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
