This is certainly wonderful. But could be technically complex. Sending only local routes to local Mon'Pop shop is easy. But sending Mom'Pop routes to your local customers only is not easy. You would almost have to have a seperate routing policy for each local site to prevent local Mom'Pop shop routes from getting into other region's routers. Otherwise, these routes could turn up be BGP best routes, and when you deny them to your customers at other regions, you end up do not announce any Mom'Pop owned blocks and cut off linkage between your customers at other regions to Mom'Pop shop. Anyone has good/easy solutions to that?
