network-admin

Parameters

value: Specifies the reference bandwidth value for link cost calculation, in the range of 1 to 4294967 Mbps.

Usage guidelines

You can configure an OSPFv3 cost for an interface with one of the following methods:

• Configure the cost value in interface view.

• Configure a bandwidth reference value. OSPFv3 computes the cost automatically based on the bandwidth reference value by using the following formula: Interface OSPFv3 cost = Bandwidth reference value / Interface bandwidth.

  • If the calculated cost is greater than 65535, the value of 65535 is used.

  • If the calculated cost is smaller than 1, the value of 1 is used.

If no cost value is configured for an interface, OSPFv3 computes the interface cost value automatically.

Examples

# Set the reference bandwidth value to 1000 Mbps.
