1. 如何配置单臂路由

    

   一、配置基本拓扑结构

   一台主路由器、二台交换机、二台测试路由器，测试路由器充当电脑使用

   
2.  

   二、配置接口IP地址

   R1的接口：[R1-GigabitEthernet0/0/1] ip address 10.0.2.2 255.255.255.0 

   R2的接口：[R2-GigabitEthernet0/0/2]ip address 10.0.3.2 255.255.255.0

   R3的接口：interface GigabitEthernet0/0/1

                                ip address 10.0.2.1 255.255.255.0 

                    interface GigabitEthernet0/0/2

                                ip address 10.0.3.1 255.255.255.0 

   

   
3.  

   三、关闭S2的G0/0/4接口并S1、S2的G0/0/09接口加入VLAN3

   [S2]interface GigabitEthernet 0/0/4 

   [S2-GigabitEthernet0/0/4]shutdown 

   [S2]interface GigabitEthernet 0/0/9 

   [S2-GigabitEthernet0/0/9]port link-type access 

   [S2-GigabitEthernet0/0/9]port default vlan 3 

   [S1]interface GigabitEthernet 0/0/9 

   [S1-GigabitEthernet0/0/9]port link-type access 

   [S1-GigabitEthernet0/0/9]port default vlan 3 

   
4.  

   四、将S1的G0/0/4接口改成TRUNK模式，允许通过VLAN2、VLAN3

   [S1]interface GigabitEthernet 0/0/4 

   [S1-GigabitEthernet0/0/4]port default vlan 1 

   [S1-GigabitEthernet0/0/4]port link-type trunk 

   [S1-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 3 

   

   
5.  

   五、在R3上的G0/0/1接口上配置子接口，同时在子接口配置ip地址，把接口配置成Dot1q,终结以太网接子接口

   [R4]inter GigabitEthernet 0/0/1.2 

   [R4-GigabitEthernet0/0/1.2]control-vid 20 dot1q-termination 

   [R4-GigabitEthernet0/0/1.2]dot1q termination vid 2 

   [R4-GigabitEthernet0/0/1.2]arp broadcast enable 

   [R4-GigabitEthernet0/0/1.2]ip address 10.0.20.1 24 

   [R4-GigabitEthernet0/0/1.2]inter GigabitEthernet 0/0/1.3 

   [R4-GigabitEthernet0/0/1.3]control-vid 30 dot1q-termination 

   [R4-GigabitEthernet0/0/1.3]dot1q termination vid 3 

   [R4-GigabitEthernet0/0/1.3]arp broadcast enable 

   [R4-GigabitEthernet0/0/1.3]ip address 10.0.30.1 24

   

   
6.  

   六、更改R1、R2的IP地址和网关

   [R1]inter GigabitEthernet 0/0/1 

   [R1-GigabitEthernet0/0/1]ip address 10.0.20.2 24 

   [R1-GigabitEthernet0/0/1]quit 

   [R1]undo ip route-static 0.0.0.0 0 10.0.2.1 

   [R1]ip route-static 0.0.0.0 0 10.0.20.1 

   [R2]interface GigabitEthernet 0/0/2 

   [R2-GigabitEthernet0/0/2]ip address 10.0.30.2 24 

   [R2-GigabitEthernet0/0/2]quit 

   [R2]undo ip route-static 0.0.0.0 0 10.0.3.1 

   [R2]ip route-static 0.0.0.0 0 10.0.30.1

   

   
7.  

   七、验证实验结果

   [R1]ping -c 1 10.0.30.2 

   PING 10.0.30.2: 56 data bytes, press CTRL_C to break 

   Reply from 10.0.30.2: bytes=56 Sequence=1 ttl=254 time=3 ms 

   --- 10.0.30.2 ping statistics --- 

   1 packet(s) transmitted 

   1 packet(s) received 

   0.00% packet loss 

   round-trip min/avg/max = 3/3/3 ms
