【网络】配置VLANIF接口实现VLAN间的通信示例

组网需求：

配置S5700-28C-HI交换机的二层接口G0/0/1和G0/0/2分别与PC相连，PC1和PC2属于不同的网段。
通过配置不同的VLAN，将二层的广播报文限制在各VLAN内；通过配置VLANIF接口，VLAN间可以经VLANIF三层接口路由转发报文，实现VLAN间的通信。

配置步骤

1.S5700-28C-HI交换机的配置

system-view                                          #进入系统视图
[Huawei]sysname  S5700-28C-HI                                #配置交换机的名称为 S5700-28C-HI 
[S5700-28C-HI]vlan batch 10 20                               #批量创建 VALN 10 和 VLAN 20
[S5700-28C-HI]interface  Vlanif  10                          #进入VLANIF10接口
[S5700-28C-HI-Vlanif10]ip address 10.10.10.1 24              #配置IP地址为 10.10.10.1，掩码长度为24位
[S5700-28C-HI-Vlanif10]quit                                  #退出VLANIF10接口
[S5700-28C-HI]interface  Vlanif  20                          #进入VLANIF 20接口
[S5700-28C-HI-Vlanif20]ip address  10.10.20.1 24             #配置IP地址位 10.10.20.1，掩码长度为24位
[S5700-28C-HI-Vlanif20]quit                                  #退出VLANIF 20接口
[S5700-28C-HI]interface  GigabitEthernet  0/0/1              #进入千兆以太网接口 G 0/0/1
[S5700-28C-HI-GigabitEthernet0/0/1]port link-type access     #配置端口链路类型位ACCESS
[S5700-28C-HI-GigabitEthernet0/0/1]port default  vlan  10    #配置端口的默认VLAN为10
[S5700-28C-HI-GigabitEthernet0/0/1]quit                      #退出千兆接口 G0/0/1
[S5700-28C-HI]interface   GigabitEthernet 0/0/2              #进入千兆以太网接口 G0/0/2
[S5700-28C-HI-GigabitEthernet0/0/2]port link-type access     #配置端口的链路类型为 ACCESS
[S5700-28C-HI-GigabitEthernet0/0/2]port default vlan 20      #配置端口的默认VLAN 为20

验证配置

1.PC 1上ping 测试
分别ping ：
自己的网关 10.10.10.1 ，
对方的网段 10.10.20.1
对方的IP地址 10.10.20.2
