一.配置vlan、 

1.配置H3C1的vlan，及vlan查看命令??！

  [H3C1]display vlan

  [H3C1]display vlan all

  [H3C1]display port trunk

  [H3C1]display interface e0/4/3

2.配置H3C2的vlan

3,解決默認只允許vlan1通過trunk鏈路

[H3C1-Ethernet0/4/3]port trunk permit vlan all

vlan間路由

1.三層交換trunk和hybrid

2.單臂路由

一.配置vlan、trunk

1.配置H3C1

[H3C1]int vlan 1                 //為vlan1配置ip地址

[H3C1-Vlan-interface1]ip add 1.1.1.1 255.255.255.0

[H3C1-Vlan-interface1]un shut

[H3C1]vlan 2                   //創(chuàng)建vlan2

[H3C1-vlan2]q   

[H3C1]int vlan 2                //為vlan2配置ip地址

[H3C1-Vlan-interface2]ip add 2.2.2.2 255.255.255.0

[H3C1-Vlan-interface2]un shut

[H3C1-Vlan-interface2]q

[H3C1]int e0/4/3               //開啟trunk鏈路

[H3C1-Ethernet0/4/3]port link-type trunk

交換機的配置：

[SW1]vlan 10

[SW1-vlan10]vlan 20　　創(chuàng)建vlan 10和vlan 20

[SW1-GigabitEthernet1/0/2]port link-type access

[SW1-GigabitEthernet1/0/2]port access vlan 10　　端口配置到vlan 10

[SW1]int gi 1/0/3

SW1-GigabitEthernet1/0/3]port link-type access

[SW1-GigabitEthernet1/0/3]port access vlan 20　　端口配置到vlan 20

接入路由的端口配置：trunk

[SW1]int gi 1/0/1

[SW1-GigabitEthernet1/0/1]port link-type trunk

[SW1-GigabitEthernet1/0/1]port trunk permit vlan 10 20　　端口模式為trunk，配置到vlan 10和vlan 20

路由器的配置：

與交換機相接的端口需要配置子端口

[R1]int gi 0/0

R1-GigabitEthernet0/0]undo shutdown　　確認端口開啟

[R1]int gi 0/0.10　　進入子端口

[R1-GigabitEthernet0/0.10]ip add 192.168.10.1 24　　配置端口ip

[R1-GigabitEthernet0/0.10]vlan-type dot1q vid 10　　配置該子端口為vlan 10服務

R1-GigabitEthernet0/0.10]dis this

nterface GigabitEthernet0/0.10

p address 192.168.10.1 255.255.255.0

lan-type dot1q vid 10

[R1]int gi 0/0.20

[R1-GigabitEthernet0/0.20]ip add 192.168.20.1 24

[R1-GigabitEthernet0/0.20]vlan-type dot1q vid 20

[R1-GigabitEthernet0/0.20]dis this

interface GigabitEthernet0/0.20

ip address 192.168.20.1 255.255.255.0

vlan-type dot1q vid 20

#

以上

配置完以后pc1和pc2可以跨vlan通信

pc1配置

ip 192.168.10.2/24

路由 ip routing-table 0.0.0.0 0 192.168.10.1

pc2配置

ip 192.168.20.2/24

路由 ip routing-table 0.0.0.0 0 192.168.20.1

實際上三層交換機有路由功能：可以在交換機上直接配置

int vlan 10 　　創(chuàng)建虛擬接口并未接口配置ip

　　ip add 192.168.10.1 24

int vlan 20 

　　ip add 192.168.20.1 24
