Internet Group Management Protocol (IGMP) Multicast support on Transit Gateway multicast is now available in AWS GovCloud (US) Regions

Starting today, AWS Transit Gateway supports internet group management protocol (IGMP) multicast in AWS GovCloud (US) Regions.

IP multicast on AWS Transit Gateway helps customers build multicast applications in the cloud and distribute data across thousands of Amazon Virtual Private Cloud networks. IGMP support on Transit Gateway makes it easier for customers to scale up multicast workloads, while also simplifying the management of multicast group membership and network deployment. Customers no longer need to configure static multicast groups, sources, and receivers when building a multicast network in AWS. AWS Transit Gateway dynamically adds and deletes multicast members based on IGMP protocol interactions. Many on-premises multicast applications require IGMP to dynamically add and remove multicast group members. With native IGMP support on AWS Transit Gateway, customers can easily lift-and-shift such workloads to AWS Cloud without requiring changes to applications or network configuration. In addition, this feature also provides real-time visibility into the multicast network and enables customers to accurately keep track of group membership changes over time.
