Internet Standard, Informational, Experimental, or Historic)?  

Proposed standard 

Why is this the proper type of RFC? replaces standard RFC8203 
and obsoletes RFC8203.  Updates RFC 4486. 
Is this type of RFC indicated in the title page header?
yes - it indicates standard, obsoletes RFC8203, and updates RFC4486. 

(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up. Recent
examples can be found in the "Action" announcements for approved
documents. The approval announcement contains the following sections:

Technical Summary

   This document enhances the BGP Cease NOTIFICATION message
   "Administrative Shutdown" and "Administrative Reset" subcodes for
   operators to transmit a short freeform message to describe why a BGP
   session was shutdown or reset.  This document updates RFC 4486 and
   obsoletes RFC 8203 by defining an Extended BGP Administrative
   Shutdown Communication to improve communication using multibyte
   character sets.

Working Group Summary

  Was there anything in WG process that is worth noting? For 
  example, was there controversy about particular points or 
  were there decisions where the consensus was particularly 

  Support was given in IDR and grow (OPS BGP review)

Document Quality

  Are there existing implementations of the protocol? 
  3 implementation of the RFC.  Implementation report at:

  Have a  significant number of vendors indicated their plan to 
  implement the specification? 

  No additional implementation reports, but wide-spread 
  operator demands so it is likely more implementations will appear. 

   Are there any reviewers that 
  merit special mention as having done a thorough review, 
  e.g., one that resulted in important changes or a 
  conclusion that the document had no substantive issues?

   If  there was a MIB Doctor, Media Type or other expert review, 
  what was its course (briefly)? 
    No MIB or Yand Doctor or other specific expert review.
