Received changes through RFC Editor sync (changed abstract to 'The purpose of this report is to document how the requirements for publication of a routing protocol as an Internet Draft Standard have been satisfied by Border Gateway Protocol version 4 (BGP-4).

This report satisfies the requirement for "the second report", as described in Section 6.0 of RFC 1264. In order to fulfill the requirement, this report augments RFC 1774 and summarizes the key features of BGP-4, as well as analyzes the protocol with respect to scaling and performance. This memo provides information for the Internet community.')

Re-review by Elwyn Davies, Gen-ART (following up on Lucy Lynch):


Hi.

I was asked to take a look at this doc, re-reviewing it after fixes relating to comments on -05 by Lucy Lynch.

Unfortunately the updates don't appear to have taken care of many of the formatting and boilerplate issues flagged by idnits.

There are still several over-long lines and hyphenations plus the URL for the list of I-Ds is still wrong.

Idnits output follows:

  Checking nits according to http://www.ietf.org/ID-Checklist.html:

    Checking conformance with RFC 3667/3668 boilerplate...
    the boilerplate looks good.

  Checking nits according to http://www.ietf.org/ietf/1id-guidelines.txt:

    The document seems to lack a 1id_guidelines paragraph about the list
    of current Internet-Drafts -- however, there's a paragraph with a
    matching beginning. Boilerplate error?

  (Expected a match on the following text:
    "The list of current Internet-Drafts can be accessed at
    http://www.ietf.org/1id-abstracts.html"

  ... but found this:
    "The list of current Internet-Drafts can be accessed at
    http://www.ietf.org/ietf/1id-abstracts.txt.")


  Miscellaneous warnings:

    None

Other matters relating to language:
===================================

Terminology:
There is a considerable amount of terminology in the document which is not defined either explicitly or by reference, notably BGP speaker, peer, EBGP

Some language improvements:
Section 1: s/Classless InterDomain/Classless Inter-Domain/ in line with title of [CIDR]

Section 2.1, para 1: s/network layer reachability information/Network Layer Reachability Information/

Section 2.2, para 1, last sentence: s/assist/assists/(also in para 2 last sentence), s/select/to select/

Section 2.2, para 2, last sentence: I don't think you can limit congestion to window limits:  How about 'The window limits used by TCP further assists BGP to constrain any congestion that might result from updates.'

Section 2.2: para 3: s/sent as a single Network Layer Reachability (NLRI)./sent in a single Network Layer Reachability Information (NLRI) attribute./

Section 2.3:
s/There may exist a temporary period where in a BGP peer may have
  separate incoming and outgoing connections resulting into two
  different BGP FSMs for a peer (instead of one). This can be resolved
  following BGP connection collision rules defined in the [BGP4]./

  There may be a short period during which a BGP peer may have
  separate incoming and outgoing connections resulting in the creation of two
  different BGP FSMs relating to a peer (instead of one). This can be resolved by
  following the BGP connection collision rules defined in the [BGP4] specification./

Section 2.3, para 3: s/Following are different states of BGP FSM for its peers:/The BGP FSM has the following states associated with each of its peers:/

Section 2.3, next to last para:
  s/different/a number of/,
  s/BGP FSM/the BGP FSM/,
  s/These BGP events are/Support of these BGP events is/,
  s/using an/as a result of/

Section 2.3, last para:
  s/Both,/Both/
  s/in details/in detail/

Section 4: Should be consistent in using either 'flapping' or 'oscillation'.  Flapping is normally used with routes.

Section 4: Is 'Ideally' the right word? ... Maybe either 'By default' or 'According to [BGP]'

Section 5:
  s/bound,/bounded,/
  s/loosing/losing/g
  s/clesrly/is clearly/

Section 6.1: s/,describes/, describes/

Section 6.1.1:
  s/announcments/announcements/
  s/During the periods/During periods/

Section 6.1.2:
  s/byte/octet/g
  s/(and ignoring/(ignoring/

Section 7, para 2:
  s/provided hundreds/provide hundreds/  [? really hundreds??]
  s/more and more/increasingly/

Section 7: s/nondeterminism/non-determinism/g

Section 8: s/we answer the question of which environments is BGP well suited/we identify the environments for which BGP is well suited/

Section 8, para 3: s/that allow/that allows/

Section 8, lata para: s/suitable/suited/

Section 10:
  s/exhanged/exchanged/
  s/guage/gauge/
  s/vulneribility/vulnerability/

Section 10: Need to expand the EBGP abbreviation.

Section 10: The reference to [SOBGP] is inconsistent with the list of refs [soBGP].

Also another couple of editorial nits:
(Throughout) There are multiple blank lines surrounding section headings and in some cases between paragraphs - a single blank line would save paper.
