Technical Summary

The base BGP specification defined the BGP Identifier as "a valid
IPv4 host address".  This is problematic in some contexts
including IPv6-only networks.  This document relaxes the
definition to be a 4-octet unsigned, non-zero integer, and relaxes
the "uniqueness" requirement so that only AS-wide uniqueness of
the BGP Identifiers is required. These revisions to the base BGP
specification do not introduce any backward compatibility issue.

Working Group Summary

 The document has received extensive WG review and is generally
 non-controversial and clearly needed.


Document Quality

There are several existing implementations, and furthermore the
document makes no on-the-wire protocol changes and is backward
compatible.  The document does not use RFC 2119 language but I
don't view this as a problem. 

Personnel

John Scudder is the Document Shepherd for this document.
Stewart Bryant is the Responsible Area Director.
