I find it hard to make or accept quantative statements in this context, I know some ISP that scrub all communities, and I know some ISPs that pass on as much communities as possible. The market will decide. > Should we clearly define whether LargeCommunity should act different > from (or the same with) the RFC1997's Community? I consider it a feature that the behaviour is exactly aligned with RFC1997 communities. Some OTT operators might desire slightly different behaviour, but that is really a commercial dicussion outside of IETF scope. Thanks for the feedback. Kind regards, Job
