vlan实验

 实验要求：

1，全网可达
2，pc通过DHCP获取地址

第一步，在交换机上创建 VLAN

配置命令

int g 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type access
[sw1-GigabitEthernet0/0/2]port default vlan 10
 

第二步，将接口划入 VLAN

[sw1]interface GigabitEthernet 0/0/1 // 进入接口

[sw1-GigabitEthernet0/0/1]port link-type access // 将接口类型更改为 access

[sw1-GigabitEthernet0/0/1]port default vlan 2 // 将接口划分给 vlan 2

[sw1]display vlan summary // 查看 vlan 简表

[sw1]display vlan // 查看 vlan 表

 

第三步，配置 Trunk 干道

配置位置，交换机与交换机相连的接口

配置命令

[sw1]interface GigabitEthernet 0/0/3

[sw1-GigabitEthernet0/0/3]port link-type trunk 

trunk

[sw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20

配置路由：

[r1]int g 0/0/0.1

[r1-GigabitEthernet0/0/0.1]ip address 192.168.10.126 25
 

[r1-GigabitEthernet0/0/0.1]dot1q termination vid 10

[r1-GigabitEthernet0/0/0.1]arp broadcast enable
 

[r1-GigabitEthernet0/0/0.1]dhcp select  global

[r1]int g 0/0/0.2

[r1-GigabitEthernet0/0/0.2]ip address 192.168.20.126 25   ^

[r1-GigabitEthernet0/0/0.2]dot1q termination vid 20

[r1-GigabitEthernet0/0/0.2]arp broadcast enable

[r1-GigabitEthernet0/0/0.2]dhcp select  global

[r1]int g 0/0/1.1
[r1-GigabitEthernet0/0/1.1]ip address 192.168.10.254 25

[r1-GigabitEthernet0/0/1.1]dot1q termination vid 10

[r1-GigabitEthernet0/0/1.1]arp broadcast enable

[r1-GigabitEthernet0/0/1.1]dhcp select  global

[r1]int g 0/0/1.2
[r1-GigabitEthernet0/0/1.2]ip address 192.168.20.254 25
[r1-GigabitEthernet0/0/1.2]dot1q termination vid 20
[r1-GigabitEthernet0/0/1.2]arp broadcast enable

[r1-GigabitEthernet0/0/1.2]dhcp select  global
