PBR has this tendency to be brittle in the face of topology changes.
There are much better way to outbound load-balance between providers =
offering same or similar quality routes to the same destination.
multi-AS multipath will do that if the peers are on the same router. =
BGPaddpath can do it for you if the peers are spread across routers.
