Document: draft-ietf-idr-bgp-identifier-13.txt

Review Date: April 19, 2011

Summary: This draft is basically ready for publication, but has nits that should be fixed before publication.

This is a short draft that extends BGP to remove the requirement for use
of IPv4 addresses as BGP identifiers, and specifies the scope of uniqueness
for the resulting BGP identifiers as AS-wide.

Major issues: None

Minor issues: None

Nits/editorial comments:

This draft is missing an "Updates:" header to indicate what RFCs it updates.
I believe it updates at least RFC 4271.

The Acknowledgements section refers to IPv6-only networks as a rationale for
these changes to BGP.  Please add a couple of sentences to section 1 to
explain why IPv6-only networks are a motivation for these changes.

At the end of Section 3 - please remove the word "proposed" from the first
line of the following (as the changes will no longer be "proposed" when
the draft is published as an RFC):

   Therefore it is concluded that the revisions proposed in this
   document do not introduce any backward compatibility issue with the
   current usage of the BGP Identifier.

In Section 4, Security Considerations:

   This extension to BGP does not change the underlying security issues.

I suggest changing that sentence to the following two sentences:

   This extension to BGP does not introduce new security considerations.
   BGP security considerations are discussed in [RFC4271].

idnits 2.12.09 found some minor formatting problems (# lines/page, absence of
form feeds) that do not require a new version of the draft.

Thanks,
--David
