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. ]
