Autonomous-System-Wide Unique BGP Identifier for BGP-4
RFC 6286, “Autonomous-System-Wide Unique BGP Identifier for BGP-4”, is a Proposed Standard document published in June 2011 by E. Chen, J. Yuan. It updates RFC 4271. The canonical text is published by the RFC Editor.
Abstract
To accommodate situations where the current requirements for the BGP Identifier are not met, this document relaxes the definition of the BGP Identifier to be a 4-octet, unsigned, non-zero integer and relaxes the "uniqueness" requirement so that only Autonomous-System-wide (AS-wide) uniqueness of the BGP Identifiers is required. These revisions to the base BGP specification do not introduce any backward compatibility issues. This document updates RFC 4271. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
