网络组建中常用路由器、单臂路由、三层交换机等三层设备连接不同的网段，上述网络设备之间互连并运行路由协议可以实现设备之间所连网段的互访，因此三层网络设备之间正确互连是网络组建的基础。对初学者来说路由器之间互连比较易于理解，但路由器与三层交换机或单臂路由与三层交换机等其他情形的三层设备之间如何互连就不易掌握。利用“功能等价法”可以解决这一问题，即将物理端口充足的路由器之间的互连方法确定为标准方法，通过和标准方法进行功能类比来确定其他情形三层设备互连的配置方法。

Router , router-on-a-stick and Layer 3 switch are used to connect different network in network con-struction, The network connected on the above network devices can visit each other by the routing protocol, so proper interconnection between layer 3 network devices is the foundation of the network construction .It’s easy to understand how to interconnect routers for beginners, but it’s hard to understand how to interconnects router and Layer 3 switch or other cases. The method of "functional equivalence" can be used to solve the prob-lem. This method treats the interconnection between the routers with enough physical ports as the standard method. The method of other cases of equipments interconnection can be got by analoging the basic method.
