I believe this document needs a normative reference to draft-ietf-mpls-upstream-label (now in Last Call) because the whole concept of upstream labels is introduced in that document and it seems vital to understanding and implementing this RFC. IANA considerations section should describe how IANA should reword the "unicast codepoint" and "multicast codepoint" assignment fields. It seems clear that these should be renamed to better reflect the reality introduced in this document. The document does not describe the impact (of lack thereof) of redefining the usage of existing codepoints and modifying existing standards (e.g. the MPLS-in-IP and MPLS-in-GRE encapsulation rules and what may or may not happen in a non-compliant decapsulator). Section 6 gives instructions how to handle unicast and multicast destination address. It does not describe how to handle the v4 255/8 broadcast address and it's debatable which category would apply if a packet was sent to a regular broadcast address such as 192.0.2.255/24. Should this be described for completeness or explicitly declared out of scope? editorial comment ----------------- Abstract is a bit long and has a typo: s/The former "multicast codepoint"/The latter "multicast codepoint" -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
