网络设计之DHCP服务器及spanning-tree portfast(生成树协议)

效果图

1、声明VLAN

vlan 1
no shutdown
exit
vlan 2
no shutdown
exit
vlan 3
no shutdown
exit
vlan 4
no shutdown
exit

2、给vlan配IP

10.0.0.1

interface vlan 1
ip address 10.0.0.1
no shutdown
exit
interface vlan 2
ip address 172.16.2.1
no shutdown
exit
interface vlan 3
ip address 172.16.3.1
no shutdown
exit

10.0.0.2

interface vlan 1
ip address 10.0.0.2
no shutdown
exit
interface vlan 4
ip address 172.16.3.1
no shutdown
exit

3、10.0.1.1配vlan和默认网关

interface vlan 1
ip address 10.0.1.1
no shutdown
exit
ip default-gateway 10.0.0.2

4、配端口

10.0.0.1

interface ethernet 0/0
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-4
switchport mode trunk
no shutdown
exit
interface ethernet 0/1
switchport access vlan 2
switchport mode access
no shutdown
exit

10.0.0.2

interface ethernet 0/0
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-4
switchport mode trunk
no shutdown
exit
interface ethernet 0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,4
switchport mode trunk
no shutdown
exit

10.0.1.1

interface ethernet 0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,4
switchport mode trunk
no shutdown
exit
interface ethernet 0/2
switchport access vlan 4
switchport mode access
no shutdown
exit

5、生成树协议

10.0.1.1

interface ethernet 0/2
spaningtree portfast
no shutdown
exit

6、主机配ip

172.16.1.2

ip 172.16.1.2 255.255.255.0 172.16.1.1

172.16.2.2

ip 172.16.2.2 255.255.255.0 172.16.2.1

7、配置DHCP服务

10.0.0.2

ip dhcp pool pool-name
network 172.16.3.0 /24
defult-router 172.16.3.1
dns-server 202.4.130.100 202.4.130.101

成功后是这个样子

完成！

要做到全部ping通

不然第一时间去no shutdown vlan
