CCNA - Spanning Tree Protocol - Part 1

Dive into the fundamentals of Spanning Tree Protocol (STP) and Cisco's Per-VLAN Spanning Tree (PVST) in this comprehensive video tutorial. Learn about network redundancy, layer 2 loops, and broadcast storms before exploring STP's role in preventing these issues. Understand the process of root bridge election, port role selection, and how STP blocks ports to prevent loops. Practice your knowledge with multiple quizzes throughout the lesson, identifying root bridges and port roles in various network scenarios. Gain insights into PVST and the Extended System ID, and conclude with an introduction to Boson ExSim for further CCNA exam preparation.
