You might check the linux kernels to see if it has MR entries for
each of the systems attempting to listen?

cat /proc/net/ip_mr_cache
cat /proc/net/ip_mr_vif

You might sniff to see if the routers see the pkt on the upstream
interface, and make sure it has large enough TTL.

Make sure you can unicast ping from source to all of your
sink machines.

What version of xorp are you using, and what OS?

Thanks,
Ben
