May be one suggestion, trying to address Tom's comment, and inspired by RFC 4360: https://tools.ietf.org/html/rfc4360#section-3.1 OLD: Local Data Part 1: A four-octet operator-defined value. Local Data Part 2: A four-octet operator-defined value NEW: Local Data Part 1: A four-octet value. The format and meaning is defined by the Autonomous System set in the Global Administrator field. Local Data Part 2: A four-octet value. The format and meaning is defined by the Autonomous System set in the Global Administrator field. Or some other wording, but I think the point is that "operator-defined" means the operator of the AS set in the Global Administrator field. --Bruno > -----Original Message----- > From: Idr [mailto:idr-bounces@ietf.org] On Behalf Of t.petch > Sent: Thursday, October 20, 2016 10:38 AM > To: Jared Mauch > Cc: IETF IDR WG; Sue Hares > Subject: Re: [Idr] WG LC on draft-ietf-idr-large-community-03.txt (10/17/2016 to > 10/31/2016) > > Jared > > As Brian has pointed out, it was the use of 'usually' that I was > concerned with, as watering down the recommended use of an ASN by > RFC1997.
