Spanning Tree
The spanning tree protocol is the protocol of layer 2. It can eliminate the ring cycle of layer 2 by
choosing to block the redundant links in the network, and it can back up the links.
Similar to other protocols, the spanning tree protocol is updated with the development of the
network: From STP (Spanning Tree Protocol), to RSTP (Rapid Spanning Tree Protocol), and to the
latest MSTP (Multiple Spanning Tree Protocol).

Step 2
STP
: The most basic spanning tree protocol.
RSTP
: Improved based on STP, and realizes rapid convergence of network topology.
MSTP
: Remedies the defects of STP and RSTP. MSTP not only realizes rapid convergence,
but also provides better load sharing mechanism for the redundant links by forwarding
the flow from different VLANs through their own paths.
