    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:
    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 Route Tables in the Amazon Virtual Private Cloud User Guide .

    Examples
    This example creates a route for the specified route table. The route matches all traffic (0.0.0.0/0) and routes it to the specified Internet gateway.

            The ID of the route table for the route.
            

    :type DestinationCidrBlock: string
    :param DestinationCidrBlock: The IPv4 CIDR address block used for the destination match. Routing decisions are based on the most specific match.

    :param GatewayId: The ID of an Internet gateway or virtual private gateway attached to your VPC.

    :type DestinationIpv6CidrBlock: string
    :param DestinationIpv6CidrBlock: The IPv6 CIDR block used for the destination match. Routing decisions are based on the most specific match.
