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, which is in the range of 1 to 16777214. For other cost styles, Table 29 a
pplies.
