MPLS folks,
    the IESG has reviewed draft-ietf-mpls-icmp-02.txt and has decided not
advance its publication for two reasons.

    First, the IESG and a handful of folks in the community feel that including
information that exists at the sub-IP layer in ICMP is a "layer violation" and
not entirely backward compatible with RFC 1122 and RFC 1812
(the draft does not directly address what happens to a host that receives
this ICMP extension and does not support it).

    Second, the utility that the draft is addressing is generally very useful for
diagnosing problems with other types tunneling protocols in addition to MPLS.
For this reason, we would like to start a design team, headed
by Ron, to develop more generalized version of what these extensions
were designed to address.

thanks,
