Add-Paths is a BGP enhancement that allows a BGP router to advertise
multiple distinct paths for the same prefix/NLRI. This provides a
number of potential benefits, including reduced routing churn, faster
convergence and better loadsharing.

This document provides recommendations to implementers of Add-Paths
so that network operators have the tools needed to address their
specific applications and to manage the scalability impact of Add-
Paths. A router implementing Add-Paths may learn many paths for a
prefix and must decide which of these to advertise to peers. This
document analyses different algorithms for making this selection and
provides recommendations based on the target application.
