Usage guidelines

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. For other cost styles, Table 49 a

pplies.
