The IESG has received a request from the Multiprotocol Label Switching WG

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf(_at_)ietf(_dot_)org mailing lists by 2008-04-25. Exceptionally,

I did not look into this in detail because I claim no expertise in
MPLS, but...
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?
