If there are 3 sites connected in a chain with WAN in between each other:
Site A ---- Site B ---- Site C
Each site has a WAE device. Traffic between A and C is optimized by their WAE, but the traffic goes through B, which also has a WAE.
How does the WAE at site B identify the traffic is already optimzed? Does it try to optimize again or just pass through?
Thanks a lot
