一 需求分析
本实验的目的在于建立小型局域网。由于公司由财政部、人事部、科技部三个部门组成,分布在同一个交换机下。设计以下网络:三个个部门使用两台交换机连接,然后连接到汇聚交换机,再通过路由器与外网以及其他部门网络相连。为了控制网络上的广播风暴,增加网络的安全性,在交换机上需要设置VLAN,公司内部使用动态路由OSPF协议,所有主机均可通过dhcp自动获取ip地址。
二 规划拓扑
划分vlan:
vlan10 | 财政部 |
vlan20 | 人事部 |
vlan30 | 科技部 |
ip地址规划:
部门 | 网段 | 网关 |
财政部 | 192.168.10.0/24 | 192.168.10.254 |
人事部 | 192.168.20.0/24 | 192.168.20.254 |
科技部 | 192.168.30.0/24 | 192.168.30.254 |
设备 | 接口 | ip地址 |
LSW1 | valnif99 | 12.1.1.1/24 |
R1 | g0/0/1 | 12.1.2.2/24 |
R1 | g0/0/0 | 23.1.1.2/24 |
R2 | g0/0/0 | 23.1.1.3/24 |
汇聚交换机配置dhcp功能,员工无需手动配置ip
采用一个汇聚交换机,两个二层交换机,汇聚交换机开启dhcp服务,合理划分vlan、利用trunk和access口
三 拓扑图

interface Vlanif20
ip address 192.168.20.254 255.255.255.0
interface Vlanif30
ip address 192.168.30.254 255.255.255.0
4.3配置dhcp服务
LSW1:
配置全局地址池
ip pool vlan10//配置全局地址池
gateway-list 192.168.10.254
network 192.168.10.0 mask 255.255.255.0
#
ip pool vlan20
gateway-list 192.168.20.254

#
ip pool vlan30
gateway-list 192.168.30.254
