H3C设备之 PPP PAP认证
PPP PAP认证：
路由器使用广域网封装协议：PPP<H3C路由器默认广域网接口封装方式>：
[RTA]int e0/0
[RTA-Ethernet0/0]ip add 192.168.1.1 24
[RTA]int s0/0
[RTA-s0/0]ip add 10.1.1.1 24
[RTB]int e0/0
[RTB-Ethernet0/0]ip add 192.168.2.1 24
[RTB]int s0/0
[RTB-s0/0]ip add 10.1.1.2 24

[RTA]ip route-static 192.168.2.0 255.255.255.0 10.1.1.2
[RTB]ip route-static 192.168.1.0 255.255.255.0 10.1.1.1
RTA]int s0/0
[RTA-s0/0]link-protocol ppp
[RTA-s0/0]buadrate 9600
[RTB]int s0/0
[RTB-s0/0]link-protocol ppp
[RTA]disp int s0/0/0
Serial0/0/0 current state: UP
Line protocol current state: UP
Description: Serial0/0/0 Interface
The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
Internet Address is 10.1.1.1/24 Primary
Link layer protocol is PPP
LCP opened, IPCP opened
Output queue : (Urgent queuing : Size/Length/Discards) 0/50/0
Output queue : (Protocol queuing : Size/Length/Discards) 0/500/0
Output queue : (FIFO queuing : Size/Length/Discards) 0/75/0
Interface is V35
608 packets input, 10308 bytes
597 packets output, 10454 bytes
配置PAP认证方式，主验证方为RTA：
[RTA]local-user pap
[RTA-luser-pap]password simple pap12345678
[RTA-luser-pap]service-type ppp
[RTA]int s0/0/0
[RTA-Serial0/0/0]link-protocol ppp
[RTA-Serial0/0/0]ppp authentication-mode pap
此时RTA无法访问RTB因为RTB没有被验证：
[RTA-Serial0/0/0]ping 10.1.1.2
PING 10.1.1.3: 56 data bytes, press CTRL_C to break

--- 10.1.1.3 ping statistics ---
5 packet(s) transmitted
0 packet(s) received
100.00% packet loss
配置被验证方RTB：
[RTB]int s0/0/0
[RTB-Serial0/0/0]ppp pap local-user pap password simple pap12345678
[RTB-Serial0/0/0]link-protocol ppp
此时RTA ,RTB又可以互访了：
[RTB]ping 10.1.1.1
PING 10.1.1.1: 56 data bytes, press CTRL_C to break
