一、实验拓扑

二、实验划分

三、实验需求

四、实验结果

1.配置各端口和pc的IP：

pc1：

pc2：

pc3：

pc4：

R1:

[r1]inter g0/0/0
[r1-GigabitEthernet0/0/0]ip ad 192.168.1.2 24
[r1-GigabitEthernet0/0/0]int s4/0/0
[r1-Serial4/0/0]ip ad 15.1.1.1 24

R2:

[r2]inter g0/0/0
[r2-GigabitEthernet0/0/0]ip ad 192.168.2.2 24
[r2-GigabitEthernet0/0/0]int s4/0/0
[r2-Serial4/0/0]ip ad 25.1.1.2 24

R3:

[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip ad 192.168.3.2 24
[r3-GigabitEthernet0/0/0]int s4/0/0
[r3-Serial4/0/0]ip ad 35.1.1.3 24

R4:

[r4]int g0/0/1
[r4-GigabitEthernet0/0/1]ip ad 192.168.4.2 24
[r4-GigabitEthernet0/0/1]int g0/0/0

[r5-GigabitEthernet0/0/0]ip ad 45.1.1.5 24
[r5]int LoopBack 0
[r5-LoopBack0]ip ad 5.5.5.1 24

2.实现公私网通

公网通，配置静态缺省路由：

R1:

[r1]ip route-static 0.0.0.0 0 15.1.1.5

R2:

[r2]ip route-static 0.0.0.0 0 25.1.1.5

R3:

[r3]ip route-static 0.0.0.0 0 35.1.1.5

R4:

[r4]ip route-static 0.0.0.0 0 45.1.1.5

3.R1和R5之间使用ppp的PAP认证，R5为主认证方；R2和R5之间使用ppp的CHAP认证，R5为主认证方；R3和R5之间使用HDLC封装

R1和R5之间：

R5：

[r5]aaa
[r5-aaa]local-user jio1 password cipher jio1123
[r5-aaa]local-user jio1 service-type ppp
[r5]inter s4/0/1
[r5-Serial4/0/1]ppp authentication-mode pap

R1：

[r1-Serial4/0/0]ppp pap local-user jiojio password cipher 123456

R2和R5之间：

R5：

[r5]aaa
[r5-aaa]local-user duer password cipher 123456
[r5-aaa]local-user duer service-type ppp
[r5]int s3/0/1
[r5-Serial3/0/1]ppp authentication-mode chap

R2:

[r2-Serial4/0/0]ppp chap user duer
[r2-Serial4/0/0]ppp chap password cipher 123456

R3和R5之间使用HDLC封装：

R3:

[r3-Serial4/0/0]link-protocol hdlc 
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

R5:

[r5-Serial4/0/0]link-protocol hdlc 
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

4.R1~R3构建MGRE

R1:

[r1]int Tunnel 0/0/0
[r1-Tunnel0/0/0]ip address 10.1.2.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/0]source 15.1.1.1
[r1-Tunnel0/0/0]nhrp network-id 100

R2:

[r2]int Tunnel 0/0/0	
[r2-Tunnel0/0/0]ip ad 10.1.2.2 24
[r2-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r2-Tunnel0/0/0]source s4/0/0
[r2-Tunnel0/0/0]nhrp network-id 100
[r2-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

R3:

[r3]int Tunnel 0/0/0
[r3-Tunnel0/0/0]ip ad 10.1.2.3 24
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r3-Tunnel0/0/0]source s4/0/0
[r3-Tunnel0/0/0]nhrp network-id 100
[r3-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

5.R1到R4之间配置GRE VPN

R1:

[r1]int Tunnel 0/0/1
[r1-Tunnel0/0/1]ip ad 10.1.1.1 24
[r1-Tunnel0/0/1]tunnel-protocol gre
[r1-Tunnel0/0/1]source 15.1.1.1
[r1-Tunnel0/0/1]destination 45.1.1.4

R4:

[r4]int t0/0/1
[r4-Tunnel0/0/1]ip ad 10.1.1.4 24
