Default cost is based on the bandwidth.• Specify how the OSPF interface cost is calculated based on the reference bandwidth method. Thecost of an interface is calculated as Reference Bandwidth/Interface speed.ROUTER OSPFv3auto-cost [reference-bandwidth ref-bw]To return to the default bandwidth or to assign cost based on the interface type, use the no auto-cost [reference-bandwidth ref-bw] command.– ref-bw: The range is from 1 to 4294967.
