Using Unicast Routes for RPF

You can use the ip route-type command to specify that BGP routes should be available for RPF. Routes available for RPF appear in the multicast view of the routing table.

Note: This command functions the same for both IPv4 and IPv6 multicast.

ipv6 route-type

Use to specify that BGP routes are available only for unicast forwarding, only for multicast RPF checks, or for both.
Use the show ipv6 rpf-routes command to view the routes available for RPF.
By default, BGP routes are available both for unicast forwarding and multicast reverse-path forwarding checks.
Example
host1(config)#router bgp host1(config-router)#ipv6 route-type multicast
There is no no version.
See ipv6 route-type.
