实验任务一：PPP协议基本配置
建立物理连接
- 接口配置Ppp协议

Serial1/0
Current state: UP
Line protocol state: UP
Description: Serial1/0 Interface
Bandwidth: 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

Last link flapping: 0 hours 4 minutes 51 seconds
Last clearing of counters: Never 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。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- RTA上配置本地验证对端RTB的方式PAP
[RTA-Serial1/0]ppp authentication-mode pap 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
Bandwidth: 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

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

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.
- 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 - 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
