STP (Spanning Tree Protocol) is a Layer-2 protocol that builds a loop-free network topology. Only one active path can exist between two stations in order for them to function properly. STP is a Network Protocol (Layer2) and has a Standard of IEEE 802.1D/W/S/Q, Cisco (Def on Cisco=PVST). Its function is to prevent Layer2 Loops within a network topology, adapt to network changes and failures. The STP Algorithm was designed by Radia Perlman. Spanning Tree Protocol has a Multicast Address of 01:80:C2:00:00:00, 01:00:0C:CC:CC:CD (Cisco’s PVST). There are 5 STP port states and 3 RSTP port states. Likewise, there are 3 STP Read More …
