A few years ago we did a presentation about what can happen if hashing
for load balancing purposes doesn't work well (be it either IP or L2VPN
traffic). I think some of the information is still relevant as there
really isn't much difference between the problem existing in the
underlay network's implementation of algorithms or the properties of the
enveloppe that encompasses the overlay network packet.
