一、实验拓扑图

1.VLAN规划：

        PC1：VLAN10

        PC2：VLAN20

        PC3：VLAN30

        PC4：VLAN40

        LSW1与LSW2互联链路：VLAN100

2.路由协议：

        OSPF单区域area 

3.实验目标：

        全网可达

4.网段规划：

VLAN	网关地址	网段
VLAN10	192.168.10.1/24	192.168.10.0/24
VLAN20	192.168.20.1/24	192.168.20.0/24
VLAN30	192.168.30.1/24	192.168.30.0/24
VLAN40	192.168.40.1/24	192.168.40.0/24
VLAN100（互联）	LSW1：192.168.100.1；LSW2：192.168.100.2	192.168.100.0/24

三、实验验收命令

1、查看接口VLAN划分情况

display port vlan active

2、查看三层接口IP简要信息

display ip interface brief

3、查看OSPF进程全部配置

ospf 1
display this

4、查看OSPF邻居简表，确认邻居Full

display ospf peer brief

5、只查看OSPF学习到的路由条目

display ip routing-table protocol ospf

6.DHCP下发IP情况

PC1:

PC2:

PC3：

PC4：

四、验证全网可通
