Configuring Route Map Redistribution
The ip redist command is used to configure the redistribution of routes from a source protocol into the IS-
IS destination protocol. This command is used on the IS-IS router that will perform the redistribution.
A source protocol is a protocol from which the routes are learned. A destination protocol is the one into
which the routes are redistributed. Make sure that both protocols are loaded and enabled before configur-
ing redistribution.
Redistribution applies criteria specified in a route map to routes received from the source protocol. There-
fore, configuring redistribution requires an existing route map. For example, the following command
configures the redistribution of RIP routes into the IS-IS network using the rip-to-isis route map:
-> ip redist rip into isis route-map rip-to-isis
RIP routes received by the ISIS router interface are processed based on the contents of the rip-to-isis route
map. Routes that match criteria specified in this route map are either allowed or denied redistribution into
the ISIS network. The route map may also specify the modification of route information before the route is
redistributed. See “Using Route Maps” on page 3-24 for more information.
To remove a route map redistribution configuration, use the no form of the ip redist into isis route-map
command. For example:
-> no ip redist rip into isis route-map rip-to-isis
Use the show ip redist command to verify the redistribution configuration:
-> show ip redist

Configuring the Administrative Status of the Route Map Redistribution
The administrative status of a route map redistribution configuration is enabled by default. To change the
administrative status, use the status parameter with the ip redist into isis route-map command. For
example, the following command disables the redistribution administrative status for the specified route
map:
-> ip redist rip into isis route-map rip-to-isis status disable
The following command example enables the administrative status:
-> ip redist rip into isis route-map rip-to-isis status enable
