What Is STP?
Spanning Tree Protocol (STP) is a web connection protocol building a loop-free logical topology for Ethernet networks.
Its basic function is to prevent bridge loops and broadcast radiation that results from them.
If an active link fails, STP enables a internet design to include backup links to provide fault tolerance.
It creates a spanning tree that characterizes the relationship of nodes within a internet of connected layer-2 bridges.
STP was originally standardized as IEEE (Institute of Electrical and Electronics Engineers) 802.1D.

Actually, it is one of the STP standards.
The IEEE introduced RSTP () as 802.1w in2001.
RSTP is backward compatible with the standard STP.
The standard IEEE 802.1D-2004 incorporates RSTP and obsoletes the original STP.
MSTP makes use of Bridge Protocol Data Units (BPDUs) to exchange information between spanning tree compatible devices.
Those Bridges, Regions, and LANs are connected into a single Common Spanning Tree (CST).
CSTs are backward compatible with the STP and RSTP.
An MST that has a single VLAN assigned to it is an IST (Internet Spanning Tree).
Sometimes, you may encounter the web link protocol error such as web link protocol is missing.
This post provides some methods to help you fix the error.
MSTP was originally defined in IEEE 802.1s-2002 and later merged into IEEE 802.1Q-2005.
It defines an extension to RSTP to further develop the usefulness of virtual LANs.
PVST vs RSTP
Still, lets learn what does PVST stand for first.
It uses its own proprietary ISL (Inter-Switch Link) for VLAN encapsulation while PVST+ uses 802.1Q VLAN encapsulation.
Cisco also published a proprietary version of RSTP called Rapid Per-VLAN Spanning Tree (RPVST).
RPVST creates a spanning tree for each VLAN like PVST.
