Let's not do it. I disagree. The EDNS0 OPT RRSet is needed and thus if can not be fitted entirely a TC bit has to be set. Also 2181 was before EDNS0 so IMHO it doesn’t apply here anyway. EDE is all is new stuff we have to decide over what do with it now and not some ancient RFC. And a lot of people (including me) have said that they, because of the rare cases this appears, see TC as the right solution as it is simple and backwards compatible. EDE already is complex we should not increase it complexity for a rare corner case. So long -Ralf —-- Ralf Weber
