This document proposes a solution for BGP route reflectors to facilitate the application of closest exit point policy (hot potato routing) without requiring further state or any new features to be placed on the RR clients. This solution is primarily applicable in deployments using centralized route reflectors. The solution relies upon all route reflectors learning all paths which are eligible for consideration for hot potato routing. Best path selection is performed in each route reflector based on a configured virtual location in the IGP. The location can be the same for all clients or different per peer/update group or per neighbour.
