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 following formula: Cost = (Reference bandwidth value /
Link bandwidth) × 10. For other cost styles, Table 50 app
lies.
