三层vlan间的交换

1、创建vlan 

Switch7(config)#vlan 2

Switch7(config)#name guo

Switch7(config)#vlan 3

Switch7(config)#name shi

Switch8(config)#vlan 2

Switch8(config)#name guo

Switch8(config)#vlan 3

Switch8(config)#name shi 

2、将端口加入vlan 

Interface Fa0/1

Switch7(config-if)#switchport mode access

Switch7(config-if)#switchport access vlan 2

Interface Fa0/2

Switch7(config-if)#switchport access vlan 3

Switch8(config-if)#switchport mode access

Switch8(config-if)#switchport access vlan 2

Switch8(config-if)#switchport access vlan 3 

3、创建Trunk 

Switch7(config)#interface range fastEthernet 0/3-4

Switch7(config)#switchport mode trunk

Switch8(config)#interface range fastEthernet 0/3

Switch8(config)#switchport mode trunk 

4、配置VTP 

Switch7(config)#vtp domain wei

Switch7(config)#vtp mode server

Switch7(config)#vtp password 123

Switch8(config)#vtp domain wei

Switch8(config)#vtp mode client

Switch8(config)#vtp password 123

5、配置三层交换

MS2(config)#interface fastEthernet 0/2

MS2(config-if)#switchport

MS2(config-if)#switchport trunk encapsulation dot1q 

MS2(config-if)#exit

MS2(config)#interface vlan 2

MS2(config-if)#ip address 192.168.1.1 255.255.255.0

MS2(config-if)#no shut

MS2(config)#interface vlan 3

MS2(config-if)#ip address 192.168.2.1 255.255.255.0

MS2(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.0

MS2(config)#ip route 192.168.2.0 255.255.255.0 192.168.1.0
