It's not as simple as on Cisco..

Check out here how to configure PIM to use something else than inet.0 
for its lookups:

Essentially you'll need to copy the unicast routes to another RIB as 
well, configure PIM to use that RIB and add static route under that 
RIB only.

Another alternative commonly used in multicast-enabled NREN networks 
(and maybe elsewhere)  is to only define a multicast-only RIB 
including only those routes that are actually multicast-capable as 
given by MP-BGP multicast SAFI, static routes, direct routes, 
ospf/is-is/, etc.  This specifically excludes 98% of 280K internet 
routing table that's advertising non-MP-BGP or MP-BGP unicast-only 
routes.
