PPPoE配置

1. 实验需求

1. 配置IP地址
2. 使用PPPOE拨号上网
3. 设置路由让直播业务部和营销部都可以访问外网

1. 实验拓扑

1. 实验步骤

1. 配置 R1地址池

1. 电信链路：

[Huawei]undo info-center  enable

Info: Information center is disabled.

[Huawei]sysname r1

[r1]ip pool zhibo　　//配置地址池名为zhibo

Info: It's successful to create an IP address pool.

[r1-ip-pool-zhibo]network 100.1.1.0 mask 24　　//客户端通过拨号所获取的网段地址

[r1-ip-pool-zhibo]gateway-list 100.1.1.1　　//配置分配的网关地址

[r1-ip-pool-zhibo]quit

1. 联通链路：

[r1]ip pool yingxiao　　//配置地址池名为yingxiao

Info: It's successful to create an IP address pool. 

[r1-ip-pool-yingxiao]network 200.1.1.0 mask 24　　//客户端通过拨号所获取的网段地址

[r1-ip-pool-yingxiao]gateway-list 200.1.1.1　       //配置分配的网关地址

[r1-ip-pool-yingxiao]quit

1. 配置R2、R3拨号使用的用户名和密码

[r1]aaa    

[r1-aaa]local-user zhibo password cipher zhibo　　//创建用户名为zhibo、密码为zhibo的账号

Info: Add a new user.

[r1-aaa]local-user zhibo service-type ppp　　//设置用户名为zhibo的服务类型为ppp

[r1-aaa]local-user yingxiao password cipher yingxiao　　//创建用户名为yingxiao、密码为yingxiao的账号

Info: Add a new user.

[r1-aaa]local-user yingxiao service-type ppp

[r1-aaa]quit

1. 配置VT接口，用于PPPoE认证并分配地址

[r1]interface Virtual-Template 1 　　//创建vt接口1

[r1-Virtual-Template1]ip address 100.1.1.1 24　　//将网关地址配置在VT接口

[r1-Virtual-Template1]ppp authentication-mode chap　　//配置ppp的认证类型为chap

[r1-Virtual-Template1]remote address pool zhibo　　//调用为客户端分配地址的地址池zhibo

[r1-Virtual-Template1]quit

[r1]interface Virtual-Template 2　　 //创建vt接口2

[r1-Virtual-Template2]ip address 200.1.1.1 24

[r1-Virtual-Template2]ppp authentication-mode chap

[r1-Virtual-Template2]remote address pool yingxiao

[r1-Virtual-Template2]quit

  

1. 在以太网接口使能PPPoE功能并绑定VT接口

[r1]interface g0/0/0

[r1-GigabitEthernet0/0/0]pppoe-server bind virtual-template 1　　//设置本设备为pppoe的服务端，并且关联VT接口

[r1-GigabitEthernet0/0/0]quit

[r1]interface g0/0/1

[r1-GigabitEthernet0/0/1]pppoe-server bind virtual-template 2

1. 配置R2、R3的PPPoE client拨号功能

 R2：

system-view

Enter system view, return user view with Ctrl+Z.

[Huawei]undo info-center enable

Info: Information center is disabled.

[Huawei]sysname r2

[r2]interface Dialer 0

[r2-Dialer0]dialer user user1

[r2-Dialer0]dialer bundle 1

[r2-Dialer0]ppp chap user zhibo

[r2-Dialer0]ppp chap password cipher zhibo

[r2-Dialer0]ip address ppp-negotiate

[r2-Dialer0]quit

R3：

system-view

Enter system view, return user view with Ctrl+Z.

[Huawei]undo info-center enable

Info: Information center is disabled.

[Huawei]sysname r2

[r3]interface Dialer 0

[r3-Dialer0]dialer user user1

[r3-Dialer0]dialer bundle 1

[r3-Dialer0]ppp chap user yingxiao       

[r3-Dialer0]ppp chap password cipher yingxiao

[r3-Dialer0]ip address ppp-negotiate

[r3-Dialer0]quit

1. 建立PPPoE会话

[r2]interface g0/0/0

[r2-GigabitEthernet0/0/0]pppoe-client dial-bundle-number 1   

[r2-GigabitEthernet0/0/0]quit

[r3]interface g0/0/0

[r3-GigabitEthernet0/0/0]pppoe-client dial-bundle-number 1   

[r3-GigabitEthernet0/0/0]quit

1. 查看客户端是否通过PPPoE获取IP地址

[r2]display ip interface brief

*down: administratively down

^down: standby

(l): loopback

(s): spoofing

The number of interface that is UP in Physical is 4

The number of interface that is DOWN in Physical is 1

The number of interface that is UP in Protocol is 2

The number of interface that is DOWN in Protocol is 3

Interface                         IP Address/Mask      Physical   Protocol 

Dialer0                           100.1.1.254/32       up         up(s)    

GigabitEthernet0/0/0              unassigned          up         down     

GigabitEthernet0/0/1              unassigned          up         down     

GigabitEthernet0/0/2              unassigned          down      down     

NULL0                          　unassigned          up         up(s)   

[r3]display ip interface brief

*down: administratively down

^down: standby

(l): loopback

(s): spoofing

The number of interface that is UP in Physical is 4

The number of interface that is DOWN in Physical is 1

The number of interface that is UP in Protocol is 2

The number of interface that is DOWN in Protocol is 3

Interface                         IP Address/Mask      Physical   Protocol 

Dialer0                           200.1.1.254/32       up         up(s)    

GigabitEthernet0/0/0              unassigned           up         down     

GigabitEthernet0/0/1              unassigned           up         down     

GigabitEthernet0/0/2              unassigned           down       down     

NULL0                             unassigned           up         up(s)     

可以看到都获取到了IP地址

1. 配置R2的G0/0/1和R3的G0/0/1的IP地址

[r2]interface g0/0/1        

[r2-GigabitEthernet0/0/1]ip address 192.168.1.254 24

[r2-GigabitEthernet0/0/1]quit

[r3]interface g0/0/1

[r3-GigabitEthernet0/0/1]ip address 192.168.2.254 24

[r3-GigabitEthernet0/0/1]quit

1. 配置主机IP地址

1. 配置NAT，让私网能去访问公网

[r2]acl 2000

[r2-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255

[r2-acl-basic-2000]quit

[r2]interface Dialer 0

[r2-Dialer0]nat outbound 2000

[r3]acl 2000

[r3-acl-basic-2000]rule permit source 192.168.2.0 0.0.0.255

[r3-acl-basic-2000]quit

[r3]interface Dialer 0

[r3-Dialer0]nat outbound 2000

[r3-Dialer0]quit

1. 配置静态路由

R2：

[r2]ip route-static 1.1.1.0 24 100.1.1.1

R3：

[r3]ip route-static 1.1.1.0 24 200.1.1.1
