redistribute
This command imports external routing information from other routing domains (that
is, protocols or static routes) into the autonomous system. Use the
no
form to
disable this feature.
Syntax
[

redistribute
(
ospf
|

} [
metric

•
ospf
- External routes will be imported from the Open Shortest Path First
(OSPF) protocol into this routing domain.
•
static
- Static routes will be imported into this routing domain.
•
metric-value
- Metric value assigned to all external routes for the specified
protocol. (Range: 1-15)
Command Mode
Router Configuration
Default Setting
redistribution - none:
metric-value - set by the
default-metric
command (see page 42-7)
Command Usage
• When a metric value has not been configured by the
redistribute
command,
the
default-metric
command (page 42-7) sets the metric value to be used for
all imported external routes.
• A route metric must be used to resolve the problem of redistributing external
routes with incompatible metrics.
• It is advisable to use a low metric when redistributing routes from another
protocol into RIP. Using a high metric limits the usefulness of external routes
redistributed into RIP. For example, if a metric of 10 is defined for redistributed
routes, these routes can only be advertised to routers up to 5 hops away, at
which point the metric exceeds the maximum hop count of 15. By defining a
low metric of 1, traffic can follow a imported route the maximum number of
hops allowed within a RIP domain. However, using a low metric can increase
the possibility of routing loops For example, this can occur if there are multiple
redistribution points and the router learns about the same external network
with a better metric from a redistribution point other than that derived from the
original source.
Example
This example redistributes routes learned from OSPF and sets the metric for all
external routes imported from OSPF to a value of 3.
