基于eNSP的二层VLAN虚拟仿真实验

基于二层VLAN的仿真实验,阐述了VLAN的概念、划分方式和接口类型。针对局域网内缺乏三层路由设备的场景下,从二层VLAN传统教学实验出发,设计了跨交换机VLAN、Mux VLAN、非对称VLAN模型3个实验。利用e NSP软件仿真二层VLAN 3个实验,实验给出了详细的设计方法、配置过程,并对实验结果进行了验证和分析。通过实验证明,在没有三层路由设备的情况下,二层VLAN之间也可以实现不同网段之间相互通信与隔离,可以运用在特定的网络环境下,让学生能够从理论上和实践上更好地掌握VLAN技术。...

This article is based on the two-layer VLAN simulation experiment, expounds the concept, the division method and the interface type of VLAN. In view of the lack of three-layer routing devices in the LAN, starting from two- layer VLAN on the traditional teaching experiment, the article designs three experiments i. e. , the across switches VLAN, Mux VLAN, asymmetric VLAN. Using the eNSP software, simulation is used to achieve the three experiments on the two-layer VLAN. The article shows the detailed design method and the configuration process, and makes the validation and analysis the result of the experiment. Experiments show that in the absence of three-layer routing devices, the two-layer VLAN can also realize the communication and isolation between different netwo
