  network from a Client VPN, the following happens:
  </p>
  <ul>
  <li>
  <p>
  The route that was automatically added for the VPC is deleted
  </p>
  </li>
  <li>
  <p>
  All active client connections are terminated
  </p>
  </li>
  <li>
  <p>
  New client connections are disallowed
  </p>
  </li>
  <li>
  <p>
  The Client VPN endpoint's status changes to <code>pending-associate</code>
  </p>
  </li>
  </ul>
