this requires a full data fetch, not doable in dns. and, at the other end of the spectrum, for any dynamic lookup on receiving a bgp announcement, the data had best be already in the router. a full data set on an in-rack cache will go nuts on any significant bgp load. beyond that, you are in non-op space. randy
