The Spanning Tree Protocol (STP) Attacks (Layer 2) + Understand the Basics
Spanning Tree Protocol (TP) is a network layer protocol that aids in the creation of a logical loop-free topology for ethernet networks. With the passage of time, several improved implementations of STP entered the industry, introducing new changes to the protocol:
802.1D / STP (Original STP)
PVST+ is a combination of PVST and PVST (Cisco improvements of STP, adding a per VLAN feature)
802.1W / RSTP (Improved STP with much faster convergence)
Rapid PVST+ (Cisco improvement of RSTP, adding per VLAN feature)
