Redundant links are often used for link backup and network reliability in the Ethernet
switching network. However, such links will generate loops on the switching network,
leading to broadcast storm, unstable MAC address list and other faults, thus worsening
users’ communication quality, or even interrupting the communication. As a result, STP
(Spanning Tree Protocol) appears.
Same with the development of other protocols, from the original STP defined in IEEE
802.1D, to RSTP (Rapid Spanning Tree Protocol) defined in IEEE 802.1W and to MSTP
(Multiple Spanning Tree Protocol) defined in IEEE 802.1S, STP keeps upgrading.
MSTP is compatible with RSTP and STP while RSTP is compatible with STP. The
contrast among these 3 protocols is shown in the table.

Characteristic
Application
STP
A tree rid of loops as the solution to
broadcast storms and redundant backups.
It converges slowly.
All VLANs can be shared
without discrimination in user
or business flow.
RSTP
A tree rid of loops as the solution to
broadcast storms and redundant backups.
It converges rapidly.
MSTP
A tree rid of loops as the solution to
broadcast storms and redundant backups.
It converges rapidly.
Spanning trees balance the load among
VLANs. Flow of different VLANs will be
forwarded subject to paths.
Distinguish the user and
business flow for load sharing.
Different VLANs forward the
flow through separate
spanning trees.
After STP is deployed, the following objectives can be achieved by calculating the loops
with topology:
⚫ Loop elimination: eliminate possible communication loops by blocking redundant
links.
⚫ Link backups: activate redundant links to restore network connectivity if the active
path fails.
