Cant forward both Unicast and Multicast traffic to a port. RIP, IGMP, PIM

I have the IP option installed in my XSM7224S.  I am trying to create a single router testbed where I forward/route both unicast and multicast traffic.  My multicast receiver support IGMPv2.

 

Since I am a standalone device I have no PIM or RIP routing neighbors.  When I enable unicast (RIP) routing, the forwarding of multicast frames ceases. ( before I enable RIP it was  forwarding frames). 

One fundamental question I have is, is there any reason that this can not be done on a XSM7224S.  On my cisco I have to enable PIM to get this to work. I've tried but that didn't make any difference. On the XSM if I enable PIM I cant get mcast to forward, period, even without RIP configed.  It's unclear how to configure a RP and BSR in this case. 

 My config is shown below. A host on interface 1/0/13 sends both ucast and mcast UDP packets to a host on interface 1/0/14.  Unicast traffic flows but no multicast traffic flows.  I see both the IGMPv2 membership queries from the XSM to my mcast receiver and the join response.

 

 I know this is a lot to ask but any guidance is appreciated.

Thanks for your time
