ospf+vlan实验
分析：
1 .划分IP段
2. ospf划分区域，进行手工配置
3 .ospf 密文认证 MD5加密
4.配置环回地址，使用缺省路由对R5接口不能宣告

vlan实验：
分析：
1.在交换机上创建两个虚拟广播域VLAN 10和VLAN 20
2.配置交换机各个接口
3.交换机与pc间设置成access链路，交换机与交换机、路由间设置成trunk链路
4.配置路由器
5.DHCP地址下发
四、实验过程
1.配置交换机 创建两个虚拟广播域 vlan 10 和vlan 20

2.在交换机上查看配置的vlan
3.配置路由器，创建对应的IP池，打开arp广播功能，最后进行DHCP地址下发
4.pc端打开DHCP，自动获取IP地址
