    Manages an EC2 Transit Gateway Route Table propagation.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const example = new aws.ec2transitgateway.RouteTablePropagation("example", {
    transitGatewayAttachmentId: exampleAwsEc2TransitGatewayVpcAttachment.id,
    transitGatewayRouteTableId: exampleAwsEc2TransitGatewayRouteTable.id,
});

    import pulumi
import pulumi_aws as aws

example = aws.ec2transitgateway.RouteTablePropagation("example",
    transit_gateway_attachment_id=example_aws_ec2_transit_gateway_vpc_attachment["id"],
    transit_gateway_route_table_id=example_aws_ec2_transit_gateway_route_table["id"])

)

func main() {

		_, err := ec2transitgateway.NewRouteTablePropagation(ctx, "example", &ec2transitgateway.RouteTablePropagationArgs{

    Direct Connect Gateway Propagation

    When propagating routes from a Direct Connect Gateway attachment, reference the transit_gateway_attachment_id attribute directly from the aws.directconnect.GatewayAssociation resource (available in v6.5.0+):

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const example = new aws.directconnect.Gateway("example", {
    name: "example",
    amazonSideAsn: "64512",

const exampleGatewayAssociation = new aws.directconnect.GatewayAssociation("example", {
    dxGatewayId: example.id,
    associatedGatewayId: exampleTransitGateway.id,
    allowedPrefixes: ["10.0.0.0/16"],
});
const exampleRouteTable = new aws.ec2transitgateway.RouteTable("example", {transitGatewayId: exampleTransitGateway.id});
// Correct: Reference the attachment ID directly from the association resource
const exampleRouteTablePropagation = new aws.ec2transitgateway.RouteTablePropagation("example", {
    transitGatewayAttachmentId: exampleGatewayAssociation.transitGatewayAttachmentId,

    NOTE: Avoid using the aws.ec2transitgateway.getDirectConnectGatewayAttachment data source to retrieve the attachment ID, as this can cause unnecessary resource recreation when unrelated attributes of the Direct Connect Gateway association change (such as allowed_prefixes). Always reference the transit_gateway_attachment_id attribute directly from the aws.directconnect.GatewayAssociation resource when available.

    VPC Attachment Propagation

    For VPC attachments, always reference the attachment resource’s id attribute directly. Avoid using data sources or lifecycle rules that might cause the attachment ID to become unknown during planning:

    import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
