How to enable VPC Route Propagation

[Rajinder Singh]

Currently when we setup a new VPC we use terraform to provision all of our services.

We provision a VPC, subnets an routes.

We have to work with our networking team to setup VPC between our data center and our VPC. This step is manual.

Once VPC has been configured I want to enable route propagation in the route tables.

If I try to enable the route propagation by setting the propagating_vgws

resource "aws_route_table" "routetbl_private_1a" {
    vpc_id = "${aws_vpc.vpc.id}"
 propagating_vgws = ["${aws_vpn_gateway.vgw.id}}"]
  route {
        cidr_block = "${var.ip_all}"
        nat_gateway_id = "${aws_nat_gateway.ngw1.id}"
    }

    tags {
        Name = "${var.private_route_table_1a}"
  Environment = "${var.environment}"
    }
}

I get an error saying gateway not attached. Gateway is attached.

If I got to AWS console I can enable route propagation.

Has anyone successfully enabled route propagation on a route table yet?

Thanks

This capability is already available via aws_route 

In future route propagation may move from aws_route to aws_vpn_gateway https://github.com/hashicorp/terraform/issues/3424
