關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

虛擬專用撥號網路(VPDN)允許專用網路撥入服務跨越到遠端訪問伺服器（定義為L2TP訪問集中器[LAC]）。 當點對點通訊協定(PPP)使用者端撥入LAC時，LAC判斷其應該將該PPP作業階段轉送到該使用者端的L2TP網路伺服器(LNS)，然後由該伺服器驗證使用者並開始PPP交涉。PPP設定完成後，所有幀都通過LAC傳送到客戶端和LNS。

此組態範例允許您對VPDN使用RADIUS驗證。LAC查詢RADIUS伺服器，確定轉發使用者的LNS，並建立適當的隧道。

有關VPDN的詳細資訊，請參閱瞭解VPDN。

必要條件

需求

本文件沒有特定需求。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

  • Cisco Secure ACS UNIX版本2.x.x及更高版本或Merit RADIUS

  • Cisco IOS®軟體版本11.2及更新版本

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景資訊

在本示例中，使用者為「jsmith@hp.com」，密碼為「test」。 當「jsmith@hp.com」撥入ISP路由器時，ISP路由器會將「hp.com」使用者ID傳送到ISP RADIUS伺服器。ISP伺服器找到「hp.com」使用者ID並將其隧道ID(「isp」)、家庭網關(HGW)路由器的IP地址(10.31.1.50)、網路接入伺服器(NAS)密碼(「hello」)和網關密碼(「there」)傳送回ISP路由器。

ISP路由器發起隧道並連線到10.31.1.50 HGW路由器，後者在本地對使用者「hp-gw」進行身份驗證，並將使用者id「isp」(「hello」)的密碼轉發到HGW RADIUS伺服器。建立通道後，ISP路由器將轉發到HGW路由器，並在HGW伺服器上驗證該使用者撥號的使用者標識(「jsmith@hp.com」)和密碼（「測試」）。在本示例中，ISP路由器稱為「Koala」，HGW路由器稱為「snetches」。
