计算机网路vlan划分练习

 配置如图的练习，要求：lsw1和lsw2内有两个网段，lsw3内有两个网段。全网可达

分析：

①lsw1和lsw2存在两个vlan（vlan2和vlan3），而lsw3也存在两个独立的vlan（vlan2和vlan3），所以要对交换机进行vlan划分

②交换机和交换机之间要能进行数通，并且可以全网可达，所以要配置干道

③需要配置dhcp池和接口划分

解：

第一步：交换机的vlan划分

//lsw1
sys
[Huawei]vlan batch 2 to 3
[Huawei]interface g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 2
[Huawei]interface g0/0/3
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 3//lsw2
sys
[Huawei]vlan batch 2 to 3
[Huawei]interface g0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type access
[Huawei-GigabitEthernet0/0/3]port default vlan 2
[Huawei]interface g0/0/4
[Huawei-GigabitEthernet0/0/4]port link-type access
[Huawei-GigabitEthernet0/0/4]port default vlan 3//lsw3
sys
[Huawei]vlan batch 2 to 3
[Huawei]interface g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 2
[Huawei]interface g0/0/3
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 3

第二步：配置交换器和路由器干道

//lsw1只有一个g0/0/0口接通lsw2
[Huawei]interface g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 3//lsw2需要配置lsw1的g0/0/2口
[Huawei]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type trunk
[Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan all
//和路由器的g0/0/1口
[Huawei]interface g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all //lsw3则需要配置和路由器的g0/0/1口
[Huawei]interface g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all

第三步：配置路由器

//和lsw2的接口
[Huawei]interface g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 2
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.1]ip address 192.168.1.1 24
Dec 10 2021 19:10:32-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[0]:The line protocolIP on the interface GigabitEthernet0/0/0.1 has entered the UP state. [Huawei-GigabitEthernet0/0/0.1]interface g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dot1q termination vid 3
[Huawei-GigabitEthernet0/0/0.2]arp broadcast enable
[Huawei-GigabitEthernet0/0/0.2]ip address 192.168.2.1 24
Dec 10 2021 19:11:01-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[1]:The line protocolIP on the interface GigabitEthernet0/0/0.2 has entered the UP state. //和lsw3的接口
[Huawei-GigabitEthernet0/0/0.2]interface g0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]dot1q termination vid 2
[Huawei-GigabitEthernet0/0/1.1]arp broadcast enable
[Huawei-GigabitEthernet0/0/1.1]ip address 192.168.3.1 24
Dec 10 2021 19:12:29-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[2]:The line protocolIP on the interface GigabitEthernet0/0/1.1 has entered the UP state. [Huawei-GigabitEthernet0/0/1.1]interface g0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]dot1q termination vid 3
[Huawei-GigabitEthernet0/0/1.2]arp broadcast enable
[Huawei-GigabitEthernet0/0/1.2]ip address 192.168.4.1 24


第四步：配置DHCP池

[Huawei]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[Huawei]ip pool vlan
Info: It&＃39;s successful to create an IP address pool.
[Huawei-ip-pool-vlan]network 192.168.1.0 mask 24
[Huawei-ip-pool-vlan]gateway-list 192.168.1.1
[Huawei-ip-pool-vlan]dns-list 8.8.8.8
[Huawei-ip-pool-vlan]q[Huawei]ip pool vlan2
Info: It&＃39;s successful to create an IP address pool.
[Huawei-ip-pool-vlan2]network 192.168.2.0 mask 24
[Huawei-ip-pool-vlan2]gateway-list 192.168.2.1
[Huawei-ip-pool-vlan2]dns-list 8.8.8.8
[Huawei-ip-pool-vlan2]q[Huawei]ip pool vlan3
Info: It&＃39;s successful to create an IP address pool.
[Huawei-ip-pool-vlan3]network 192.168.3.0 mask 24
[Huawei-ip-pool-vlan3]gateway-list 192.168.3.1
[Huawei-ip-pool-vlan3]
[Huawei-ip-pool-vlan3]dns-list 8.8.8.8
[Huawei-ip-pool-vlan3]q[Huawei]ip pool vlan4
Info: It&＃39;s successful to create an IP address pool.
[Huawei-ip-pool-vlan4]network 192.168.4.0 mask 24
[Huawei-ip-pool-vlan4]gateway-list 192.168.4.1
[Huawei-ip-pool-vlan4]dns-list 8.8.8.8
[Huawei-ip-pool-vlan4]q

第五步：为接口选择DHCP模式

[Huawei]interface g0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dhcp select global [Huawei]interface g0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dhcp select global [Huawei-GigabitEthernet0/0/0.2]interface g0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]dhcp select global[Huawei-GigabitEthernet0/0/1.1]interface g0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]dhcp select global
[Huawei-GigabitEthernet0/0/1.2]q
