Thanks for helping clarify. I'm not seeing what guarantees that the first octet of the RD is always zero going forward, though -- I see https://www.iana.org/assignments/route-distinguisher-types/route-distinguisher-types.xhtml that lists values 3-65534 as "Unassigned". If we are going to rely on non-overlap between the extended community types used for this document and RD types in general, don't we need to mark some values in one (or both!) registry as Reserved with a reference to [this-document]? -Ben _______________________________________________ BESS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bess
