【HCIP】RIP环境下的MGRE VPN实验练习笔记-EW帮帮网

一、实验拓扑

二、实验要求

R5为ISP，只能进行IP地址配置，其所有地址均配为公有IP地址；
R1和R5间使用PPP的PAP认证，R5为主认证；
R2与R5之间使用ppp的CHAP认证，R5为主认证方；
R3与R5之间使用HDLC封装；
R1、R2、R3构建一个MGRE环境，R1为中心站点，R1、R4间为点到点的GRE；
整个私有网络基本RIP全网可达；
所有PC设置私有IP为源IP，可以访问R5环回。

三、实验步骤

1、配置IP地址

[R1]int s4/0/0
[R1-Serial4/0/0]ip add 15.1.1.1 24
[R1-Serial4/0/0]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.1.254 24

[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.2.254 24
[R2-GigabitEthernet0/0/0]int s4/0/0
[R2-Serial4/0/0]ip add 25.1.1.2 24

[R3]int s4/0/0
[R3-Serial4/0/0]ip add 35.1.1.3 24
[R3-Serial4/0/0]int g0/0/0
[R3-GigabitEthernet0/0/0]ip add 192.168.3.254 24

[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 45.1.1.4 24
[R4-GigabitEthernet0/0/0]int g0/0/1
[R4-GigabitEthernet0/0/1]ip add 192.168.4.254 24

[R5]int s2/0/0
[R5-Serial2/0/0]ip add 15.1.1.5 24
[R5-Serial2/0/0]int s2/0/1
[R5-Serial2/0/1]ip add 25.1.1.5 24
[R5-Serial2/0/1]int s3/0/0
[R5-Serial3/0/0]ip add 35.1.1.5 24
[R5-Serial3/0/0]int g0/0/0
[R5-GigabitEthernet0/0/0]ip add 45.1.1.5 24
[R5-GigabitEthernet0/0/0]int lo1
[R5-LoopBack1]ip add 5.5.5.5 24

2、配置公网通

[R1]ip route-static 0.0.0.0 0 15.1.1.5
[R2]ip route-static 0.0.0.0 0 25.1.1.5
[R3]ip route-static 0.0.0.0 0 35.1.1.5
[R4]ip route-static 0.0.0.0 0 45.1.1.5

测试公网：

3、R1和R5间使用PPP的PAP认证，R5为主认证；

[ISP]aaa
[ISP-aaa]local-user wangdaye password cipher 123456 privilege level 15
[ISP-aaa]local-user wangdaye service-type ppp
[ISP-aaa]quit
[ISP]int s2/0/0
[ISP-Serial2/0/0]ppp authentication-mode pap
[ISP-Serial2/0/0]quit

[R1]int s4/0/0
[R1-Serial4/0/0]ppp pap local-user wangdaye password cipher 123456
[R1-Serial4/0/0]shutdown
[R1-Serial4/0/0]undo shutdown

4、R2与R5之间使用ppp的CHAP认证，R5为主认证方；

[ISP]aaa
[ISP-aaa]local-user lidaye password cipher 123456 privilege level 15	
[ISP-aaa]local-user lidaye service-type ppp
[ISP-aaa]quit
[ISP]int s2/0/1
[ISP-Serial2/0/1]ppp authentication-mode chap
[ISP-Serial2/0/1]quit

[R2]int s4/0/0
[R2-Serial4/0/0]ppp chap user lidaye
[R2-Serial4/0/0]ppp chap password cipher 123456
[R2-Serial4/0/0]shutdown
[R2-Serial4/0/0]undo shutdown

5、R3与R5之间使用HDLC封装；

[R3]int s4/0/0	
[R3-Serial4/0/0]link-protocol hdlc 
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

[ISP]int s3/0/0
[ISP-Serial3/0/0]link-protocol hdlc 
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y

