路由器的通用的PPPOE拨号配置的操作方法

现在大多数家庭和宽带依然都是PPPOE方式的拨号，为了跟大家讲些路由器的pppoe拨号的操作方法和过程，下文以一个实验来说明，并且列出所有配置文件，共广大网管参考和学习。

 

 

客户机：192.168.1.1 255.255.255.0

R1：

f0/0 192.168.1.254 255.255.255.0

R2:

f1/0 1.1.1.1 255.255.255.0

我们所配置100.0.0.0网段已经被注入到对方，这就是PPP的一个特点，连接PPP的一条线路的两端无需是同一个网段，NCP会自动将对端注入到路由之中。当然，这样配置完成仅仅是拨号成功，客户端依然不能上网，需要做NAT，准确的说是PAT，这里面就不做演示了。
