拓扑图：

配置如下： R1：

Router>en Router#conf t

Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R1

R1(config)#username R2 password ccna R1(config)#int s1/0

R1(config-if)#ip add 192.168.1.2 255.255.255.0 R1(config-if)#encapsulation ppp

R1(config-if)#ppp authentication chap R1(config-if)#no shut

%LINK-5-CHANGED: Interface Serial1/0, changed state to down R1(config-if)# R2：

Router>en Router#conf t

Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname R2

R2(config)#username R1 password ccna R2(config)#int s1/0

R2(config-if)#ip add 192.168.1.3 255.255.255.0 R2(config-if)#encapsulation ppp

R2(config-if)#ppp authentication chap R2(config-if)#no shut

R2(config-if)#

%LINK-5-CHANGED: Interface Serial1/0, changed state to up

R2(config-if)#

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up
