Hi @piaakit1210,

 

The priorities are configured under Network > SD-WAN > SD-WAN Zones > SDWAN members. The member with lower priority value will be the primary. Make sure your default route is pointing to SDWAN. 

 

For load balancing, you can give SDWAN members the same priority and use SD-WAN rule to select Load Balancing Algorithm.
