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 http://gregsowell.com/?p=5505 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. Jared
