<p>Creates a route in a route table within a VPC.</p> <p>You must specify either a destination CIDR block or a prefix list ID. You must also specify exactly one of the resources from the parameter list.</p> <p>When determining how to route traffic, we use the route with the most specific match. For example, traffic is destined for the IPv4 address <code>192.0.2.3</code>, and the route table includes the following two IPv4 routes:</p> <ul> <li> <p> <code>192.0.2.0/24</code> (goes to some target A)</p> </li> <li> <p> <code>192.0.2.0/28</code> (goes to some target B)</p> </li> </ul> <p>Both routes apply to the traffic destined for <code>192.0.2.3</code>. 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.</p> <p>For more information about route tables, see <a href="https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Route_Tables.html">Route tables</a> in the <i>Amazon Virtual Private Cloud User Guide</i>.</p>
