IS-IS Metric Styles

The following sections provide additional information about the IS-IS metric styles.

Configuring the IS-IS Metric Style

Dell Networking OS supports the following IS-IS metric styles:

narrow (supports only type, length, and value [TLV] up to 63)

wide (supports TLV up to 16777215)

transition (supports both narrow and wide and uses a TLV up to 63)

narrow transition (accepts both narrow and wide and sends only narrow or old-style TLV)

wide transition (accepts both narrow and wide and sends only wide or new-style TLV)

Configure Metric Values

For any level (Level-1, Level-2, or Level-1-2), the value range possible in the isis metric command in INTERFACE mode changes

depending on the metric style.

The following describes the correct value range for the isis metric command.

Metric Style

Correct Value Range for the isis metric Command

0 to 16777215

wide transition

0 to 16777215

narrow transition

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.

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.
