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]
