A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Inter-Domain Routing Working Group of the IETF.

        Title           : BGP Custom Decision Process
        Authors         : Alvaro Retana
                          Russ White

   The BGP specification defines a Decision Process for installation of
   routes into the Loc-RIB.  This process takes into account an
   extensive series of path attributes, which can be manipulated to
   indicate preference for specific paths.  It is cumbersome (if at all
   possible) for the end user to define policies that will select, after
   partial comparison, a path based on subjective local (domain and/or
   node) criteria.

   This document defines a new Extended Community, called the Cost
   Community, which may be used in tie breaking during the best path
   selection process.  The end result is a local custom decision
