Do a tcpdump on both nodes. You should see the multicast packets as well as
some unicast packets to the udp port you defined. As fasr as I remember there
are three (or four?) unicast packets between any multicast packet.
If you do not see these packets, you have several options to search:
- do you use virtual machines? I have seen kvm problems with multicast
packets.
- separate subnets? Talk to your network guys to use IGMP.
- Problems with your switches? Talk to the network guys.
On the other hand, you also could use udpu (unicast) for the transport.
