ISCW实验2:配置PPPoE与客户端_ADSL配置
 
试验预备知识:
首先建议大家先了解ATM是什么?了解一下ATM周边知识点,给出如下两个链接
 
实验过程:
第一步  ATM1的预配置
ATM1(config)#username cisco password cisco
ATM1(config)#int f3/0
ATM1(config-if)#pppoe enable
ATM1(config-if)#no sh
ATM1(config)#
第二步  配置VPDN
ATM1(config)#vpdn enable
ATM1(config)#vpdn-group adsl
ATM1(config-vpdn)#request-dialin
ATM1(config-vpdn-req-in)#protocol pppoe
% PPPoE config from vpdn-group is converted to pppoe-profile based config.
% Continue PPPoE configuration under 'bba-group pppoe global'
ATM1(config-vpdn-req-in)#exit
ATM1(config-vpdn)#exit
第三步  配置BBA-Group
ATM1(config)#bba-group pppoe global
ATM1(config-bba-group)#virtual-template 1
ATM1(config-bba-group)#exit
第四步  配置Virtual-Template接口
ATM1(config)#interface virtual-template 1
ATM1(config-if)#ip add 10.0.0.1 255.255.255.0
ATM1(config-if)#encapsulation ppp
ATM1(config-if)#ppp authentication pap
ATM1(config-if)#peer default ip address pool adsl
ATM1(config-if)#exit
ATM1(config)#ip local pool adsl 10.0.0.10 10.0.0.100
第五步  创建一个PPPoE连接,打开并连接
第六步  拨号成功后查看PPPoE的连接状态,可以看到本地的IP地址与服务器的IP地址
ISCW实验2:配置PPPoE与客户端_配置_02

第七步  同时在WireShark中抓下PPPoE拨号的过程
ISCW实验2:配置PPPoE与客户端_配置PPPoE与客户端_03

第八步  在ATM1上查看PPPoE的调试信息
ATM1#debug pppoe events
PPPoE protocol events debugging is on
