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.
