DHCP的详细步骤

DHCP的详细步骤
1、首先在SWA上分配vlan
SWA(config)#vlan 10
SWA(config-vlan)#exit
SWA(config)#vlan 20
SWA(config-vlan)#exit
SWA(config)#vlan 30
SWA(config-vlan)#exit
2、将F0/1-5加入vlan10 F0/6-10加入vlan20 F0/11-15加入vlan 30
SWA(config)#interface range fastethernet 0/1-5
SWA(config-if)#switchport access vlan 10
SWA(config)#interface range fastethernet 0/6-10
SWA(config-if)#switchport access vlan 20
SWA(config)#interface range fastethernet 0/11-15
SWA(config-if)#switchport access vlan 30
3、将F0/24端口设置为Trunk
SWA(config)#interface fastethernet 0/24
SWA(config-if)#switchport mode trunk
4、设置vlan10的ip为10.0.0.1 255.255.255.0 vlan20的ip为20.0.0.1 255.255.255.0
Vlan30的ip为30.0.0.1 255.255.255.0
SWA(config)#interface vlan 10
SWA(config-if)#ip address 10.0.0.1 255.255.255.0
SWA(config)#interface vlan 20
SWA(config-if)#ip address 20.0.0.1 255.255.255.0
SWA(config)#interface vlan 30
SWA(config-if)#ip address 30.0.0.1 255.255.255.0
5、进入路由器RB，开启dhcp服务器
RB(config)#service dhcp
6、设置地址池10、20、30并且设置动态Rip 2以及默认网关和建立dns RB (config)#ip dhcp pool 10
RB (dhcp-config)#network 10.0.0.0 255.255.255.0
RB (dhcp-config)#default-router 10.0.0.1
RB (dhcp-config)#dns-server 222.222.222.222
RB (config)#ip dhcp pool 20
RB (dhcp-config)#network 20.0.0.0 255.255.255.0
RB (dhcp-config)#default-router 20.0.0.1
RB (dhcp-config)#dns-server 221.221.221.221
RB (config)#ip dhcp pool 30
RB (dhcp-config)#network 30.0.0.0 255.255.255.0
RB (dhcp-config)#default-router 30.0.0.1
RB (dhcp-config)#dns-server 220.220.220.220
7、从路由器上的F0/0端口开启3个虚拟端口并设置IP
RB (config)#interface fastethernet 0/0.10
RB(config-subif)#encapsulation dot1Q 10
RB(config-subif)#ip address 10.0.0.1 255.255.255.0
RB (config)#interface fastethernet 0/0.20
RB(config-subif)#encapsulation dot1Q 20
RB(config-subif)#ip address 20.0.0.1 255.255.255.0 RB (config)#interface fastethernet 0/0.30
RB(config-subif)#encapsulation dot1Q 30
RB(config-subif)#ip address 30.0.0.1 255.255.255.0。
