AWS re:Invent 2020: Using AWS Transit Gateway for your multicast workloads

Multicast routing quickly distributes copies of the same data from one source to multiple receivers. This is a common design for media distribution (video conferencing, for example) or for when end destinations get the same information quickly and at roughly the same time (such as a stock ticker). AWS Transit Gateway routes multicast traffic between subnets of attached VPCs and serves as a multicast router for instances, sending traffic destined for multiple receiving instances. This session covers recent AWS Transit Gateway multicast updates and includes a quick demo of passing a message from a sender to multiple subscribers.

It would be great to see how you went about setting up the environment. I'm trying to set up mine and it doesn't seem to be working as expected.
