[palani2010]

I want to know sdwan technologies will do load balancing.

Vedge routers with Two transport connections.

Below output for your reference.

Hi,

yes, if you don't have Application Aware Routing (AAR) and Data Policy configured that may force one of the paths to be primary, then ECMP - load balancing will happen.

[palani2010]

Thank you. 

I don't have AAR configured and what is data policy i.e., if we have two links one is primary and other one is secondary. Correct me if i am wrong

Data policy is centralized policy type (also there is localized data policy) which changes user traffic path based on your policy configuration.

If you didn't do it, then your traffic will be ECMP i.e load balancing.

Yes, the default behavior is to do load balancing.
