交换机基础配置之三层交换机实现vlan间通信

我们以上面的拓扑图做实验，要求为pc1，pc2，pc3配置为vlan10，pc4，pc5，pc6配置为vlan20，pc7，pc8，pc9配置为vlan30

server0和server1配置为vlan40，给各自vlan设置网关，实现三层交换机的跨交换机vlan通信，为求方便，我们先用到vtp，设置vtp域为qqq

首先给各个pc机和服务器设置好IP地址

先配置三层交换机switch1

enable　　进入特权模式

configure terminal　　进入全局配置模式

vtp domain qqq　　设置域名

vtp mode server　　设置为server

interface f0/1

switchport mode dynamic desirable

exit

vlan 10　　创建好vlan

vlan 20

vlan 30

vlan 40

给vlan配置网关

interface vlan 10

ip address 192.168.1.254 255.255.255.0

exit

interface vlan 20

ip address 192.168.2.254 255.255.255.0

exit

interface vlan 30

ip address 192.168.3.254 255.255.255.0

exit

interface vlan 40

ip address 192.168.4.254 255.255.255.0

配置switch2

enable

configure terminal

vtp domain qqq

vtp mode client

interface f0/2

switchport mode access

switchport access vlan 30

exit

nterface f0/3

switchport mode access

switchport access vlan 20

exit

nterface f0/4

switchport mode access

switchport access vlan 10

exit

interface f0/2（设置server0的vlan）

switchport mode access

switchport access vlan 40

interface f0/3

switchport mode access

switchport access vlan 40

在配置switch3

enable

configure terminal

vtp domain qqq

vtp mode client

interface f0/2

switchport mode trunk

exit

interface f0/3

switchport mode trunk

exit

interface f0/4

switchport mode access

switchport access vlan 30

exit

nterface f0/5

switchport mode access

switchport access vlan 20

exit

nterface f0/6

switchport mode access

switchport access vlan 10

exit

配置switch4

enable

configure terminal

vtp domain qqq

vtp mode client

interface f0/2

switchport mode access

switchport access vlan 30

exit

nterface f0/3

switchport mode access

switchport access vlan 20

exit

nterface f0/4

switchport mode access

switchport access vlan 10

exit

现在vlan10的网关为192.168.1.254

成员为pc1，2，3

vlan20的网关为192.168.2.254

成员为4，5，6

vlan30的网关为192.168.3.254

成员为7，8，9

vlan40的网关为192.168.4.254

成员为server0，server1

现在就已经完成了三层交换机的vlan通信了
