Use the Routing Protocol > RIP > Redistribute (Add) page to import external routing information from other routing domains (that is, directly connected routes, protocols, or static routes) into this autonomous system.
Command ParametersThe type of routes that can be imported include:
External routes will be imported from the Border Gateway Protocol (BGP) into this routing domain.
Imports routes that are established automatically just by enabling IP on an interface.
Static routes will be imported into this routing domain.
External routes will be imported from the Open Shortest Path First protocol into this routing domain.
Metric assigned to all external routes for the specified protocol. (Range: 0-16; Default: the default metric as configured on the Routing Protocol > RIP > General page.)
A route metric must be used to resolve the problem of redistributing external routes with incompatible metrics.
When a metric value has not been configured on this page, the default-metric determines the metric value to be used for all imported external routes.
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 an 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.
