Hello,

I have reviewed this document as part of the
Operational directorate's ongoing effort to review all IETF documents
being processed by the IESG. These comments were written with the intent
 of improving the operational
 aspects of the IETF drafts. Comments that are not addressed in last
call may be included in AD reviews during the IESG review. Document
editors and WG chairs should treat these comments just like any other
last call comments.

Summary: Ready with nits

***********************

So I know Section 4 is supposed to incorporate both types of GRE-in-UDP. You do
call out in Section 2.1.1 though that multicast is not appropriate for this
technology (See below). Then in section 4 you go into multicast by calling it
out (See below). Is there a way to map the multicast parts of this section
applying to TMCE udp-in-gre or would this confuse things?

Section 2.1.1

GRE-in-UDP tunnels are not appropriate for traffic that is not known to be
congestion-controlled (e.g., IP multicast traffic).

Section 4

GRE-in-UDP allows encapsulation of unicast, IPv4 broadcast, or multicast
traffic.

***********************

Section 8 - "Use of a "Circuit Breaker" for the tunneled traffic as described
in [CB]."

Is there a better reference that can be added? Not sure if you are describing
draft-ietf-tsvwg-circuit-breaker or another document.
