Title : BGP Custom Decision Process
Author(s) : Alvaro Retana

Filename : draft-ietf-idr-custom-decision-00.txt
Pages : 8
Date : 2011-11-21
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
process.
