Warren Kumari has entered the following ballot position for draft-ietf-bess-evpn-pref-df-11: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/about/groups/iesg/statements/handling-ballot-positions/ for more information about how to handle DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-pref-df/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Why are there two algorithms (Highest-Preference and Lowest-Preference)?[0] This seems operationally dangerous and will lead to additional operational complexity, tricky to debug behaviors, additional implementation complexity, etc. Assuming that there *is* a good reason (and "Well, we couldn't decide,, so... ¯\_(ツ)_/¯" isn't one) these should be a section helping operators decide which algorithm they should deploy, and the pro's and con's of each. [0]: I did try and find this, but the closest I got was a note in the Shepherd Writeup saying: "There was a "last minute" agreement on managing the highest/lowest pref algorithm using different DF algs rather than a single one+local configs." -- this doesn't actually answer the question. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I support John Scudder's DISCUSS, as well as his comments -- the Introduction seems quite incomplete, and just sort of throws the reader into the deep end.
