Hi, Well, everyone has to support the default DF Alg, based on RFC7432. So that one for sure. And in addition there are others that have been implemented. For instance, Pref DF election has been implemented by multiple vendors. Thanks, Jorge

I am just asking which algorithm is most widely implemented/used for electing the DF *and* BDF for EVPN VPWS single-active multihoming.

And I don’t see why you would use something different? In other words, if you use e.g., Pref based DF Alg, use it for DF and BDF elections. Only that the BDF election excludes the DF from the candidate list.
