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.

以下是路由器的配置

注：

在配置中有以下特点:
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.
