摘　　要：VLAN技术可以有效隔离广播风暴,但同时也会使不同VLAN之间的通信产生隔离。为了解决VLAN间的通信问题,必须借助具有三层IP技术的路由器来实现。单臂路由技术是比较典型的三层技术解决方案,它可以有效弥补三层网络设备端口数量有限的缺陷,并利用干道技术和子接口技术实现VLAN间的互通。本文利用Cisco Packet Tracer 6.2模拟软件对单臂路由技术进行了网络仿真和结果验证,并给出相应配置命令。VLAN technology can effectively isolate broadcast storms,but it will also isolate the communication be⁃tween different VLANs.In order to solve the problem of communication between VLANs,routers with three-layer IP technology must be used.Single arm routing technology is a typical three-layer technology solution,which can effec⁃tively make up for the limitation of the number of ports in the three-layer network equipment,and realize the inter⁃working between VLANs by using trunk technology and sub interface technology.This paper used Cisco Packet Trac⁃er 6.2 simulation software to simulate the single arm routing technology and verify the results,and gave the corre⁃sponding configuration commands.
