[ aws . ec2 ]



Creates a reference (route) to a prefix list in a specified transit gateway route table.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--transit-gateway-route-table-id <value>
--prefix-list-id <value>
[--transit-gateway-attachment-id <value>]
[--blackhole | --no-blackhole]
[--dry-run | --no-dry-run]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


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

The ID of the transit gateway route table.

--prefix-list-id (string)

The ID of the prefix list that is used for destination matches.

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

The ID of the attachment to which traffic is routed.

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

Indicates whether to drop traffic that matches this route.

--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 create a reference to a prefix list

The following create-transit-gateway-prefix-list-reference example creates a reference to the specified prefix list in the specified transit gateway route table.

aws ec2 create-transit-gateway-prefix-list-reference \
    --transit-gateway-route-table-id tgw-rtb-0123456789abcd123 \
    --prefix-list-id pl-11111122222222333 \
    --transit-gateway-attachment-id tgw-attach-aaaaaabbbbbb11111


    "TransitGatewayPrefixListReference": {
        "TransitGatewayRouteTableId": "tgw-rtb-0123456789abcd123",
        "PrefixListId": "pl-11111122222222333",
        "PrefixListOwnerId": "123456789012",
        "State": "pending",
        "Blackhole": false,
        "TransitGatewayAttachment": {
            "TransitGatewayAttachmentId": "tgw-attach-aaaaaabbbbbb11111",
            "ResourceType": "vpc",
            "ResourceId": "vpc-112233445566aabbc"
