  Perhaps the thing you are looking for is SIR - the SDN Internet Router

  TLDR; use pmacct to grab top N ASN speakers and install them into the FIB. Rinse and repeat.

  Alternatively filter out anything not from ARIN. Conveniently fits into 250k:
  Prefixes being announced by ARIN Region ASes:                    238331

  Should you want something that isn't quite so bleeding edge beta, perhaps pick up a used Arista 7050QX? It's about 
the same as a CRS317 and holds 144k routes.
