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 31 a
pplies.
