Configuring a Global Default Metric

You can use the metric command to specify a global default metric that applies to all active IS-IS interfaces. This command enables you to avoid configuring the desired metric on each active interface individually when you want all IS-IS interfaces to have the same metric, but a different value than the individual default of 10. The global default metric applies to both level 1 and level 2 interfaces unless you restrict it to one level.

If you have configured a nondefault metric on any IS-IS interface with the isis metric command, that value overrides the global default metric.

Reference bandwidth takes precedence over both individual and global default metrics. If you have configured a reference bandwidth, the metric command has no effect on interface metrics,

You can use the following commands to verify configuration of the global default metric:

• show configuration
• show clns interface
• show clns protocol
• show isis database detail

metric

• Use to apply the same default metric value to all active IS-IS interfaces. The command affects both IPv4 and IPv6 interfaces.
• Specify whether the command applies to level 1 or level 2 interfaces. If you do not specify a level, then the metric is applied to both level 1 and level 2 interfaces.
• Example

  host1(config-router)#metric 50 level-1

• Use the no version to remove the global default value. This restores the default value of 10 to all active IS-IS interfaces except for interfaces that have been individually configured with another metric value.
