案例介绍：使用ACS SERVER认证PPPOE配置

对于PPPoE的实际应用案例，我们讲解的比较少。那么这里我们则讲解一下用ACS SERVER认证PPPOE的实例.网络设计的目的:是路由器下的用户用PPPOE客户端从AAA SERVER 10.72.254.125/10.72.253.7进行认证上网.

在用ACS SERVER认证PPPOE配置的过程中，我们需要对路由器进行一下设置：

注：在用ACS SERVER认证PPPOE配置中有以下特点:

1、做了两台AAA　SERVER服务器，用户如果从主的服务器上不法认证，就会到时从的服务器上进行认证。

相关内容：

aaa group server radius pppoe

server 10.72.254.125 auth-port 1645 acct-port 1646

server 10.72.253.7 auth-port 1645 acct-port 1646

!

aaa authentication ppp default group pppoe

aaa authorization network default group pppoe

aaa accounting network default start-stop group pppoe

radius-server host 10.72.254.125 auth-port 1645 acct-port 1646 key cisco

radius-server host 10.72.253.7 auth-port 1645 acct-port 1646 key cisco

做法是：建了RADIUS组PPPOE，然后配置了两台AAA　SERVER服务器。AAA用户的认证在ACS SERVER进行了限速;AAA用户的地址池也是在AAA SERVER上进行设置的.其它参考CISCO网站.
