BGP Extensions for Routing Policy Distribution (RPD)
draft-ietf-idr-rpd-04
Abstract
It is hard to adjust traffic and optimize traffic paths on a
traditional IP network from time to time through manual
configurations. It is desirable to have an automatic mechanism for
setting up routing policies, which adjust traffic and optimize
traffic paths automatically. This document describes BGP Extensions
for Routing Policy Distribution (BGP RPD) to support this.

1. Introduction
It is difficult to optimize traffic paths on a traditional IP network
because of:
o Heavy configuration and error prone. Traffic can only be adjusted
device by device. All routers that the traffic traverses need to
