Configuring the IS-IS Cost
When you change from one IS-IS metric style to another, the IS-IS metric value could be affected. For each interface with IS-IS
enabled, you can assign a cost or metric that is used in the link state calculation.
To change the metric or cost of the interface, use the following commands.
• Assign an IS-IS metric.
