交换机S5700

终端PC

一、单臂路由
实验拓扑

R1配置
为接口eth0/0/0配置IP可以不配置

[Huawei]int Eth 0/0/0
[Huawei-Ethernet0/0/0]ip add 1.1.1.1 24

为子接口eth0/0/0.1配置IP启用dot1q协议绑定vlan 10

[Huawei]int Eth 0/0/0.1
[Huawei-Ethernet0/0/0.1]ip add 192.168.1.254 24
[Huawei-Ethernet0/0/0.1]vlan-type dot1q 10或dot1q termination vid 10

如果不通开启子接口arp广播

[Huawei-Ethernet0/0/0.1]arp broadcast enable

为子接口eth0/0/0.2配置IP启用dot1q协议绑定vlan 20

[Huawei]int Eth 0/0/0.2
[Huawei-Ethernet0/0/0.2]ip add 192.168.2.254 24
[Huawei-Ethernet0/0/0.2]vlan-type dot1q 20或dot1q termination vid 20

如果不通开启子接口arp广播

[Huawei-Ethernet0/0/0.2]arp broadcast enable

SW配置
创建vlan 10和vlan 20

[Huawei]vlan 10
[Huawei-vlan10]vlan 20

将ge0/0/2和ge0/0/3配置为access模式加入vlan 10

[Huawei]int GigabitEthernet 0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 10
[Huawei]int GigabitEthernet 0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type access
[Huawei-GigabitEthernet0/0/3]port default vlan 10

将ge0/0/4配置为access模式加入vlan 20

[Huawei]int GigabitEthernet 0/0/4
[Huawei-GigabitEthernet0/0/4]port link-type access
[Huawei-GigabitEthernet0/0/4]port default vlan 20

将ge0/0/1设置为trunk模式允许所有vlan 10 20

[Huawei]int GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

PC配置
PC1

IP 192.168.1.1
NETMASK 255.255.255.0
GATEWAY 192.168.1.254

PC2

IP 192.168.1.2
NETMASK 255.255.255.0
GATEWAY 192.168.1.254

PC3

IP 192.168.2.1
NETMASK 255.255.255.0
GATEWAY 192.168.2.254

测试
192.168.1.1 ping 192.168.2.1

二、三层访问
实验拓扑

SW配置
创建vlan 10 20

[Huawei]vlan 10
[Huawei-vlan10]vlan 20
[Huawei-vlan10]q

给vlan配置IP

[Huawei]int vlan 10
[Huawei-Vlanif10]ip add 192.168.1.254 24
[Huawei-Vlanif10]q
[Huawei]int vlan 20
[Huawei-Vlanif20]ip add 192.168.2.254 24
[Huawei-Vlanif20]q

将ge0/0/1和ge0/0/2加入vlan 10

[Huawei]int GigabitEthernet 0/0/1
Huawei-GigabitEthernet0/0/1]port link-type access
[Huawei-GigabitEthernet0/0/1]port default vlan 10
[Huawei-GigabitEthernet0/0/1]q
[Huawei]int GigabitEthernet 0/0/2
Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 10

将ge0/0/3加入vlan 20

[Huawei]int GigabitEthernet 0/0/3
Huawei-GigabitEthernet0/0/3]port link-type access
[Huawei-GigabitEthernet0/0/3]port default vlan 20
