I have not been able to find an answer to this in the searching I have done. Does ECMP take into account the current load on the paths before choosing a path? We are using 'balanced round robin' on our metro-e links between locations, we have two providers with identical bandwidth at each location. My question is this: lets say a backup session starts from location A to B, and it is placed on path "2", and that session uses 80% of the bandwidth. Path "1" is only at 10% utilization, and the next session is placed on path "1" because of round robin. Now the 3rd session starts and is placed on path "2" again, and let say that utilization is now at 99% on path 2 and path one is at 20%. Will path 2 continue to take every other session or does the algorithm realize that path "1" is underutilized and favor that path?
