The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>, both ends doing certificate-based EAP-TLS authentication only. <p/> In a next step the <b>RFC 7171 PT-EAP</b> transport protocol is used within the EAP-TTLS tunnel to determine the health of <b>carol</b> and <b>dave</b> via the <b>IF-TNCCS 2.0 </b> client-server interface compliant with <b>RFC 5793 PB-TNC</b>. The IMCs and IMVs exchange messages over the <b>IF-M</b> protocol defined by <b>RFC 5792 PA-TNC</b>. <p> <b>carol</b> passes the health test and <b>dave</b> fails. Based on these measurements the clients are connected by gateway <b>moon</b> to the "rw-allow" and "rw-isolate" subnets, respectively. </p>
