  |  Spanning Tree Algorithm

Overview

–  240  –

lowest cost spanning tree, it enables all root ports and designated ports, 

and disables all other ports. Network packets are therefore only forwarded 

between root ports and designated ports, eliminating any possible network 

loops.

Figure 101:  STP Root Ports and Designated Ports

Once a stable network topology has been established, all bridges listen for 

Hello BPDUs (Bridge Protocol Data Units) transmitted from the Root Bridge. 

If a bridge does not get a Hello BPDU after a predefined interval (Maximum 

Age), the bridge assumes that the link to the Root Bridge is down. This 

bridge will then initiate negotiations with other bridges to reconfigure the 

network to reestablish a valid network topology.

RSTP

 – RSTP is designed as a general replacement for the slower, legacy 

STP. RSTP is also incorporated into MSTP. RSTP achieves much faster 

reconfiguration (i.e., around 1 to 3 seconds, compared to 30 seconds or 

more for STP) by reducing the number of state changes before active ports 

start learning, predefining an alternate route that can be used when a node 

or port fails, and retaining the forwarding database for ports insensitive to 

changes in the tree structure when reconfiguration occurs. 

MSTP

 – When using STP or RSTP, it may be difficult to maintain a stable 

path between all VLAN members. Frequent changes in the tree structure 

can easily isolate some of the group members. MSTP (which is based on 

RSTP for fast convergence) is designed to support independent spanning 

trees based on VLAN groups. Using multiple spanning trees can provide 

multiple forwarding paths and enable load balancing. One or more VLANs 

can be grouped into a Multiple Spanning Tree Instance (MSTI). MSTP builds 

a separate Multiple Spanning Tree (MST) for each instance to maintain 

connectivity among each of the assigned VLAN groups. MSTP then builds a 

Internal Spanning Tree (IST) for the Region containing all commonly 

configured MSTP bridges.
