Balancing between two internet channel on the sdwan

Can sdwan balance traffic between 2 isps refer from bandwidth?

Hi,

For overlay traffic it is load-balanced per hashing result for next-hop.

For DIA traffic, normally it is load-balanced (again, based on hashing result) and NATed to respective interface/pool/loopback based on WAN interface config. You can also have centralized data policy where you set local-tloc for primary DIA exit interface.

but it doesn't depend to bandwidth on the interfaces? I mean if we have two ISP providers:

ISP A - 1Gb

ISP B - 500Mb

you may use "weight" parameter to better load sharing, but it will work for overlay traffic. I've never seen document that describes "weight" for NAT DIA.
