Routing Information Protocol (RIP)
– 827 –
metric-value - Metric value assigned to all external routes for the specified
protocol. (Range: 1-16)
Default Setting
redistribution - none
metric-value - set by the
default-metric command
Command Mode
Router Configuration
Command Usage
◆
When a metric value has not been configured by the redistribute command,
the default-metric command 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.
Console(config-router)#redistribute ospf metric 3
Console(config-router)#
This example redistributes static routes and sets the metric for all of these routes to
a value of 3.
Console(config-router)#redistribute static metric 3
Console(config-router)#
