Rolf,
 
    Earlier you had the following comments (our response embedded):
 
Section 2:

MPLS-

This proposed change could be interpretted to mean very nearly the
opposite of what was

intended.  But the current wording could use improvement.  We spent some
time figuring 

out what we feel is an appropriate compromise and we propose to change
the applicable

text to read:

 

"For the management interface to the management system, an MPLS-TP NE
MAY

actively support more than one management protocol in any given
deployment. For

example, an MPLS-TP NE may use one protocol for configuration and
another for

monitoring. The protocols to be supported are at the discretion of the
operator."


Section 4:

We propose to add "including"  as you suggest. 

 

Section 5.3.2:

>

Done.

 

Section 5.3.4:

> 

> Quote: The MPLS-TP ME SHOULD

>        report local (environmental) alarms

> 

> I assume you mean NE above and not ME as e.g. defined in

Uh, yeah.  Changed to "NE"...

  

Section 10 not needed I assume.

 

Section 10 is IANA considerations, and is a required section.  We
propose at this time

to add text indicating that there is no IANA action required by this
document.

Yes, your comments were helpful and we deeply appreciate your effort and
willingness

to provide them.  Thanks!!
