Hi Jonathan,
I apologize for the fact that these comments/questions are late but offer
them anyway...
3. Applicability Statement
OLD:
Operationally, the scope of this protocol is administratively
determined. In other words, the scope of dissemination is determined
by routers configured to disallow transmission or reception of MPL
messages on a subset of interfaces.
This language predates the alignment with I-D.ietf-6man-multicast-scopes
and I suspect
it is no longer generally true. I recommend deleting it.
4.1. MPL Domains
OLD:
When MPL is used in deployments that use administratively defined
scopes that cover, for example, multiple subnets based on different
underlying network technologies, Admin-Local scope (scop value 4) and
/or Site-Local scope (scop value 5) SHOULD be used.
I'm not clear on whether, in deployments where scop values 4 and/or 5 are
in use, a node
should participate in the ALL_MPL_FORWARDERS multicast address for each
multicast
scope in use or just the highest scope in use.
5.4 MPL Forwarder Parameters
OLD:
PROACTIVE_FORWARDING A boolean value that indicates whether the MPL
Forwarder schedules MPL Data Message transmissions after receiving
them for the first time. It is RECOMMENDED that all MPL
Interfaces attached to the same link of a given MPL Domain use the
same value for PROACTIVE_FORWARDING and has a default value of
TRUE. The mechanism for setting PROACTIVE_FORWARDING is not
specified within this document.
SEED_SET_ENTRY_LIFETIME The minimum lifetime for an entry in the
Seed Set. SEED_SET_ENTRY_LIFETIME has a default value of 30
minutes. It is RECOMMENDED that all MPL Forwarders use the same
value for SEED_SET_ENTRY_LIFETIME for a given MPL Domain and has a
default value of 30 minutes. The mechanism for setting
SEED_SET_ENTRY_LIFETIME is not specified within this document.
NEW:
...
PROACTIVE_FORWARDING has a default value of TRUE.
...
It is RECOMMENDED that all MPL Forwarders use the same
value for SEED_SET_ENTRY_LIFETIME for a given MPL Domain and *use* a
default value of 30 minutes.
I think you were already planning to delete the RECOMMEND that all MPL
Interfaces
on the same link use the same value for PROACTIVE_FORWARDING. The second
suggestion is just grammatical.

- 'Multicast Protocol for Low power and Lossy Networks (MPL)'
<draft-ietf-roll-trickle-mcast-06.txt> as Proposed Standard
This is a second last call, the first one having been abandoned to send
the document back to the working group. But the latest revision addresses
comments that were received during the first last call.
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 2014-02-07. Exceptionally,
comments may be
sent to iesg(_at_)ietf(_dot_)org instead. In either case, please retain the

Abstract
This document specifies the Multicast Protocol for Low power and
Lossy Networks (MPL) that provides IPv6 multicast forwarding in
constrained networks. MPL avoids the need to construct or maintain
any multicast forwarding topology, disseminating messages to all MPL
Forwarders in an MPL Domain. MPL uses the Trickle algorithm to
manage message transmissions for both control and data-plane
messages. Different Trickle parameter configurations allow MPL to
trade between dissemination latency and transmission efficiency.
