hi , As per my knowledge, In present condition , Whenever you will remove or add any link or logical link in Ex router , it will rehash again and flow is always expected to move. They have not implementation of consistant hashing in Ex-series. but in new releases of s/w for Mx series, they had implemented consistant hashing feature. Where if one of link goes down still other flow in other links will be impacted. And regarding to flow, where exactly it is taking path, I have a suggestion , If you apply firewall filter for appropriate source address for counting that, you can found out for where it it going.
