Abstract:
   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.
