写在前面
VLAN：VLAN（虚拟局域网）是对连接到的第二层交换机端口的网络用户的逻辑分段，不受网络用户的物理位置限制而根据用户需求进行网络分段。一个VLAN可以在一个交换机或者跨交换机实现。基于交换机的虚拟局域网能够为局域网解决冲突域、广播域、带宽问题。
OSPF：OSPF(Open Shortest Path First开放式最短路径优先）是一个内部网关协议(Interior Gateway Protocol，简称IGP），用于在单一自治系统（autonomous system,AS）内决策路由。
单臂路由：单臂路由（router-on-a-stick）是指在路由器的一个接口上通过配置子接口（或“逻辑接口”，并不存在真正物理接口）的方式，实现原来相互隔离的不同VLAN（虚拟局域网）之间的互联互通。
3.1、拓扑图
3.2、操作思路
1、5台PC先配置IP，配置接入层交换机VLAN，指定0/0/1为trunk链路，0/0/2和0/0/3配置为access链路。
2、两台路由配置单臂路由允许多个VLAN数据通过，封装dot1q协议，配置1/2/3/4网段网关地址，5/6网段配置IP。
3、三层交换配置VLAN、IP、接口类型为access。
4、最后对两台路由器、三层交换机配置OSPF，router_id分别为1.1.1.1、2.2.2.2、3.3.3.3 。
5、测试全网互通
3.3、配置操作
自行配置PC机地址，网关统一配置为1。
