Fortigate SD-WAN Load Balacing

[tungnx59]

Dear Expert, 

I am searching Fortigate SD-WAN load Balancing, and I found 2 commands:

1.

set load-balance-mode [source-ip-based|weight-based|...]

This command is under : config system sdwan

And: 2. 

set load-balance [enable|disable]

This command under: config service (SD-WAN rule)

I don't understand what is purpose of them , and why do FortiGate SD-WAN has  these 2 commands look like same ?

Because, if traffic match sdw-wan rule, the command 2 will execute, right ?, and when command 1 is executed ?

Thanks !

The first one is based on which parameter of the load balance you want to configure

SDWAN does load balancing when it hits the implicit rule otherwise SDWAN rule will decide the outgoing interface based on various Interface selection strategy. 

1. set load-balance-mode [source-ip-based|weight-based|...] : it decide the strategy of load balancing. 

2. 

set load-balance [enable|disable]: It means load balancing is enabled.
