Avoid BGP Best Path Transitions from One External to Another
RFC 5004, “Avoid BGP Best Path Transitions from One External to Another”, is a Proposed Standard document published in September 2007 by E. Chen, S. Sangli. The canonical text is published by the RFC Editor.
Abstract
In this document, we propose an extension to the BGP route selection rules that would avoid unnecessary best path transitions between external paths under certain conditions. The proposed extension would help the overall network stability, and more importantly, would eliminate certain BGP route oscillations in which more than one external path from one BGP speaker contributes to the churn. [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.
