It's quite bandwidth-intensive, so we obviously don't want it broadcasting over our L2 network. According to The Rules, multicast traffic gets sent to any subscribed host interface (learned through a membership report), as well as to any router interface. This means that our router will see all the multicast on the subnet, even if none of it needs to be routed. The link between the L2 network and the router will get saturated with multicast. I suppose we could give the router a beefy 40G connection, and use QoS to handle congestion. But I was hoping to find a way to keep the multicast pushed down in the EX environment where it actually belongs. Am I missing something here?
