Hope you all doing great. I need some help from you people, I have one router over which there are 2-3 WAN links getting terminated. Now both this links are from different ISP provider and moreover the IP address pool provided by them is from their own pool. So those are not universal public ip's.
My requirement is I want to achieve load balancing over this 2-3 links. Please help me as I am searching asolution for this from quite a long time. One thing came to my mind was configuring backup load under the interface but don't have any idea on it's working and also not sure whether it will work efficiently.
