Title : BGP Custom Decision Process
Authors : Alvaro Retana

Filename : draft-ietf-idr-custom-decision-07.txt
Pages : 11

Abstract:
The BGP specification describes a Decision Process for selecting the
best route. This process uses a series of steps, made up of path
attributes and other values, to first determine the Degree of
Preference of a route and later as tie breakers. While existing
mechanisms may achieve some of the same results described in this
document, they can only do so through extensive configuration such as
matching communities to explicit policy and/or route preference
configurations present on each BGP speaker within their
administrative domain (autonomous system). Implementing some
specific fine grained policies through such mechanisms is cumbersome,
if even possible.
This document defines a new Extended Community, called the Cost
Community, which may be used as part of the Decision Process. The
end result is a local Custom Decision Process.
