Best Practices for Advertisement of Multiple Paths in BGP

BGP Add-Paths: 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 load balancing. Add-paths is currently being standardized...
