some ixp operators (e.g. me) are rather enthusiastic about the idea of a modified form of draft-raszuk-wide-bgp-communities getting more traction. This would solve this particular problem and many others.
Wide communities is the wrong tool here. You want this: http://tools.ietf.org/html/draft-ietf-idr-as4octet-extcomm-generic-subtype-0...
This draft does not cater for the use case of describing a 32-bit ASN peering with a 32-bit route server, which would require a 4-byte Global Administrator as well as a 4-byte Local Administrator sub-field. Kind regards, Martin
