Asking purely out of 'curiosity' because a friend who works for an up-and-coming social network aggregator is needing to expand his network, starting to take on their own feeds, etc. They've acquired a couple of Catalyst 4948's on the advice from a network engineer that they'll take two full tables. Whilst this is indeed true, they wouldn't be able to *use* the full tables so I was just double-checking my information - thanks! Speaking from work-perspective, we've been using Linux + Quagga up until '07 when we acquired a 7600 series - they're bloody marvellous.. Deploying another 3 x 7600 series to completely obliterate Linux/BSD from our core routing layer in the next 1-2 months, hopping with excitement actually as they should arrive in 7-10 days :P show memory statistics [pruned a bit] Total(b) Used(b) Free(b) Processor 928148912 358931896 569217016 FIB TCAM usage: Total Used %Used 72 bits (IPv4, MPLS, EoM) 524288 246285 47% 144 bits (IP mcast, IPv6) 262144 1738 1% Seems that two feeds with ~240k routes and ~200k routes respectively plus some partial/peering use about 215MB (bgp process). _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
