Hi John, The main thing you need to look at is not the number of DSL/PPP sessions but the aggregate traffic (Mbps) through the router. This will drive your decision.
Any idea on the amount of traffic you're expecting across your DSL sessions ? If you're looking at 3RU then you'd probably be better sticking with 7200. You could always go with 7201/7301 (both 1RU) if you're short on space and don't need anything more than a few GE ports. regards, Tony. ________________________________ From: John Elliot <[email protected]> To: cisco-nsp <[email protected]> Sent: Friday, 13 January 2012 2:07 PM Subject: Re: [c-nsp] LNS router options Thanks Hotmail - Ill resend to accommodate the (lack of) formatting.. Have a potential new pop that we are looking to terminate dsl tails(+MPLS,MPBGP, single Inet(full table), and some ethernet tails) - Have some space restrictions(RU) Looking for some "real life" experience with the following platforms(Or alternatives?) on how many dsl tails they can support: 2851 - Cisco stated performance: 220,00PPS (2RU) 2951 - Cisco stated performance: 580,000PPS (2RU) but assume quite $$? 3845 - Cisco stated performance: 500,00PPS (3RU?) 3925 - Cisco stated performance: 833,000PPS(3RU?) but assume quite $$? (NB would max out the ram on them for the bgp table) Initially we are looking at ~100 dsl tails, with growth to 150 in 6months....are we better off looking at the old faithful 7200?
