We have had customer try this configuration and go to malloc hell. 128mb is the minimum for a full view these days. A Riverstone RS8000 or a Cisco 3640 will handle several full views nicely with 128mb. Remember the 3640 won't go above 128mb, though. A 3660 or a SSR makes a nice CPE box if you need 256mb.
Unless Cisco have changed something, a 3640 can only take 64Mb of memory max. You'd need a 3660 for 128Mb. You can get away with a Cisco 3640 for full BGP, but it does depend on the cards you have installed. NM-1A-T3 is a memory hog for example, but if you've only got NM-2E2Ws you're probably OK. You might also need to tweak iomem, but later IOS releases do this for you. 11.2 might be a better choice for BGP-speaking 3640s are the memory requirements are lower. -- Ryan O'Connell - <ryan () complicity co uk> - http://www.complicity.co.uk I'm not losing my mind, no I'm not changing my lines, I'm just learning new things with the passage of time
