I was chatting with someone the other day and we were trying to build a complete list of all units which can handle full routing tables 1 year from now, assuming current 4k/month growth (nevermind de- aggregation) Juniper M/T-series units could handle 600k before, now 1mil with I- chip upgrade? Juniper MX-series units are always 1mil Cisco 6500/7600 with SUP720-3BXL handles 1mil routes Force10 E300/600/1200 with dual-cam line cards handle 512k routes Force10 E600/1200 with Exascale (quad-cam) line cards handle 1mil routes Is there anything I'm forgetting here? And if you already have one of these units, the upgrades are: Juniper M-series units can replace the FPIC card to get new I-chip? ...if I understand it, no other cards need replaced Cisco 6500/7600 you replace SUP32 or SUP720 with SUP720-3BXL ...if I understand it, no other cards need replaced? (note that this disagrees with my understanding of how their FIB/CEF works so I'm curious about this) Force10 you replace every single line card, since the entire chassis is limited to the smallest CAM size available. -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness
