模拟简单校园网络

思科模拟简单校园网

一、二层交换机配置，划分vlan

宿舍vlan10，教学楼vlan20，宿舍网为1.1.1.0/24网段，教学楼网段为2.2.2.0/24网段

1.DHCP服务器配置

桌面–>IP配置–>配置相关vlan网段的网关，子网掩码

DHCP（宿舍）

思科模拟简单校园网

2.宿舍交换机配置

fa0/2 vlan 10
fa0/1 trunk

Switch#config
Switch#configure t
Switch#configure terminal 
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#hostname sw1
sw1(config)#vlan 10
sw1(config-vlan)#exit
sw1(config)#int
sw1(config)#interface f
sw1(config)#interface fastEthernet 0/2
sw1(config-if)#sw
sw1(config-if)#switchport a
sw1(config-if)#switchport access v
sw1(config-if)#switchport access vlan 10
sw1(config-if)#exit
sw1(config)#in
sw1(config)#interface f
sw1(config)#interface fastEthernet 0/1
sw1(config-if)#sw
sw1(config-if)#switchport m
sw1(config-if)#switchport mode t
sw1(config-if)#switchport mode trunk 

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

sw1(config-if)#
sw1(config-if)#exit
sw1(config)#

同理配置两个教室交换机sw1、sw2,配置vlan 20

3.交换机sw0配置

分别给DHCP（宿舍）、DHCP（教学楼）划分vlan，用于各个网段的DHCP配置，其他接口设置为trunk模式

DHCP配置成功，终端自动获取ip信息
思科模拟简单校园网

此时相同vlan的设备可ping通，不同vlan设备不可通

4.三层交换机配置

首先配置设备4三层交换机的vlan功能，实现交换机的功能

Switch>
Switch>
Switch>en
Switch#conf
Switch#configure t
Switch#configure terminal 
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#h
Switch(config)#hostname 4
4(config)#vlan 20
4(config-vlan)#exit
4(config)#int
4(config)#interface vl
4(config)#interface vlan 20

%LINK-5-CHANGED: Interface Vlan20, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up
4(config-if)#ad
4(config-if)#ip
4(config-if)#ip ad
4(config-if)#ip address 2.2.2.254 255.255.255.0
4(config-if)#no sh
4(config-if)#no shutdown 
4(config-if)#exit

ping测试：此时相同vlan内的设备可以相互ping通

5.宿舍vlan的路由设置（内网2设置）

Router>
Router>en
Router#conf
Router#configure t
Router#configure terminal 
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#h
Router(config)#hostname 2
2(config)#int
2(config)#interface f
2(config)#interface fastEthernet 0/0
2(config-if)#no sh
2(config-if)#no shutdown 

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

2(config-if)#exit
2(config)#int
2(config)#interface f
2(config)#interface fastEthernet 0/0.10

%LINK-5-CHANGED: Interface FastEthernet0/0.10, changed state to up
2(config-subif)#

2(config-subif)#ip ad
2(config-subif)#ip address 1.1.1.254 255.255.255.0
2(config-subif)#exit
2(config)#ro
2(config)#router r
2(config)#router rip 
2(config-router)#ne
2(config-router)#network 1.1.1.0
2(config-router)#exit

和终端宿舍1ping测试：可以通
