If, as you seem to suggest, you have native multicasting on your local
LAN then you don't need any special route to join multicast groups. You
can try doing

        mrinfo <first-hop-router>

to see if your local router is configured for multicasting; the mrinfo
would show you relevant pim/dvmrp configuration information. Also, a

        tcpdump net 224

would quickly show you if multicast traffic is present on your local
LAN segment.
