-- Creates a route in a route table within a VPC.
--
--
-- You must specify one of the following targets: Internet gateway or virtual private gateway, NAT instance, NAT gateway, VPC peering connection, network interface, or egress-only Internet gateway.
--
-- When determining how to route traffic, we use the route with the most specific match. For example, traffic is destined for the IPv4 address @192.0.2.3@ , and the route table includes the following two IPv4 routes:
--
--     * @192.0.2.0/24@ (goes to some target A)
--
--     * @192.0.2.0/28@ (goes to some target B)
--
--
--
-- Both routes apply to the traffic destined for @192.0.2.3@ . However, the second route in the list covers a smaller number of IP addresses and is therefore more specific, so we use that route to determine where to target the traffic.
--
-- For more information about route tables, see <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Route_Tables.html Route Tables> in the /Amazon Virtual Private Cloud User Guide/ .

--
-- * 'crVPCPeeringConnectionId' - The ID of a VPC peering connection.

-- * 'crInstanceId' - The ID of a NAT instance in your VPC. The operation fails if you specify an instance ID unless exactly one network interface is attached.
--
-- * 'crEgressOnlyInternetGatewayId' - [IPv6 traffic only] The ID of an egress-only Internet gateway.
--
-- * 'crDestinationIPv6CidrBlock' - The IPv6 CIDR block used for the destination match. Routing decisions are based on the most specific match.
--
-- * 'crNatGatewayId' - [IPv4 traffic only] The ID of a NAT gateway.
--

--
-- * 'crGatewayId' - The ID of an Internet gateway or virtual private gateway attached to your VPC.
--
-- * 'crDryRun' - 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@ .
