# aws\_route

Provides a resource to create a routing table entry (a route) in a VPC routing table.

~> **NOTE on Route Tables and Routes:** Terraform currently
provides both a standalone Route resource and a [Route Table](route_table.html) resource with routes
defined in-line. At this time you cannot use a Route Table with in-line routes
in conjunction with any Route resources. Doing so will cause
a conflict of rule settings and will overwrite rules.

## Example usage:

```
resource "aws_route" "r" {
  route_table_id            = "rtb-4fbb3ac4"
  destination_cidr_block    = "10.0.1.0/22"
  vpc_peering_connection_id = "pcx-45ff3dc1"
  depends_on                = ["aws_route_table.testing"]
}
```

##Example IPv6 Usage:

```
resource "aws_vpc" "vpc" {
  cidr_block = "10.1.0.0/16"
  assign_generated_ipv6_cidr_block = true
}

resource "aws_egress_only_internet_gateway" "egress" {
  vpc_id = "${aws_vpc.vpc.id}"
}

resource "aws_route" "r" {
  route_table_id               = "rtb-4fbb3ac4"
  destination_ipv6_cidr_block  = "::/0"
  egress_only_gateway_id = "${aws_egress_only_internet_gateway.egress.id}"
}
```

## Argument Reference

The following arguments are supported:

* `route_table_id` - (Required) The ID of the routing table.
* `destination_cidr_block` - (Optional) The destination CIDR block.
* `destination_ipv6_cidr_block` - (Optional) The destination IPv6 CIDR block.
* `vpc_peering_connection_id` - (Optional) An ID of a VPC peering connection.
* `egress_only_gateway_id` - (Optional) An ID of a VPC Egress Only Internet Gateway.
* `gateway_id` - (Optional) An ID of a VPC internet gateway or a virtual private gateway.
* `nat_gateway_id` - (Optional) An ID of a VPC NAT gateway.
* `instance_id` - (Optional) An ID of an EC2 instance.
* `network_interface_id` - (Optional) An ID of a network interface.

Each route must contain either a `gateway_id`, `egress_only_gateway_id` a `nat_gateway_id`, an
`instance_id` or a `vpc_peering_connection_id` or a `network_interface_id`.
Note that the default route, mapping the VPC's CIDR block to "local", is
created implicitly and cannot be specified.

## Attributes Reference

The following attributes are exported:

~> **NOTE:** Only the target type that is specified (one of the above)
will be exported as an attribute once the resource is created.

* `route_table_id` - The ID of the routing table.
* `destination_cidr_block` - The destination CIDR block.
* `destination_ipv6_cidr_block` - The destination IPv6 CIDR block.
* `vpc_peering_connection_id` - An ID of a VPC peering connection.
* `egress_only_gateway_id` - An ID of a VPC Egress Only Internet Gateway.
* `gateway_id` - An ID of a VPC internet gateway or a virtual private gateway.
* `nat_gateway_id` - An ID of a VPC NAT gateway.
* `instance_id` - An ID of a NAT instance.
* `network_interface_id` - An ID of a network interface.
