Hi,

As a reminder, draft-ietf-idr-reserved-extended-communities currently proposes to use the AS number O to get a global space of "generic four-octet AS specific" extended community (as defined in draft-ietf-idr-as4octet-extcomm-generic-subtype) in order to be able to get IANA assigned extended communities values from. (i.e. the equivalent of formerly "well known" RFC 1997 communities).

Following some discussion on draft-ietf-idr-as0, another option is to use AS number 0x0000FFFF instead of AS 0. This seems also more in line with RFC 1997 which use the same AS number (0xFFFF) for the same purpose (IANA assigned communities).

Comments welcomed.

In the absence of objection within 2 weeks, I'll update the draft accordingly (:s/0/0x0000FFFF).

Thanks
Regards,
Bruno
