I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors. Document editors and WG chairs should treat
these comments just like any other last call comments.


This document refers to [RFC6371] and [RFC6941] for detailed security
discussions. I have no problem with that. However I have two comments:

1/ It says:
   "Implementations therefore are required to offer security mechanisms
    for OAM.  Deployments are strongly advised to use such mechanisms."
These sentences do not use the RFC2119 key words. Is that deliberate?

2/ I really have problems understanding the following claim:
   "Mixing of per-node and per-interface OAM on a single node is not
   advised as OAM message leakage could be the result."
Can you be more explicit in the I-D? It's important since it's probably not
discussed in [RFC6371] and [RFC6941].

Minor comments:

** MEP is used without being defined.
