基于Cisco ISL和IEEE 802.1Q的VLAN间通信原理及仿真分析

Principle of Communication and Simulation Experimental Analysis on VLAN Based on Cisco ISL and IEEE 802.1Q

采用Boson NetSim,基于Cisco ISL和IEEE 802.1Q组建了不同协议的VLAN间通信异构网络,设计了模拟拓扑图,分析了路由器的端口设置、IP地址分配以及配置命令,对虚拟通信网络进行了仿真测试,实现了不同协议的VLAN间通信,并在实际的网络设备上进行了实验验证,结果表明所组建的虚拟通信网络是可行的。

Based on Cisco ISL and IEEE 802.1Q,virtual network communication between different network protocols is developed by Boson NetSim.The simulation topological diagram is designed.Static routers ports are set and IP addresses are distributed.The configuration commands of the router and the two switches are analyzed respectively.Thus,the simulation test for the VLAN is carried out,achieving the virtual communication between VLAN.And the experimental tests in the real network prove the design of the virtual network is feasible.
