metric-style
Configures the metric behavior transmitted by this router and the received metric behavior that will be used for processing the SPF calculation by this router.
Syntax: metric-style {narrow | wide | transition}
no metric-style
Description: Configuring metric style determines which metric behavior received from other IS-IS routers will be processed for this router's SPF calculation, and which metric behavior will be transmitted to other IS-IS routers by this router. The metric style used by an IS-IS router can be either narrow or wide.
Use the metric-style narrow command to transmit only narrow IS-IS metrics and to only process received narrow metrics from other routers for this router's SPF calculation.
Use the metric-style wide command to transmit only wide IS-IS metrics, and to only process received wide metrics from other routers for this router's SPF calculation.
Use the metric-style transition command to transmit both narrow and wide metrics, and if both metrics are received, to process the narrow metrics for this router's SPF calculation. If only wide metrics are received, wide metrics will be used for this router's SPF calculation.
Even though both narrow and wide metrics are transmitted when setting this command to transition, only narrow metric values (0 - 63) may be configured for this router's interface metrics in order to avoid routing errors and loops if another router is using wide metrics instead of narrow. The transition setting facilitates the transitioning of a network from narrow to wide metrics.
Use the no metric-style command to configure this router for the default value.
Factory Default: Narrow.
Command Mode: Interface Configuration.
Example 1: In the following example, the metric style is set to wide for interface pos 1/1/:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface pos 1/1/1
router(config-if)#metric-style wide
router(config-if)#end
router#
Example 2: In the following example, the metric style is reset to the default of narrow for interface pos 1/1/1:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface pos 1/1/1
router(config-if)#no metric-style
router(config-if)#end
router#
