Using RIP Routes for Multicast RPF Checks

You can use the ip route-type command to specify whether RIP routes are available for only unicast forwarding protocols or only multicast reverse path forwarding (RPF) checks. Routes available for unicast forwarding appear in the unicast view of the routing table, whereas routes available for multicast RPF checks appear in the multicast view of the routing table.

ip route-type

Use to specify whether RIP routes are available only for unicast forwarding, only for multicast reverse path forwarding checks, or for both.
Use the show ip route command to view the routes available for unicast forwarding.
Use the show ip rpf-routes command to view the routes available for multicast reverse path forwarding checks.
By default, RIP routes are available for both unicast forwarding and multicast reverse path forwarding checks.
Example
host1(config)#router rip host1(config-router)#ip route-type unicast
Use the no version to restore the default value, both.
