1、要求:
现有一台路由器,一台交换机,一台服务和两台PC机。要求模拟三个不同VLAN网段,两台PC机和一台服务器分别在不同的VLAN中,其中服务器为DHCP服务器,其中DHCP服务器能够为其他两个VLAN提供自动分配IP地址。
2、网络拓扑图:
网络拓扑图如图1所示:
图1:网络拓扑图
3、设备的配置
(1)路由器的配置:
[Router-Ethernet0]int eth0.1
[Router-Ethernet0.1]vlan-type dot1q ?
vid VLAN id
[Router-Ethernet0.1]vlan-type dot1q vid 10
[Router-Ethernet0.1]ip add ?
X.X.X.X IP address
[Router-Ethernet0.1]ip add 192.168.1.1 ?
X.X.X.X IP subnet mask
INTEGER<8-30> IP subnet mask length
[Router-Ethernet0.1]ip add 192.168.1.1 24
[Router-Ethernet0.1]
%01:09:38: Line protocol ip on the interface Ethernet0.1 is UP
[Router-Ethernet0.1]ip relay-address 192.168.3.100 //配置中继
[Router-Ethernet0.1]int eth0.2
[Router-Ethernet0.2]vlan-type dot1q vid 20
[Router-Ethernet0.2]ip add 192.168.2.1 24
[Router-Ethernet0.2]
%01:10:30: Line protocol ip on the interface Ethernet0.2 is UP
[Router-Ethernet0.2]ip relay-address 192.168.3.100 //配置中继
[Router-Ethernet0.2]int eth0.3
[Router-Ethernet0.3]vlan-type dot1q vid 30
[Router-Ethernet0.3]ip add 192.168.3.1 24
[Router-Ethernet0.3]
%01:12:36: Line protocol ip on the interface Ethernet0.3 is UP
(2)交换机的配置:
<Quidway>system-view
[Quidway]vlan 10
[Quidway-vlan10]
[Quidway-vlan10]vlan 20
[Quidway-vlan20]vlan 30
[Quidway-Ethernet1/0/10]port access vlan 10
[Quidway-Ethernet1/0/10]int eth1/0/20
[Quidway-Ethernet1/0/20]port acc
[Quidway-Ethernet1/0/20]port access vlan 20
[Quidway-Ethernet1/0/20]int eth1/0/24
[Quidway-Ethernet1/0/24]port
[Quidway-Ethernet1/0/24]port ac
[Quidway-Ethernet1/0/24]port access vlan
[Quidway-Ethernet1/0/24]port access vlan 30
[Quidway-Ethernet1/0/22]port link-type trunk ?
<cr>
[Quidway-Ethernet1/0/22]port link-type trunk
[Quidway-Ethernet1/0/22]port trunk permit vlan all
Please wait........................................... Done.
(3)服务器的配置:
这里是用2003作为DHCP服务器配置的,具体操作如下;
第一步:打开控制面板----->添加/删除Windos组件,然后如图2操作:
图2:添加网络和应用程序服务
此时点击详细信息可以看到DHCP已经被选上了,然后点击下一步,此时会看在安装配置组件。
第二步:安装完成后点击管理工具,会看到DHCP然后点击,接着出现一对话框,点击DHCP右击,如图3所示:
图3:新建作用域
第四步:点击新建作用域配置VLAN10makt的DHCP,具体如图4所示:
图4:配置VLAN10自动获取的DHCP
第五步:点击下一步,出现排除网段的对话框,如图5所示:
图5:排除
第六步:点击下一步,下一步一直到配置网关和DNS操作,如图6和图7所示:
图6:配置默认网关配置
图7:DNS配置
然后点击下一步,下一步就完成了,VLAN20 tec的DHCP的配置与上面类似。
然后测试DHCP服务是否能够与自己的网关能否ping通,以及能否ping通路由器的其他IP,操作如图8、9、10所示:
图8:ping自己的网关
图9:ping 192.168.2.1
图10:ping 192.168.1.1
(4)PC-B的配置和验证DHCP的分配以及DNS的获得
用一台防火墙模拟PC-B,具体配置如下操作:
<FW-3>system-view
System View: return to User View with Ctrl+Z.
[FW-3]sysname PC-A
[PC-A]sysname PC-B
[PC-B]interface e
[PC-B]interface Ethernet0/0
[PC-B-Ethernet0/0]undo ip add
[PC-B-Ethernet0/0]undo ip add dhcp-alloc
[PC-B-Ethernet0/0]ip address dhcp-alloc
验证:
[PC-B]dis int et0/0
Ethernet0/0 current state :UP
Line protocol current state :UP
Description : Ethernet0/0 Interface
The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
Internet Address is 192.168.2.2/24, acquired via DHCP
[PC-B]dis dns server dynamic //查看自动获取DNS
Domain-server IpAddress
0 1.1.1.1
1 2.2.2.2
(5)PC-B的配置和验证DHCP的分配以及DNS的获得
用一台防火墙模拟PC-A,具体配置如下操作:
<PC-A>system-view
System View: return to User View with Ctrl+Z.
[PC-A]int et0/0
[PC-A-Ethernet0/0]undo ip add d
[PC-A-Ethernet0/0]undo ip add dhcp-alloc
[PC-A-Ethernet0/0]ip add dh
[PC-A-Ethernet0/0]ip add dhcp-alloc
验证:
[PC-A]dis int et0/0
Ethernet0/0 current state :UP
Line protocol current state :UP
Description : Ethernet0/0 Interface
The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
Internet Address is 192.168.1.2/24, acquired via DHCP
[PC-B]dis dns server dynamic //查看自动获取DNS
Domain-server IpAddress
0 1.1.1.1
1 2.2.2.2
