The AWS CloudFormation template in this repository, multicast.yaml, builds a simple architecture in AWS as shown in the diagram below. This can be used to demonstrate the operation of the AWS Transit Gateway multicast feature with IGMP, as described on the AWS blog.

CloudFormation now documents the igmpv2Support option to the AWS::EC2::TransitGatewayMulticastDomain resource type. The template multicast-v2.yaml uses this to automate completely the creation of the architecture. If you launch this version of the stack, you can skip ahead to the section Demonstrating multicast operation in the blog.

As built by the template, no resources are publicly accessible from the internet or from any other VPC.
