在Cisco 2600上配置PPPoE客戶端以連線到非Cisco DSL CPE

簡介

本檔案將說明如何在透過乙太網路介面連線到DSL資料機或其他廠商的DSL使用者端裝置(CPE)的Cisco IOS®路由器上支援乙太網路上的點對點通訊協定(PPPoE)使用者端。

ISP通常為其客戶提供DSL數據機，它有一個乙太網介面連線到客戶的乙太網網段，另一個介面用於DSL線路連線。在這種情況下，如果CPE無法配置用於通過DSL的任何IP連線或增強功能，則DSL數據機僅作為網橋。這會將您的連線限製為只有一台PPPoE客戶端PC。通過新增連線到DSL數據機的乙太網的Cisco IOS路由器，您可以在思科路由器上運行PPPoE客戶端IOS功能。這樣可以將乙太網段上的多台PC連線到Cisco IOS路由器。通過使用Cisco IOS路由器，您可以增強與內部主機的DSL連線和所有IOS功能，如安全、網路地址轉換(NAT)和動態主機配置協定(DHCP)。

PPPoE功能允許您在簡單的橋接乙太網連線的客戶端上啟動PPP會話。此作業階段是透過封裝的乙太網路橋接訊框透過ATM連結傳輸。您可在本地交換運營商中心辦公室或ISP存在點終止會話。

必要條件

需求

本文件沒有特定需求。
