Mit einem Virtual Private Dial-up Network (VPDN) kann ein privater Netzwerk-Einwahldienst über Remote-Zugriffsserver (definiert als L2TP Access Concentrator [LAC]) verteilt werden. Wenn sich ein PPP-Client (Point-to-Point Protocol) in eine LAC einwählt, legt die LAC fest, dass diese PPP-Sitzung an einen L2TP-Netzwerkserver (LNS) für diesen Client weitergeleitet werden soll, der dann den Benutzer authentifiziert und die PPP-Aushandlung startet. Nach Abschluss der PPP-Einrichtung werden alle Frames über die LAC an den Client und das LNS gesendet.
Mit dieser Beispielkonfiguration können Sie RADIUS-Authentifizierung mit VPDNs verwenden. Die LAC fragt den RADIUS-Server ab, bestimmt, welches LNS den Benutzer weiterleiten soll, und erstellt den entsprechenden Tunnel.
Weitere Informationen zu VPDNs finden Sie unter VPDN-Verständnis.
Für dieses Dokument bestehen keine speziellen Anforderungen.
Die Informationen in diesem Dokument basieren auf den folgenden Software- und Hardwareversionen:
Cisco Secure ACS UNIX Version 2.x.x oder höher oder Merit RADIUS

Die Informationen in diesem Dokument wurden von den Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen.
Weitere Informationen zu Dokumentkonventionen finden Sie unter Cisco Technical Tips Conventions.
In diesem Beispiel lautet der Benutzer "jsmith@hp.com" mit dem Kennwort "test". Wenn sich "jsmith@hp.com" beim ISP-Router anwählt, sendet der ISP-Router die "hp.com"-Benutzer-ID an den ISP RADIUS-Server. Der ISP-Server findet die "hp.com"-Benutzer-ID und sendet seine Tunnel-ID ("isp"), die IP-Adresse des HGW-Routers (10.31.1.50), das Network Access Server (NAS)-Kennwort ("hello") und das Gateway-Kennwort ("dorthin") zurück an den ISP-Router.
Der ISP-Router initiiert einen Tunnel und stellt eine Verbindung zum 10.31.1.50-HGW-Router her, der den Benutzer "hp-gw" lokal authentifiziert und das Kennwort für "isp" ("hello") an den HGW-RADIUS-Server weiterleitet. Sobald die Tunnel eingerichtet sind, leitet der ISP-Router den Router an den HGW-Router weiter, und die Benutzer-ID ("jsmith@hp.com") und das Kennwort ("test") der Benutzerwahl in diesem Benutzer werden auf dem HGW-Server authentifiziert. In diesem Beispiel wird der ISP-Router als "Koala" und der HGW-Router als "Sneetches" bezeichnet.
