Default global metric for ISIS
TABLE 20 Feature support table
ISIS has a default metric of 10 on the ISIS active interfaces. You can change the metric value for a
specific interface by using the isis metric command or isis ipv6 metric command. This feature
allows you to change the metric value globally for all the active ISIS interfaces using one command.
You can still configure the interface level metric. If ISIS metric is configured on the interface, it will
take the precedence over the global configuration.
Configuration steps
1. Configure router ISIS using the router isis command.
2. Go to the appropriate address-family using address-family [ipv4/ipv6] unicast
command.
3. Configure default metric using default-link-metric <value> command.
Configuration example
The following global configuration example ISIS default metric is for the IPv4 address-family. It can
be similarly configured for IPv6 address-family.
Brocade(config)#router isis
Brocade(config-isis-router)#address-family ipv4 unicast
Brocade(config-isis-router-ipv4u)# default-link-metric 40
Syntax: [no] default-link-metric value [level-1 | level-2]
The value parameter is the default-link-metric value to be set for the given address-family. This is a
required parameter for this command. There is no default value for this parameter. For metric-style
narrow: 1 to 63. For metric-style wide: 1 to 16777215.
The level parameter is an optional parameter used to set the default-metric for only one of the
levels. If this parameter is not given, the default-link-metric will be applied to both level-1 and
level-2.
The [no] version of command will revert the metric value to default, which is 10.
