华为eNSP配置VLAN间通信实验（三层交换）

1、一、配置基本的拓扑结构

由于配置三层交换通信，R3属于上次实验遗留下的，在本次实验中关闭相应的接口，S1、S2是本次实验配置重点

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S1的G0/0/4接口，并验证网络现在状况

[S1]interface GigabitEthernet 0/0/4 

[S1-GigabitEthernet0/0/4]shutdown 

[R1]ping 10.0.30.2

  PING 10.0.30.2: 56  data bytes, press CTRL_C to break

    Request time out

    Request time out

    Request time out

    Request time out

    Request time out

  --- 10.0.30.2 ping statistics ---

    5 packet(s) transmitted

    0 packet(s) received

    100.00% packet loss

4、四、更改S1、S2的G0/0/9端口模式为TRUNK，并运行通过VLAN2、VLAN3

[S1]interface GigabitEthernet 0/0/9 

[S1-GigabitEthernet0/0/9]port default vlan 1 

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

[S1-GigabitEthernet0/0/9]port trunk allow-pass vlan 2 3 

[S2]interface GigabitEthernet 0/0/9 

[S2-GigabitEthernet0/0/9]port default vlan 1 

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

[S2-GigabitEthernet0/0/9]port trunk allow-pass vlan 2  3

5、五、在S1上创建VLANif2、VLANif3

[S1]interface Vlanif 2 

[S1-Vlanif2]ip address 10.0.20.1 24 

[S1]inter Vlanif 3 

[S1-Vlanif3]ip address 10.0.30.1 24

6、六、测试网络的联通性

[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=2 ms 

--- 10.0.30.2 ping statistics --- 

1 packet(s) transmitted 

1 packet(s) received 

0.00% packet loss 

round-trip min/avg/max = 2/2/2 ms
