Load Balancing: Load balancing is the process of distributing network traffic among multiple servers. No single server can handle such demand, so a balancer evens out the workload to ensure efficient application responsiveness.
Note: Before starting the configuration, we need to have the WANs already set up.
Configuration
1.- Access the device.
IP: 192.168.1.1 on the administration port (MGMT), can be accessed from any other IP configured on its ports.
Username: admin
Password: Configured the first time it is accessed.
Once inside the device interface, select the following section: Network -> Route/Load -> Load Balance.
2.- We are going to enable the load balancing option and click on "Custom Interface Weight" to configure the weights of the load balancing connections.
3.- It will display the following screen, and we fill it in with the following data:
Set the weight for the connections:
Example: Traffic will be distributed across multiple links based on the load of each WAN port. For instance, if the load for WAN and WAN1 is set to 3 and 2 respectively, 60% of the total traffic will be routed through WAN, and 40% through WAN1.
If you set it to 1 for each WAN, the connection will be 50% of the weight of the load on the connections.
Tip: By default, multiple link load balancing considers the bandwidth value as its weight. Users can adjust the weight under the following conditions. If the bandwidth usage of an interface is small/large, increase/decrease its weight to raise/lower the bandwidth usage.
So we already have our load balancing configured.
