See ‘aws help’ for descriptions of global parameters.


--destination-cidr-block <value>
--transit-gateway-route-table-id <value>
[--transit-gateway-attachment-id <value>]
[--blackhole | --no-blackhole]
[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]


--destination-cidr-block (string)

The CIDR range used for the destination match. Routing decisions are based on the most specific match.

--transit-gateway-route-table-id (string)

The ID of the route table.

--transit-gateway-attachment-id (string)

The ID of the attachment.

--blackhole | --no-blackhole (boolean)

Indicates whether traffic matching this route is to be dropped.

--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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
