HCL配置(二)–VLAN间通信

一、任务

Vlan间通信：
VLAN10、20、30、40内的主机之间互ping成功

二、配置

(一)通过三层交换机使用SVI实现通信

拓扑图如下：

拓扑

主机IP：

  • PC1：　192.168.10.100/24
  • PC2：　192.168.20.100/24
  • PC3：　192.168.30.100/24
  • PC4：　192.168.40.100/24

VLANIP规划：

  • VLAN10：　192.168.10.1/24
  • VLAN20：　192.168.20.1/24
  • VLAN30：　192.168.30.1/24
  • VLAN40：　192.168.40.1/24

1、配置PC

配置好IP地址，掩码，网关（网关是VLAN的IP）

2、最上面的交换机S0

命名

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sys LWS0

创建四个vlan

[LWS0]vlan 10
[LWS0-vlan10]quit
[LWS0]vlan 20
[LWS0-vlan20]vlan 30
[LWS0-vlan30]vlan 40
[LWS0-vlan40]quit

给vlan分配IP

[LWS0]int vlan 10
[LWS0-Vlan-interface10]ip add 192.168.10.1 255.255.255.0
[LWS0-Vlan-interface10]quit
[LWS0]int vlan 20
[LWS0-Vlan-interface20]ip add 192.168.20.1 255.255.255.0
[LWS0-Vlan-interface20]int vlan 30
[LWS0-Vlan-interface30]ip add 192.168.30.1 255.255.255.0
[LWS0-Vlan-interface30]int vlan 40
[LWS0-Vlan-interface40]ip add 192.168.40.1 255.255.255.0
[LWS0-Vlan-interface40]quit

接口设为trunk并允许所有vlan通过

[LWS0]int g1/0/1
[LWS0-GigabitEthernet1/0/1]port link-type trunk
[LWS0-GigabitEthernet1/0/1]port trunk permit vlan all
[LWS0-GigabitEthernet1/0/1]no sh
[LWS0-GigabitEthernet1/0/1]int g1/0/2
[LWS0-GigabitEthernet1/0/2]no sh
[LWS0-GigabitEthernet1/0/2]port link-ty t
[LWS0-GigabitEthernet1/0/2]port t p vlan all

3、左边交换机S1

命名

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sys LWS1
创建vlan
[LWS1]vlan 10
[LWS1-vlan10]vlan 20
[LWS1-vlan20]quit

与交换机相连的接口设为trunk，允许所有vlan通过

[LWS1-GigabitEthernet1/0/1]no sh
[LWS1-GigabitEthernet1/0/1]port link-ty t
[LWS1-GigabitEthernet1/0/1]port t p vlan all
[LWS1-GigabitEthernet1/0/1]quit

下面两个接口设为access

[LWS1]int g1/0/2
[LWS1-GigabitEthernet1/0/2]port link-ty a
[LWS1-GigabitEthernet1/0/2]port a vlan 10
[LWS1-GigabitEthernet1/0/2]int g1/0/3
[LWS1-GigabitEthernet1/0/3]no sh
[LWS1-GigabitEthernet1/0/3]port link-ty a
[LWS1-GigabitEthernet1/0/3]port a vlan 20
[LWS1-GigabitEthernet1/0/3]quit

4、右边交换机S2

[LWS2]vlan 30
[LWS2-vlan30]vlan 40
[LWS2-vlan40]quit
[LWS2]int g1/0/1
[LWS2-GigabitEthernet1/0/1]port link-ty t
[LWS2-GigabitEthernet1/0/1]port t p vlan all
[LWS2-GigabitEthernet1/0/1]quit
[LWS2]int g1/0/2
[LWS2-GigabitEthernet1/0/2]port link-ty a
[LWS2-GigabitEthernet1/0/2]port a vlan 30
[LWS2-GigabitEthernet1/0/2]int g1/0/3
[LWS2-GigabitEthernet1/0/3]port link-ty a
[LWS2-GigabitEthernet1/0/3]port a vlan 40
[LWS2-GigabitEthernet1/0/3]quit

5、测试

(二)其他方法

其他的网上有详细的配置，因此只给出方法

1、如果只有两个VLAN，那么可以在交换机端口设置trunk的本征VLAN，自行去标签

多个VLAN的话设成Hybrid口，用untag撕去标签

2、通过路由接口

3、通过单臂路由
