MultiLink PPP也叫MP原理和配置
了解MP的作用
增加设备之间的互联带宽
增加设备之间的链路可靠性
提高数据转发的效率
实现方式有：虚拟接口模板方式 MP-group 方式
mp的工作过程
mp链路协商与建立
1.dead阶段，与ppp相同
2.Established 阶段，需要额外协商工作方式，是sp还是mp
3.Authentication 阶段，认证只能配置在“物理接口”上
4.Network 阶段，进行ipcp的协商，确定ip地址参数
5.Terminate 阶段，与ppp相同
案例
如图配置接口IP地址
为了增加R1和R2之间的互联带宽，进行MP绑定
R1和R2之间采用CHAP双向认证，确保通信安全
用户名为Huawei，密码为 HCIE
配置思路：
1.配置终端设备
2.配置网络设备
-R1 认证端@设置mp-group，并且设置ip地址
br/>@设置mp-group，并且设置ip地址
@两个接口加入mp-group组@aaa认证设置本地用户和密码，设置服务类型ppp
br/>@aaa认证设置本地用户和密码，设置服务类型ppp
@两个接口上配置ppp的chap认证模式
-R2 被认证端@设置mp-group，并且设置ip地址
br/>@设置mp-group，并且设置ip地址
@两个接口加入mp-group组
@两个接口配置chap用户名 用户密码
双向认证就是反过来
-R1 被认证端 设置两个接口ppp chap用户和密码
-R2 认证端 aaa认证设置用户和密码 并且两个接口启用chap认证服务
3.验证与测试

5.1 问题
如图配置接口IP地址
为了增加R1和R2之间的互联带宽，进行MP绑定
R1和R2之间采用CHAP双向认证，确保通信安全
用户名为Huawei，密码为 HCIE
5.2 方案
搭建实验环境，如图-5所示。
图-5
5.3 步骤
实现此案例需要按照如下步骤进行。
1）配置内网设备 – 终端
PC1：
192.168.1.1
255.255.255.0
192.168.1.254
PC2：
192.168.2.2
255.255.255.0
192.168.2.254
2）配置R1 PPP 链路捆绑
<Huawei>undo terminal monitor
<Huawei>system-view
[Huawei]sysname R1
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.254 24
[R1-GigabitEthernet0/0/0]quit
[R1]interface Mp-group 0/0/12
[R1-Mp-group0/0/12]ip add 192.168.12.1 24
[R1-Mp-group0/0/12]quit

[R1-Serial4/0/0]quit
[R1]interface Serial 4/0/1
[R1-Serial4/0/1]ppp chap user Huawei
[R1-Serial4/0/1]ppp chap password cipher HCIE
[R1-Serial4/0/1]quit
6）配置静态路由
[R1]ip route-static 192.168.2.0 24 192.168.12.2
[R2]ip route-static 192.168.1.0 24 192.168.12.1
