The IESG has approved the following document: - 'AS-wide Unique BGP Identifier for BGP-4' (draft-ietf-idr-bgp-identifier-14.txt) as a Proposed Standard This document is the product of the Inter-Domain Routing Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-idr-bgp-identifier/ 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. RFC Editor Note At the end of the abstract please add: This document updates RFC 4271. ========
