Managing Redistribution Metrics

Redistribution in general is the advertisement of routes by one protocol that have been learned via another
dynamic routing protocol, a static route, or a directly connected router. It is deployed to promote interoperability
between networks running different routing protocols.
The redistribution of a route is achieved by defining a metric for the source routing protocol. As each routing
protocol calculates routes differently, care must be taken to define a metric that is understood by the protocol.
There are two types of metrics: internal and external. Both types can be assigned a value between 0 and 63.
However, to prevent external metrics from competing with internal metrics, 64 is automatically added to any
external metric. This puts external metrics in the range of 64 to 128, even though the metric value defined is only
in the range of 0 to 63.
There is no default metric for IS-IS. A metric should be defined for each routing protocol, otherwise a metric value
of zero (0) is automatically applied.
The following sections describe how to configure and manage redistribution metrics for IS-IS:
• Section 5.18.12.1, "Viewing a List of Redistribution Metrics"
• Section 5.18.12.2, "Adding a Redistribution Metric"
• Section 5.18.12.3, "Deleting a Redistribution Metric"
Section 5.18.12.1

Viewing a List of Redistribution Metrics

To view a list of redistribution metrics defined for an IS-IS area, type:
show running-config routing isis area name redistribute
Where:
• name is the unique name for a routing process that belongs to a specific router.
If metrics have been configured, a table or list similar to the following example appears:
ruggedcom# show running-config routing isis area Area_1 redistribute | tab
SOURCE IS TYPE

If no redistribution metrics have been configured, add metrics as needed. For more information, refer to
Section 5.18.12.2, "Adding a Redistribution
Section 5.18.12.2

Adding a Redistribution Metric

To add a redistribution metric for an IS-IS area, do the following:
1. Make sure the CLI is in Configuration mode.
2. Add the metric by typing:
312
METRIC
TYPE METRIC
internal 10
Metric".
