Maximum Values In The Routing Table; Change The Is-Is Metric Style In One Level Only - Dell S6100 Configuration Manual

Maximum Values in the Routing Table

IS-IS metric styles support different cost ranges for the route. The cost range for the narrow metric style is 0 to 1023, while all other metric
styles support a range of 0 to 0xFE000000.

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.
