Description
Specify a set of bandwidth threshold values and
associated metric values for an IS-IS interface or a group of interfaces
configured under IS-IS interface-group. Depending on the
combined bandwidth of the member interfaces, IS-IS advertises the
specified metric value for the interface. When the cumulative bandwidth
of an interface group changes, Junos OS automatically sets the interface
metric to the value associated with the appropriate bandwidth threshold
value. We recommend a maximum of 3 sets of bandwidth threshold values
and associated metric values for easy interface management.
You must also configure a default static metric value
for the interface or topology with the bandwidth-based-metric statement. Junos OS uses this value to calculate the cost of a route
from the IS-IS interface or topology if the bandwidth for the interface
is higher than any of the specified bandwidth threshold values. In
case you have not configured the default static metric value IS-IS
calculates the metric based on the reference-bandwidth.
Options
| bandwidth threshold | Specify the bandwidth threshold in bits per second.
|
| metric metric metric | Specify a metric value to associate with a specific bandwidth value.
