实验目的

1、理解PAP认证的原理

2、掌握PAP认证的配置

实验拓扑

实验需求

1、根据实验拓扑图,完成设备的基本配置;

2、在R1和R2之间做PAP单向认证,R1是认证方,R2是被认证方。

实验步骤

步骤1:设备的基本配置

配置R1:

Router>enable

Router#configure terminal

Router(config)#hostname R1

R1(config)#no ip domain-lookup

R1(config)#line console 0

R1(config-line)#exec-timeout 0 0

R1(config-line)#logging synchronous

R1(config-line)#exit

R1(config)#interface serial1/0

R1(config-if)#ip address 12.1.1.1 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#end

R1#

配置R2:

Router>enable

Router#configure terminal

Router(config)#hostname R2

R2(config)#no ip domain-lookup

R2(config)#line console 0

R2(config-line)#exec-timeout 0 0

R2(config-line)#logging synchronous

R2(config-line)#exit

R2(config)#interface serial1/0

R2(config-if)#ip address 12.1.1.2 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#end

R2#

步骤2:配置PAP认证

配置R1

R1(config)#interface serial 1/0

R1(config-if)#encapsulation ppp //封装PPP

R1(config-if)#ppp authentication pap //启用PAP认证

R1(config-if)#exit

R1(config)#username xmws password wisdom //创建用户名和密码

R1(config)#end

R1#

配置R2

R2(config)#interface serial 1/0

R2(config-if)#encapsulation ppp //封装PPP

R2(config-if)#ppp pap sent-username xmws password wisdom //PAP发送的用户名和密码

R2(config-if)#end

R2#

步骤3:检查PAP认证

检查R1:

R1#show ip interface brief

Interface IP-Address OK? Method Status Protocol

Ethernet0/0 unassigned YES unset administratively down down

Ethernet0/1 unassigned YES unset administratively down down

Ethernet0/2 unassigned YES unset administratively down down

Ethernet0/3 unassigned YES unset administratively down down

Serial1/0 12.1.1.1 YES manual up up

Serial1/1 unassigned YES unset administratively down down

Serial1/2 unassigned YES unset administratively down down

Serial1/3 unassigned YES unset administratively down down

检查R2

R2#show ip interface brief

Interface IP-Address OK? Method Status Protocol

Ethernet0/0 unassigned YES unset administratively down down

Ethernet0/1 unassigned YES unset administratively down down

Ethernet0/2 unassigned YES unset administratively down down

Ethernet0/3 unassigned YES unset administratively down down

Serial1/0 12.1.1.2 YES manual up up

Serial1/1 unassigned YES unset administratively down down

Serial1/2 unassigned YES unset administratively down down

Serial1/3 unassigned YES unset administratively down down
