Apples and oranges, probably, but Digital's routers in Palo Alto (a
pair of AlphaStation 200s, each with 128MB of memory and a pair of
FDDI boards) have a kernel routing table size of 8735 Kbytes (9178
Kbytes peak). The virtual size of the gated process is 27.9Mbytes. We
get full routing tables from Alternet and BBN Planet, and however many
AS paths CIX is supplying. From a gated dump I took on March 28th, I
count 6517 AS paths. As of a couple minutes ago, we have 34662
BGP-supplied routes in our routing table.
