ppp实验

拓扑

实验步骤

配置ip,ppp自动启动

[r1]int s4/0/0
[r1-Serial4/0/0]ip a 192.168.1.1 24

interface Serial4/0/0
 link-protocol ppp
 ip address 192.168.1.2 255.255.255.0 

配置ppp mp

R2

interface Mp-group0/0/0
 ip address 192.168.2.1 255.255.255.0 

interface Serial3/0/0
 link-protocol ppp
 ppp mp Mp-group 0/0/0

interface Serial4/0/1
 link-protocol ppp
 ppp mp Mp-group 0/0/0

R3

interface Mp-group0/0/0
 ip address 192.168.2.2 255.255.255.0 

interface Serial4/0/0
 link-protocol ppp
 ppp mp Mp-group 0/0/0

interface Serial4/0/1
 link-protocol ppp
 ppp mp Mp-group 0/0/0

配置R1,R2单向chap

R2主验证

[r2-aaa]local-user huawei password cipher 12345 privilege level 15
[r2-aaa]local-user huawei service-type ppp
[r2-aaa]int s4/0/0
[r2-Serial4/0/0]link-protocol ppp
[r2-Serial4/0/0]ppp authentication-mode chap

R1被验证

[r1-Serial4/0/0]ppp chap user huawei 
[r1-Serial4/0/0]ppp chap password cipher 12345 

R2,R3双向认证

R2主验证

[r2-aaa]local-user huawei password cipher 12345 privilege level 15
[r2-aaa]local-user huawei service-type ppp
[r2-Serial3/0/0]link-protocol ppp
[r2-Serial3/0/0]ppp authentication-mode chap 
[r2-Serial3/0/0]int s4/0/1
[r2-Serial4/0/1]link-protocol ppp
[r2-Serial4/0/1]ppp authentication-mode chap

R3被验证

[r3]int s4/0/1
[r3-Serial4/0/1]ppp chap user huawei
[r3-Serial4/0/1]ppp chap password cipher 12345
[r3-Serial4/0/1]int s4/0/0
[r3-Serial4/0/0]ppp chap user huawei
[r3-Serial4/0/0]ppp chap password cipher 12345
[r3-Serial4/0/0]

R3主验证

[r3-aaa]local-user huawei1 password cipher 12345 privilege level 15
[r3-aaa]local-user huawei1 service-type ppp
[r3]int s4/0/1	
[r3-Serial4/0/1]link-protocol ppp
[r3-Serial4/0/1]ppp authentication-mode chap
[r3-Serial4/0/1]int s4/0/0
[r3-Serial4/0/0]link-protocol ppp
[r3-Serial4/0/0]ppp authentication-mode chap
[r3-Serial4/0/0]

R2被验证

[r2-Serial3/0/0]ppp chap user huawei1
[r2-Serial3/0/0]ppp chap password cipher 12345
[r2-Serial3/0/0]int s4/0/1
[r2-Serial4/0/1]ppp chap user huawei1
[r2-Serial4/0/1]ppp chap password cipher 12345
[r2-Serial4/0/1]
