ISCW实验3：配置Cisco PPPoE Server和Cisco PPPoE Client

corbie

试验拓扑介绍：两台路由器，通过ATM1和ATM2桥接，左边为R1，右边为R2。R1配置为PPPOE SERVER ，R2配置为PPPOE CLIENT。
试验要求：通过ATM1和ATM2，二层桥接，R2发送拨号请求，经过ATM2--DSLAM-AMT1从R1处获得IP地址

实验过程：
第一步  配置R1为PPPoE客户端
R1(config)#int f0/0
R1(config-if)#pppoe enable  接口下开启pppoe协议
R1(config-if)#no sh
R1(config-if)#
R1(config-if)#pppoe-client dial-pool-number 1 定义组名
R1(config-if)#exit
R1(config)#
R1(config)#interface Dialer0  虚拟接口Dialer0
R1(config-if)#ip address negotiated
R1(config-if)#
R1(config-if)#encapsulation ppp  封装PPP
R1(config-if)#dialer pool 1
R1(config-if)#ppp chap hostname cisco   配置拨号上去加密方式和密钥  0代表为加密强度
R1(config-if)#ppp chap password 0 cisco
R1(config-if)#exit
R1(config)#
R1(config)#ip route 0.0.0.0 0.0.0.0 Dialer0 指定一条默认路由，下一跳为dialer0
第二步  配置R2为Aggregation路由
R2(config)#username cisco password cisco
R2(config)#
R2(config)#vpdn enable
R2(config)#vpdn-group 1
R2(config-vpdn)#accept-dialin
R2(config-vpdn-acc-in)#protocol pppoe
% PPPoE config from vpdn-group is converted to pppoe-profile based config.
% Continue PPPoE configuration under 'bba-group pppoe global'
% PPPoE config from vpdn-group is converted to pppoe-profile based config.
% Continue PPPoE configuration under 'bba-group pppoe global'
R2(config-vpdn-acc-in)#exit
R2(config-vpdn)#bba-group pppoe global
R2(config-bba-group)#virtual-template 1
R2(config-bba-group)#exit
R2(config)#
R2(config)#int f0/0
R2(config-if)#no ip add
R2(config-if)#pppoe enable
R2(config-if)#no sh
R2(config-if)#
R2(config-if)#int virtual-template 1
R2(config-if)#ip add 10.0.0.1 255.255.255.0
R2(config-if)#peer default ip address pool cisco
R2(config-if)#ppp authentication chap
R2(config-if)#exit
R2(config)#ip local pool cisco 10.0.0.10 10.0.0.20
第三步  配置ATM1
ATM1(config)#no ip routing
ATM1(config)#
ATM1(config)#int f0/0
ATM1(config-if)#no ip add
ATM1(config-if)#no sh
ATM1(config-if)#bridge-group 1
ATM1(config-if)#
ATM1(config-if)#int atm1/0
ATM1(config-if)#no ip add
ATM1(config-if)#no sh
ATM1(config-if)#bridge-group 1
ATM1(config-if)#pvc 1/100
ATM1(config-if-atm-vc)#encapsulation aal5snap
ATM1(config-if-atm-vc)#
ATM1(config-if-atm-vc)#bridge 1 protocol ieee
ATM1(config)#end
ATM1#
ATM1#show bridge group
Bridge Group 1 is running the IEEE compatible Spanning Tree protocol
   Port 4 (FastEthernet0/0) of bridge group 1 is down
   Port 5 (ATM1/0 RFC 1483) of bridge group 1 is down
第四步  配置ATM2
ATM2(config)#no ip routing
ATM2(config)#
ATM2(config)#int f0/0
ATM2(config-if)#no ip add
ATM2(config-if)#no sh
ATM2(config-if)#bridge-group 1
ATM2(config-if)#
ATM2(config-if)#int atm1/0
ATM2(config-if)#no ip add
ATM2(config-if)#no sh
ATM2(config-if)#bridge-group 1
ATM2(config-if)#pvc 2/200
ATM2(config-if-atm-vc)#encapsulation aal5snap
ATM2(config-if-atm-vc)#
ATM2(config-if-atm-vc)#bridge 1 protocol ieee
ATM2(config)#
第五步  在R1上进行PPPoE和PPP信息的调试
R1#debug ppp authentication
PPP authentication debugging is on
R1#debug pppoe events
PPPoE protocol events debugging is on
