RIP下MGRE综合实验

1、实验拓扑图：

2、实验要求：

        1、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；
        2、R1和R5间使用ppp的PAP认证，R5为主认证方；
        3、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；
        4、整个私有网络基本RIP全网可达；
        5、所有pc设置私有IP为源IP，可以访问R5环回，达到全网可达。

3、配置接口IP：

R1:

[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]ip address 192.168.1.3 24
[R1]interface Serial 4/0/0	
[R1-Serial4/0/0]ip address 15.1.1.1 24

[R1]display ip interface brief    # 查看接口IP是否配置成功

R2:

[R2]interface g0/0/0
[R2-GigabitEthernet0/0/0]ip address 192.168.2.3 24
[R2]interface Serial 4/0/0	
[R2-Serial4/0/0]ip address 25.1.1.1 24

R3:

[R3]interface g0/0/0
[R3-GigabitEthernet0/0/0]ip address 192.168.3.3 24
[R3]interface Serial 4/0/0	
[R3-Serial4/0/0]ip address 35.1.1.1 24

R4:

[R4]interface g0/0/1
[R4-GigabitEthernet0/0/1]ip address 192.168.4.3 24
[R4]interface g0/0/0	
[R4-GigabitEthernet0/0/0]ip address 45.1.1.2 24

R5:

[R5]interface LoopBack 0
[R5-LoopBack0]ip address 5.5.5.5 24

4、R1 R2 R3 R4缺省路由：

[R1]ip route-static 0.0.0.0 0 15.1.1.2
[R2]ip route-static 0.0.0.0 0 25.1.1.2
[R3]ip route-static 0.0.0.0 0 35.1.1.2
[R4]ip route-static 0.0.0.0 0 45.1.1.1

5、配置NAT进行地址转换：

R1:

[R1]acl 2000
[R1-acl-basic-2000]rul 1 permit source any
[R1-acl-basic-2000]quit
[R1]interface Serial 4/0/0
[R1-Serial4/0/0]nat outbound 2000

R2:

[R2]acl 2000
[R2-acl-basic-2000]rul 1 permit source any
[R2-acl-basic-2000]quit
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]nat outbound 2000

R3:

[R3]acl 2000
[R3-acl-basic-2000]rul 1 permit source any
[R3-acl-basic-2000]quit
[R3]interface Serial 4/0/0
[R3-Serial4/0/0]nat outbound 2000

R4:

[R4]acl 2000
[R4-acl-basic-2000]rul 1 permit source any
[R4-acl-basic-2000]quit
[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]nat outbound 2000

6、R1和R5间使用PPP的PAP认证，R5为主认证方：

主认证方R5：

[R5]aaa
[R5-aaa]local-user chen password cipher 123456
[R5-aaa]local-user chen service-type ppp
[R5-aaa]quit
[R5]interface Serial 4/0/1
[R5-Serial4/0/1]ppp authentication-mode pap

被认证方R1 ：

[R1]interface Serial 4/0/0
[R1-Serial4/0/0]ppp pap local-user chen password cipher 123456

7、R2于R5之间使用PPP的chap认证，R5为主认证方：

主认证方R5：

[R5]aaa
[R5-aaa]local-user chen password cipher 123456
[R5-aaa]local-user chen service-type ppp
[R5-aaa]quit
[R5]interface Serial 3/0/1
[R5-Serial3/0/1]ppp authentication-mode chap

被认证方R2：

[R2]interface Serial 4/0/0
[R2-Serial4/0/0]ppp chap user chen
[R2-Serial4/0/0]ppp chap password cipher 123456

8、R3于R5之间使用HSDLXC封装：
