The possible cost varies depending on the metric style supported. If you configure narrow, transition or narrow transition metric style, the cost can be a number between 0 and 63. If you configure wide or wide transition metric style, the cost can be a number between 0 and 16,777,215. FTOS supports five different metric styles: narrow, wide, transition, narrow transition, and wide transition. By default, FTOS generates and receives narrow metric values. Metrics or costs higher than 63 are not supported. To accept or generate routes with a higher metric, you must change the metric style of the IS-IS process. For example, if metric is configured as narrow, and an LSP with wide metrics is received, the route is not installed. FTOS supports the following IS-IS metric styles: Table 26-2. Metric Styles Metric Style Characteristics narrow Sends and accepts narrow or old TLVs (Type Length Value). wide Sends and accepts wide or new TLVs transition Sends both wide (new) and narrow (old) TLVs. narrow transition Sends narrow (old) TLVs and accepts both narrow (old) and wide (new) TLVs wide transition Sends wide (new) TLVs and accepts both narrow (old) and wide (new) TLVs. Cost Range Supported on IS-IS Interfaces 0 to 63 0 to 16777215 0 to 63 0 to 63 0 to 16777215 Use the following command in ROUTER ISIS mode to change the IS-IS metric style of the IS-IS process. Command Syntax metric-style {narrow [transition] | transition | wide [transition]} [level-1 | level-2] Command Mode Purpose ROUTER ISIS Set the metric style for the IS-IS process.
