Be ye not afraid.

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 primarily for the benefit of the operational area directors.
Document editors and WG chairs should treat these comments just like any other
last call comments.


Document: draft-ietf-l2vpn-ipls-14
Reviewer: Warren Kumari

Summary: Looks good, with nits.

Note: The document states: "At this point, no further action is
planned to update this document and is published simply as a historic
record of the ideas."

AFAICT, this means that many of the OpsDir review checklist things do
no apply...

2.1 Terminology section, definitions don't have consistent indentation
(some are hanging indent, some no indent, etc.)

9.3
O: It is important to note that the frames
   sent to the control plane is applied stricter rate limiting
criteria to avoid overwhelming the control plane under adverse
conditions
   such as Denial Of Service attack.
P: It is important to note that stricter rate-limiting criteria is
applied to frames sent to the control plane, in order to avoid
overwhelming it under adverse conditions such as a Denial of Service
attack.

O: Also, a caution
   must be used such that only link local multicasts and broadcast IP
  packets are sent to control plane.

O: The multicast RA and RS Ethernet frames are replicated to using the
Send Multicast Replication Tree as described in section 6.3.

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
