	Your draft was published first shortly before
the MIB doctor meeting in Atlanta.

 >> yes, but did not given a chance to present. 

> (2) I do not know what change that you are referring here. 

	You asked us to add the ifIndex to the sessionDown/up
notifications in the LDP MIB, which being a non-major change,
we all agreed could be made.

>> Yes, thank you.

	Then I suggest you to re-read the meeting minutes.
There were definite agreements made, as I mentioned.
Specifically, the chair of the meeting suggested 
(and we all agreed to this) that the purpose of the meeting
was to get the existing MIBs into shape. This did NOT include
any enhancements (many of which were proposed in your ID).
Instead, it was noted that these would be put off as
future work.

>> OK. So, one year has passed by and how much more "put off" that we
can afford to wait. I would suggest that we put those enhancements
proposal on the table again for managability sake (its about time). As
you already know, we, as a service provider, need those capabilities to
manage our MPLS network. 

	--Tom
