摘要
根据IEEE802.1D标准的STP协议格式设计了一个四元向量组,并采用向量组优先级比较的方法,应用仿真软件Dynamips与GNS3分析与实现了环形网络中生成树的构造和配置过程,通过查看命令分析了生成结果的正确性。并模拟网络断路故障演示STP利用备份链路恢复网络的连通性。实验结果表明,本实验可以真实地模拟STP协议的运行,有助于学生对STP原理的理解。
A vector included four elements was designed according to STP(Spanning Tree Protocol)defined in IEEE802.1D.Compared the priority of the vector,a loop network was constructed and a spanning tree was schemed by the software Dynamips and GNS3.The result of spanning tree was analyzed and proved validity through showing commands.Lastly,the character of STP utilizing the backup links to recover the network con-nectivity was exhibited by imitating link failure.The experiment of using the vector really simulates STP communication process and helps students to catch on STP principle.
