3.3 Example of combined use of the Ring Protocol and STP in a building network
The ALAXALA Ring Protocol can be used with STP. This provides various functions, such as simultaneous
use of redundant configuration through STP and load balancing with distributed VLANs by the Ring Protocol.
Figure 3.3-1 Building network system with the Ring Protocol and STP configuration
Using STP and the ALAXALA Ring allows for not only a redundant configuration between neighboring nodes
but also an STP redundant configuration between any nodes in the ring.
In addition, you can use any combination of the single STP, PVST+, and Multiple Spanning Tree, depending
on your needs. For example, if you want to use multiple VLANs and perform load balancing per access switch
(per VLAN), you can use PVST+. If you want to support the protocol VLAN or MAC VLAN, you can use the
single STP.
