Got a question, so a 7513MX2/8 fairly new model within Cisco still ONLY supports 256MB of Ram. So lets track the trends and try to predict when Cisco will force everyone into a new BGP master router? The issue as well remains that with 256MB RAM and RSP8 in a 7513 on a default free network having 200+ peering sessions and 100K+ routes consumes well over 128MB of RAM and the processor load spikes into the 80%-100% when major instabilites happen. Continue with uncontrolled growth to the Internet routing table and you will soon be replacing it with something bigger (but that would help the stock pricing rise aobe $12 share, huh).

Any Taiwan-made PC can swallow much more. The limit is not clear but is certainly far away from us.I want to you to put a couple of channelized DS-3s, an ATM OC12c, and a POS OC48c to your backbone plus all the BGP peers you can sign up at AADS on a PC.Yes but you can't put all that on the "loaded" 7200s you mentioned either. I think the point he was trying to make was not that we should use PCs as routers, but that routers we *do* use are at least as powerful as Taiwan PCs (for this application). When Sprint was filtering there was a demonstrable need based on the 64meg limit that mainstream routers had for memory at the time. I do not see that there is any such physical limitation today and I guarentee that the router vendors (all two of them) have learned the lesson of not including enough address lines on the equipment to allow for easy memory upgrades. -vb
