RA's are generated by the HNCP router, so the generation could take the routing table into account (put prefixes WITH routes in preferred places). If the routing protocol would export the "distance" to the destination in form of the routing table metric value, the RA generation could even make sure that the "closest" gateway is always the preferred one. So we can manipulate the published RAs in a way that the hosts will take normally one the HNCP router prefers?
