Change the IS-IS Metric Style in One Level Only
By default, the IS-IS metric style is narrow. When you change from one IS-IS metric style to another, the
IS-IS metric value (configured with the isis metric command) could be affected.
In the following scenarios, the IS-type is either Level-1 or Level-2 or Level-1-2 and the metric style
changes.
