The implementations I know use the same DF Alg for DF election _and_ backup DF Election. 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.

Thx
Jorge

Subject: [bess] BDF Election in EVPN VPWS Single-Active Multihoming

While RFC 8214 doesn't recommend any DF election algorithm capable of electing the BDF in EVPN VPWS single-active multihoming for deciding the backup PE, any feedback on what is(are) the widely implemented/supported DF election  algorithm(s) by vendors?

Regards,
Muthu
