Hi Melchior

I read the two drafts rev 1 split into two separate drafts.  Looks good.

Let me know what you think of adding the use cases to the draft that I
mentioned in my rebuttal as to the context of the clipping of routes over
the maximum use case with logging.   Also this gives the operator
flexibility to disconnect, or log without disconnect of session, or clip at
the maximum without disconnect.

This 3rd option is important to operators to avoid an outage from
disconnect.

IDR WG

Please comment on the feedback context I have given on the clipping with
logging at the maximum prefix.

Kind Regards

Gyan
