Andy,

I just reviewed this document, and am prepared to issue the LC for
publishing as Historic. I have two concerns. First, it seems that the
CEM header does not follow the "first nibble set to zero" which could of
course confuse ECMP implementations. I think it may be worth pointing
this out via a reference to RFC 4928. Something in Section 4 that looks
like:

Note: Setting the R bit to 1 violates the Best Current Practice defined
in RFC 4928 when operating on MPLS networks. In this situation, MPLS
networks could mistake a CEM payload as the first nibble of an IPv4
packet, potentially causing misordering of packets on the pseudowire in
the presence of MPLS ECMP in the MPLS network.

Second, you have this in the document...

It looks to me like 0x0008 was assigned to CEP, as referenced in RFC
4446 and RFC 4842. If CEM is also using this, we have more of a problem
than simply a typo here.

I would like to request that draft-malis-sonet-ces-mpls-07.txt be
published as a historical RFC. Mark Townsley will be the shepherding
AD.  This draft documents the IANA assignment of PWE3 PW type 0x0008,
and points to RFC 4842 as the standards-track protocol for this
application.
