You heard the words Spanning Tree, now it is time to understand what it is all about. We start with the very beginning, discussing how L3 uses a mechanism to prevent loops. We quickly find out that L2 does not have this mechanism and why Spanning Tree is needed. Then we enter the world of Spanning Tree. Exploring how spanning tree forms it topology and the election processes.
