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 Multicast Considerations in Amazon VPC Transit Gateways .

After you add the source, use SearchTransitGatewayMulticastGroups to verify that the source was added to the multicast group.

See 'aws help' for descriptions of global parameters.

--transit-gateway-multicast-domain-id (string)

The ID of the transit gateway multicast domain.

--group-ip-address (string)

The IP address assigned to the transit gateway multicast group.

--network-interface-ids (list)

The group sources' network interface IDs to register with the transit gateway multicast group.



"string" "string" ...

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To register a source with a transit gateway multicast group.

The following register-transit-gateway-multicast-group-sources example registers the specified network interface group source with a multicast group.
