Hi guys,
I'm experiencing an issue with multicast group joins from the VEs. All of our VEs use bridged interfaces, so they should have no issue receiving multicast traffic. In fact, they receive all of the 224.0.0.0 link local stuff just fine, but that's because that is broadcasted to all interfaces without discretion.
The issue I'm hitting is that the VEs are joining 239.192.0.251 and they show that they're joined. They send traffic to the group fine, and I think the routers even think they're joined. However, they receive no packets from the group. I'm testing this with dbeacon in VEs.
However, when I put the dbeacon on the host box joining the same group, the VEs that were joined on that box now see their traffic on the group, because the ethernet bridge is like a hub showing all the multicast traffic.
So the net effect is it works on the Host, but not the VE. Does anyone know how to fix this?
Thanks,
Dan
