+
+In order to influence Multicast :abbr:`RPF (Reverse Path Forwarding)` lookup,
+it is possible to insert into zebra routes for the Multicast
+:abbr:`RIB (Routing Information Base)`. These routes are only used for RPF
+lookup and will not be used by ZEBRA for insertion into the kernel or for
+normal RIB processing. As such it is possible to create weird states with
+these commands.
+
+Use with caution. Most of the time this will not be necessary.

+   Insert into the Multicast RIB Route `<subnet>` with specified next-hop.
+   The distance can be specified as well if desired.
