I have a scenario where I have 2, but could end up being 3 leaves(leaf switches) that will belong to the same ESI. I want to be able to control which of one of these 2(or3) leaves will be the elected DF(designated forwarder). I know on the MXs, there is a knob that allows for changing the DF election algorithm from mod5 to being preference based that I've tested and it works, but on the QFX's this knob does not exist. How can I influence the DF election process on the QFXs? I've read over the RFCs on this as well as the EVPN Guide which can be found here:

Thanks in advance to any insight provided!!
