Introduction

本文解释如何支持通过以太网接口被连接的Cisco IOS路由器的一个以太网点对点协议(PPPoE)客户端到DSL调制解调器或DSL客户端前置设备(CPE)另一个供应商。

ISP经常提供他们的用户有一个以太网接口连接到用户以太网段的DSL调制解调器和另一个接口为DSL线路连通性。在这种情况下，如果CPE为任何IP连通性或增强的功能不是可配置的在DSL， DSL调制解调器只作为网桥。这对一个PPPoE客户端PC只限制您的连接。增加Cisco IOS路由器被连接到DSL调制解调器的以太网，您能运行在Cisco路由器的PPPoE客户端IOS功能。这能连接在以太网段的多台PC被连接到Cisco IOS路由器。使用使用Cisco IOS路由器，您能提高您的DSL连接和所有IOS功能，例如安全、网络地址转换(NAT)和动态主机配置协议(DHCP)到内部主机。

PPPoE功能允许您起动在一个简单的桥接以太网连接的客户端的一次PPP会话。会话在ATM链路被传输通过被封装的以太网桥接帧。您能终止会话在市话运营商中心局或ISP Point of Presence。
