ospfv3 cost

Function

The ospfv3 cost command sets the cost of the interface in different instances.

The undo ospfv3 cost command restores the default cost of the interface in different instances.

By default, the cost of an interface running OSPF is calculated using the following formula: Interface cost = Bandwidth reference value/Interface bandwidth where, the bandwidth reference value can be changed using the bandwidth-reference command.
