Configuring IPv4 address family route parameters
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.
Metric behavior with change in metric-style
There are two types of metric styles in ISIS, narrow metric and wide metric. The range of the metric
value is different in both of these styles. If there is a change in the metric-style configuration, the
default-link-metric will also change with it. The new value of the default-link-metric will be equal to
the minimum of a) configured value and b) the maximum value supported for the new metric-style.
If the metric style changes from narrow metric to wide metric, there will be no change in the value
of default-link-metric.
If the metric style changes from wide metric to narrow metric, and if the value of default-link-metric
is greater than 63, the default-link-metric will now take the value 63, as it is the maximum
supported in the narrow metric.
ISIS Show command
The show isis command and show ipv6 isis command output has been modified to reflect
the default-link-metric configured.

Redistributing static IPv4 routes into IPv4 IS-IS
To redistribute static IPv4 routes from the IPv4 static route table into IPv4 IS-IS routes, enter the
following command at the IPv4 IS-IS unicast address family configuration level.
Brocade(config-isis-router-ipv4u)# redistribute static
This command configures the Brocade device to redistribute all static IPv4 routes into Level-2 IS-IS
routes.
Syntax: [no] redistribute static [level-1 | level-1-2 | level-2] |
metric num | metric-type [external | internal] | route-map name
The level-1, level-1-2, and level-2 keywords restrict redistribution to the specified IPv4 IS-IS level.
