# Using Unicast Routes for RPF

You can specify that IS-IS, OSPF, or RIP routes be available for RPF. Routes available for RPF appear in the multicast view of the routing table.

ip route-type

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