Spanning Tree Protocol (STP) Basics | Why we use STP

Background till 6:20 ---- STP from 6:21 The basics or justification of using Spanning Tree Protocol (STP) in a network is discussed. STP helps to solve such problems of layer-2 looping. To do that, STP changes interface/port state either as Blocking State or Forwarding State Blocking State: A port in Blocking state can not forward or receive data frames Forwarding State: A port in forwarding state can send and receive data frames #STP #SpanningTreeProtocol
