STP (Spanning Tree Protocol)
STP (Spanning Tree Protocol) STP (Spanning Tree Protocol) – Table of Contents Redundancy. Why do we need STP. Example to explain Broadcast storm, Multiple frame copies, Mac table inconsistency. How STP works. BPDU (Bridge Protocol Data Unit) and Its Types. STP Election Process and STP Port states. BPDU Timers. Interview questions for Network Engineer asked from STP. • Redundancy: - Protecting the network from single point of failure is called redundancy. Single point of failure means that if one device/port/link goes down the traffic should failover or pass through the other device/port/link. - Failure of single network link, single device, or a critical port on a switch causes network downtime. - Redundancy is required in the network design in order to maintain high degree of reliability & eliminate any single point of failure. - Achieve redundancy in switches by connecting them with multiple links. - It reduce congestion & ...
