rib dumps

i am looking for date-stamped rib dumps going back years from a peering edge router that is fairly 'stable', i.e. multi-peer dfz but the number of peers changes infrequently. [ routeviews and ris do not meet the above description as they are not at all stable in the number of peers. ] [ your internal router which feeds off route reflectors does not meet the above description, as it is not peered externally to multiple peers. ] thanks! randy
