Registers sources (network interfaces) with the specified transit gateway multicast group. A multicast source is a network interface attached to a supported instance that sends multicast traffic. For information about supported instances, see <a href="https://docs.aws.amazon.com/vpc/latest/tgw/transit-gateway-limits.html#multicast-limits">Multicast Considerations</a> in Amazon VPC Transit Gateways. After you add the source, use <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_SearchTransitGatewayMulticastGroups.html">SearchTransitGatewayMulticastGroups</a> to verify that the source was added to the multicast group.
