  <p>
  After you perform this action, the subnet no longer uses the routes in the route table. Instead, it uses the
  routes in the VPC's main route table. For more information about route tables, see <a
  href="https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Route_Tables.html">Route Tables</a> in the
  <i>Amazon Virtual Private Cloud User Guide</i>.
