一、配置PPPoE Server
1、ISP的基本配置
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
Huawei\]undo info-center ena Info: Information center is disabled. \[Huawei\]sysn ISP \[ISP\]int l0 \[ISP-LoopBack0\]ip add 10.10.10.1 24 \[ISP-LoopBack0\]qu \[ISP
2、配置PPPoE地址池
ISP\]ip pool pppoe Info: It's successful to create an IP address pool. \[ISP-ip-pool-pppoe\]gateway-list 20.20.20.1 \[ISP-ip-pool-pppoe\]network 20.20.20.0 mask 255.255.255.0 \[ISP-ip-pool-pppoe\]qu 3、配置PPPoE认证用户，实现PPPoE对用户主机的认证 \[ISP\]aaa \[ISP-aaa\]local-user admin password cipher 123456 \[ISP-aaa\]local-user admin privilege level 0 \[ISP-aaa\]local-user admin service-type ppp \[ISP-aaa\]qu 4、配置虚拟接口模板VT，本端PPPoE协议对对端设备的认证方式为CHAP \[ISP\]int Virtual-Template 1 //创建VT接口，编号可以自定义，这组设置为1 \[ISP-Virtual-Template1\]ppp authentication-mode chap \[ISP-Virtual-Template1\]remote address pool pppoe //为PPPoE Clent指定IP地址池 \[ISP-Virtual-Template1\]ip add 20.20.20.1 24 \[ISP-Virtual-Template1\]qu 5、启用PPPoEServer功能。在以太网接口G0/0/0上启用PPPoE功能 \[ISP\]int g0/0/0 \[ISP-GigabitEthernet0/0/0\]pppoe-server bind virtual-template 1 //将G0/0/0和VT接口绑定 \[ISP-GigabitEthernet0/0/0\]qu \[ISP
二、配置PPPoEClient
1、RA的基本配置
<Huawei>sys
Enter system view, return user view with Ctrl+Z.
Huawei\]undo info-center ena Info: Information center is disabled. \[Huawei\]sysn RA \[RA\]int g0/0/1 \[RA-GigabitEthernet0/0/1\]ip add 192.168.10.254 24 \[RA-GigabitEthernet0/0/1\]qu 2、配置Dialer接口 \[RA\]int Dialer 0 \[RA-Dialer0\]link-protocol ppp \[RA-Dialer0\]ppp chap user admin \[RA-Dialer0\]ppp chap password cipher 123456 \[RA-Dialer0\]ip add ppp-negotiate \[RA-Dialer0\]tcp adjust-mss 1200 //最大报文长度 \[RA-Dialer0\]ip address ppp-negotiate //允许接口进行地址协商 \[\[RA-Dialer0\]dialer user admin //指定Dialer接口拨号使用的用户名 RA-Dialer0\]dialer bundle 1 //指定Dialer接口的编号 \[RA-Dialer0\]dialer timer idle 300 INFO: The configuration will become effective after link reset. \[RA-Dialer0\]dialer-group 1 //将该接口置于一个拨号组，并进行编号 \[RA-Dialer0\]qu 3、配置拨号规则dialer-rule \[RA\]dialer-rule \[RA-dialer-rule\]dialer-rule 1 ip permit \[RA-dialer-rule\]qu 4、建立PPPoE会话 \[RA\]int g0/0/0 \[RA-GigabitEthernet0/0/0\]pppoe-client dial-bundle-number 1 //将G0/0/0与VT1绑定 \[RA-GigabitEthernet0/0/0\]qu 5、配置NAT转换，配置局域用户通过NAT转换将私网地址转换为公网地址，并配置进行拨号上网的基本访问控制列表 \[RA\]acl number 3000 \[RA-acl-adv-3000\]rule 5 permit ip source 192.168.10.0 0.0.0.255 \[RA-acl-adv-3000\]qu \[RA\]int Dialer 0 \[RA-Dialer0\]nat outbound 3000 \[RA-Dialer0\]qu 6、配置到PPPoE Server的静态路由 RA\]ip route-static 0.0.0.0 0 Dialer 0 三、任务验收 1、在ISP上查看PPPoE会话信息  2、在RA上查看PPPoE会话信息  3、测试计算机的互通性
