三层VLAN划分(华为eNSP)

发布时间:2024年01月18日

前言:通过三层交换技术构建vlan间路由,避免单臂路由配置繁杂,带宽承载力过小等问题,提高网络健壮性和可维护性。

1、topo图:

2、配置思路:

(1) PC配置?

????????PC1:192.168.1.10/24

????????PC2:192.168.2.20/24

????????PC3:192.168.2.21/24

????????PC4:192.168.3.30/24

(2)SW2:

??????? 1,创建vlan10、vlan20:

[SW2]vlan batch 10 20    //批量创建vlan10、vlan20

??????? 2,配置access类型接口,将eth0/0/1口划入vlan10:

???????ATTENTION:只能先配置接口类型,才能划入vlan)

[SW2]int e0/0/1    //进入0/0/1口
[SW2-Ethernet0/0/1]port link-type access   //配置接口类型access
[SW2-Ethernet0/0/1]port default vlan 10    //划分vlan10

??????? 3,将eth0/0/2口划入vlan20,配置access类型接口:

[SW2]int e0/0/2
[SW2-Ethernet0/0/2]port link-type access 
[SW2-Ethernet0/0/2]port default vlan 20

??????? 4,配置eth0/0/3为trunk:

[SW2-Ethernet0/0/3]port link-type trunk 

(3)SW3:同SW2

??????? 1,创建vlan20、vlan30:

[SW3]vlan batch 20 30

??????? 2, eth0/0/1口划入vlan20,配置access类型接口:

[SW3]int e0/0/1

[SW3-Ethernet0/0/1]port link-type access

[SW3-Ethernet0/0/1]port default vlan 20

??????? 3,eth0/0/2口划入vlan30,配置access类型接口:

[SW3]int Eth0/0/2

[SW3-Ethernet0/0/2]port link-type access

[SW3-Ethernet0/0/2]port default vlan 30

??????? 4, 配置eth0/0/3为trunk型接口:

[SW3]int Ethernet0/0/3

[SW3-Ethernet0/0/3]port link-type trunk

(4)SW6:

??????? 创建vlan10、vlan20、vlan30:

[SW6]vlan batch 10 20 30    //批量创建vlan10,vlan20,vlan30

????????配置eth0/0/1,eth0/0/2 为trunk接口,并允许全部vlan通信:

[SW6]int Eth0/0/1
[SW6-Ethernet0/0/1]port link-type trunk 
[SW6-Ethernet0/0/1]port trunk allow-pass vlan all      //允许通过所有vlan通过
[SW6]int Eth0/0/2
[SW6-Ethernet0/0/2]port link-type trunk 
[SW6-Ethernet0/0/2]port trunk allow-pass vlan all 

??????? 配置网关地址:

[SW6]int Vlanif 10
[SW6-Vlanif10]ip address 192.168.1.1 24

[SW6]interface  Vlanif 20
[SW6-Vlanif20]ip address 192.168.2.1 24

[SW6]int Vlanif 30
[SW6-Vlanif30]ip address 192.168.3.1 24

vlanif:虚拟vlan接口,用来指明对应vlan网关。

(5)预期效果:

??????? 不同vlan,不同网关之间可以ping通。

(6)验证:

方法:各个PC互ping
