Description
Use the auto-cost enable command to enable automatic link cost calculation.
Use the undo auto-cost enable command to disable the function.
This function is disabled by default.
After automatic link cost calculation is enabled, the link cost is automatically calculated based on the
bandwidth reference value of an interface. When the cost-style is wide or wide-compatible, the cost
value of an interface is calculated by using the formula: Cost = (reference bandwidth value/link
bandwidth) × 10. When the cost style is of other types: if the interface bandwidth does not exceed 10
Mbps, the interface cost equals 60; if the interface bandwidth does not exceed 100 Mbps, the interface
cost equals 50; if the interface bandwidth does not exceed 155 Mbps, the interface cost equals 40; if the
interface bandwidth does not exceed 622 Mbps, the interface cost equals 30; if the interface bandwidth
does not exceed 2500 Mbps, the interface cost equals 20; if the interface bandwidth exceeds 2500
Mbps, the interface cost equals 10.
