3.3.1 Example of a system configuration using the Ring Protocol and STP for load balancing
Using the ALAXALA Ring and STP at the same time allows you to configure a network that provides
redundancy in both protocols and also implements load balancing. The following figure shows an example of
such configuration.
Figure 3.3-2 Building network using the Ring Protocol with STP
Two AX3630S series switches are used as core switches, and one of them is specified as the master node of
the Ring Protocol that runs on the backbone network. VRRP is also used because the Switches serve as a
gateway for data forwarding from terminals on each floor to the server and for forwarding between floors.
On floors 1 and 2, two redundant AX2430S series switches are used as the distribution switches and AX1230S
series switches are used as the access switch. STP is enabled on these switches.
On floor 1, MAC VLAN, which is often used for authentication, runs on the network, and Rapid (single) STP
is used to connect to the backbone network. (Authentication and MAC VLAN settings are not described here.)
On floor 2, assuming that different VLANs are used for different departments, Rapid PVST+ with a port
VLAN is used to connect switches to allow STP control on a per-VLAN basis.
In the server farm, an AX2430S series switch is used as the access switch, and Rapid PVST+ is used to
connect the switch to the core switches. Load balancing is attempted by using the per-VLAN control
functionality of PVST+.