6、R1、R2、R3构建一个MGRE环境，R1为中心站点；

[R1]int t0/0/0
[R1-Tunnel0/0/0]ip add 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]int t0/0/0
[R2-Tunnel0/0/0]ip add 10.1.2.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R2-Tunnel0/0/0]source 25.1.1.2
[R2-Tunnel0/0/0]nhrp network-id 100
[R2-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

[R3]int t0/0/0
[R3-Tunnel0/0/0]ip add 10.1.2.3 24	
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R3-Tunnel0/0/0]source 35.1.1.3	
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register

7、R1、R4间为点到点的GRE

[R1]int t0/0/1
[R1-Tunnel0/0/1]ip add 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
[R1-Tunnel0/0/1]quit

[R4]int t0/0/1
[R4-Tunnel0/0/1]ip add 10.1.1.4 24
[R4-Tunnel0/0/1]tunnel-protocol gre 
[R4-Tunnel0/0/1]source 45.1.1.4
[R4-Tunnel0/0/1]destination 15.1.1.1
[R4-Tunnel0/0/1]quit

8、整个私有网络基本RIP全网可达；

[R1]rip
[R1-rip-1]v 2	
[R1-rip-1]undo summary 
[R1-rip-1]net 192.168.1.0
[R1-rip-1]net 10.0.0.0
[R1-rip-1]quit

注意##在中心上开启伪广播，目的：告诉分支站点，中心站点及其他分支站点的私网网段信息。
[R1]int t0/0/0	
[R1-Tunnel0/0/0]nhrp entry multicast dynamic 

注意##分支站点只获取到了总部网段信息，并没有像预想的那样获得完整网段信息，这跟RIP的水平分割机制有关
##需要关闭RIP的水平分割来获取完整网段信息
[R1-Tunnel0/0/0]undo rip split-horizon
[R1-Tunnel0/0/0]quit

[R2]rip 
[R2-rip-1]v 2
[R2-rip-1]undo summary 
[R2-rip-1]net 192.168.2.0
[R2-rip-1]net 10.0.0.0
[R2-rip-1]quit

[R2]int t0/0/0	
[R2-Tunnel0/0/0]undo rip split-horizon
[R2-Tunnel0/0/0]quit

[R3]rip 
[R3-rip-1]v 2	
[R3-rip-1]undo summary 
[R3-rip-1]network  192.168.3.0
[R3-rip-1]net 10.0.0.0
[R3-rip-1]quit

[R3]int t0/0/0	
[R3-Tunnel0/0/0]undo rip split-horizon
[R3-Tunnel0/0/0]quit

[R4]rip
[R4-rip-1]v 2	
[R4-rip-1]undo summary 
[R4-rip-1]net 192.168.4.0
[R4-rip-1]net 10.0.0.0
[R4-rip-1]quit

[R4]int t0/0/0
[R4-Tunnel0/0/0]undo rip split-horizon
[R4-Tunnel0/0/0]quit

测试1：查看分支站点的RIP路由表学习情况

测试2：全网可达

9、所有PC设置私有IP为源IP，可以访问R5环回。

[R1]acl 2000	
[R1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[R1-acl-basic-2000]quit
[R1]int s4/0/0
[R1-Serial4/0/0]nat outbound 2000
[R1-Serial4/0/0]q

[R2]acl 2000
[R2-acl-basic-2000]rule permit source 192.168.2.0 0.0.0.255
[R2-acl-basic-2000]q
[R2]int s4/0/0
[R2-Serial4/0/0]nat outbound 2000
[R2-Serial4/0/0]q

[R3]acl 2000	
[R3-acl-basic-2000]rule permit source 192.168.3.0 0.0.0.255
[R3-acl-basic-2000]q
[R3]int s4/0/0	
[R3-Serial4/0/0]nat outbound 2000
[R3-Serial4/0/0]q

[R4]acl 2000	
[R4-acl-basic-2000]rule permit source 192.168.4.0 0.0.0.255
[R4-acl-basic-2000]q
[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]nat outbound 2000
[R4-GigabitEthernet0/0/0]q

测试：ping通R5环回
