实验16配置PPP

实验任务一：PPP协议基本配置

1. 建立物理连接
   

2. 接口配置Ppp协议
   [RTA-Serial1/0]link-protocol ppp
   [RTB-Serial1/0]link-protocol ppp
   [RTA-Serial1/0]baudrate 2048000
   [RTA-Serial1/0]display interface Serial 1/0
   Serial1/0
   Current state: UP
   Line protocol state: UP
   Description: Serial1/0 Interface
   Band 64 kbps
   Maximum transmission unit: 1500
   Hold timer: 10 seconds, retry times: 5
   Internet address: 10.1.1.1/30 (primary)
   Link layer protocol: PPP
   LCP: opened, IPCP: opened
   Output queue - Urgent queuing: Size/Length/Discards 0/100/0
   Output queue - Protocol queuing: Size/Length/Discards 0/500/0
   Output queue - FIFO queuing: Size/Length/Discards 0/75/0
   Last link flapping: 0 hours 4 minutes 51 seconds
   Last clearing of counters: Never

3. 在RTA和RTB设置静态路由即可互通。
   实验任务二：PPP PAP认证配置
   PAP验证：
   （1）被验证方以明文发送用户名和密码到主验证方。
   （2）主验证方核实用户名和密码。如果此用户合法且密码正确，则会给对端发送ACK消息，通告对端验证通过，允许进入下一阶段协商；如果用户名不正确，则发送NAK消息，通告对端验证失败。

4. RTA配置本地用户名和密码
   [RTA]local-user rtb class network
   New local user added.
   [RTA-luser-network-rtb]service-type ppp
   [RTA-luser-network-rtb]password simple 123

5. RTA上配置本地验证对端RTB的方式PAP
   [RTA-Serial1/0]ppp authentication-mode pap

6. 配置完认证后复位接口
   [RTA-Serial1/0]shutdown
   [RTA-Serial1/0]undo shutdown
   4.查看接口状态
   [H3C-Serial1/0]display interface Serial 1/0
   Serial1/0
   Current state: UP
   Line protocol state: DOWN
   Description: Serial1/0 Interface
   Band 64 kbps
   Maximum transmission unit: 1500
   Hold timer: 10 seconds, retry times: 5
   Internet address: 10.1.1.1/30 (primary)
   Link layer protocol: PPP
   LCP: closed
   Output queue - Urgent queuing: Size/Length/Discards 0/100/0
   Output queue - Protocol queuing: Size/Length/Discards 0/500/0
   Output queue - FIFO queuing: Size/Length/Discards 0/75/0
   Last link flapping: 0 hours 0 minutes 7 seconds
   Last clearing of counters: Never

发现PCA ping不通PCB
5.在RTB配置PAP配置发送的用户名和密码
[RTB-Serial1/0]ppp pap local-user rtb password simple 123

[RTA-Serial1/0]display interface Serial 1/0
Serial1/0
Current state: UP
Line protocol state: UP
Description: Serial1/0 Interface
Band 64 kbps
Maximum transmission unit: 1500
Hold timer: 10 seconds, retry times: 5
Internet address: 10.1.1.1/30 (primary)
Link layer protocol: PPP
LCP: opened, IPCP: opened
Output queue - Urgent queuing: Size/Length/Discards 0/100/0
Output queue - Protocol queuing: Size/Length/Discards 0/500/0
Output queue - FIFO queuing: Size/Length/Discards 0/75/0
Last link flapping: 0 hours 1 minutes 53 seconds
Last clearing of counters: Never
发现PCA 能ping通PCB
实验任务三：PPP chap认证配置
CHAP验证：
1：主验证方主动发起验证请求，向被验证方发送一个随机数值，并同时将本端的用户名一起发送给被验证方。
2：被验证方收到主验证方的验证请求之后，检查本地密码。
3：主验证方用MD5算法对报文ID，本地保存的被验证方密码和原随机数生成的一个摘要，并于收到的摘要值进行比较。如果相同，则向被验证方发送A从knowledge消息声明验证通过；如果不通过，则发送Not Acknowledge.

1. RTA配置本地用户名和密码
   [RTA]local-user rtb class network
   New local user added.
   [RTA-luser-network-rtb]service-type ppp
   [RTA-luser-network-rtb]password simple 123
   2.RTA上配置本地验证对端RTB的方式chap
   [RTA-Serial1/0]ppp authentication-mode chap
2. 配置完认证后复位接口
   [RTA-Serial1/0]shutdown
   [RTA-Serial1/0]undo shutdown
   4.显示接口状态
   [RTA-Serial1/0]display interface Serial 1/0
   Serial1/0
   Current state: UP
   Line protocol state: DOWN
   Description: Serial1/0 Interface
   Band 64 kbps
   Maximum transmission unit: 1500
   Hold timer: 10 seconds, retry times: 5

   Last clearing of counters: Never
   5.在RTB配置验证方式chap
   [RTB-Serial1/0]ppp chap user rtb
   [RTB-Serial1/0]ppp chap password simple 123
   实验任务四：PPP MP配置
   1.配置Mp-group接口，配置ip地址
   [RTA]interface MP-group 1
   [RTA-MP-group1]ip address 10..1.1.1 30
   [RTA-Serial1/0]ppp mp MP-group 1

[RTB]interface MP-group 1
[RTB-MP-group1]ip address 10.1.1.2 30
[RTB-Serial1/0]ppp mp MP-group 1
2.验证查看MP效果
