Creating the SD-WAN interface
- Go to Network > SD-WAN.
- Set the Interface State to Enable.
- Under SD-WAN, add the two WAN interfaces.
- Under Load Balancing Algorithm, select Volume and set the WAN1 interface to serve more traffic.
In this example, the ISP connected to WAN1 is a 40Mb link and the ISP connected to WAN2 is a 10Mb link, so we balance the Weight 75% to 25% in favor of WAN1.
- To help visualize the effectiveness of the algorithm, the SD-WAN Usage graph shows you the Bandwidth and Volume usage.
