Re: Metro Ethernet: 2821 vs. 2921 router

I hate to rain on the Cisco parade here, but for the price, the chart (»/speak/slidesh···cm91dGVy) kamikatze See Profile posted is pathetic—and reeks of Cisco overselling. I like Cisco as much as the next guy, but you might want to SERIOUSLY consider looking at open source here. MOST MODERN PC-CLASS MACHINES with GigE NICs will OUTPERFORM almost EVERY ROUTER on that chart. Yes, these routers can do things open source can’t (and the same is true vice versa), but if all you need is some commodity firewalling and QoS, you’d be foolish not to evaluate open source as well. Hell, even the ASA devices run Linux at their core. At the very high end, NO PC can match ASIC driven hardware, but you are NOWHERE near there.

Sometimes going with Cisco is akin to murdering money.

is the chart 100% accurate? depends on your definition of accurate.

i would assume that these routers/engines are being tested under "ideal" conditions - no firewall, no nat, large packet size, no qos. under those conditions, i'm sure you hit the throughput numbers before the pps numbers. however, if you're passing a lot of rtp for voip in the network, obviously, you're going to hit pps limits before throughput.

is the cost of a 2821 worth it? depends on what you're going to do with it and how much you value your time. with your open source solutions, you could saturate a 100meg metro-e link and provide qos and firewall and such. however, if you're looking for a solution to a "one-off" scenario, you could be searching/working for hours or even days. cisco has a support base and plenty of people who have "been there and done that". i also like the flexibility of the isr series for gateway routers because of their versatility - i can make it an edge firewall, provide qos, terminate remote access vpns, and have it function as a call manager and unity server - a branch in a box.

now, i'm not discrediting one solution over the other - they are both valid (however you must realise that i'm biased in one direction - an exercise i'll leave for the reader to determine which way). part of being a successful network engineer/architect is knowing how and where you should fight your battles and with what gear. i'm not against running juniper, force10, or other manufacturers of gear as long as you select the right box for the job.

A bit late to the party, but we ended up going with a 2921. Seems to work out just fine. No complaints.

should crack it open and take pics of the hardware for kamikatze See Profile

I will say that the 2921 was roughly the same cost as the 2821 when we were ordering it. I think it's simply a no-brainer considering the 2921 can handle more bandwidth.

Even a show version/platform/diag is great!

Great machine - maybe a bit overkill for your application but excellent bang for the buck

Indeed it is a great machine, an overkill perhaps, but it gets the job done and leaves plenty of room for bandwidth upgrades going forward.

Now our only bottleneck is every subscribers personal router. I think the 20-35 mbps symmetrical bandwidth is too much for some people's equipment. Never thought I'd see this as being a problem, it's a happy/sad feeling.

We bought a pair of these and are very happy thus far.

We went through our ISP for everything. 2821 was priced at $3200, 2921 came in @ just under $3000. Newer router was cheaper, go figure...

No actual hardware identifiers... well nuts to that Cisco!
Any chance of getting pics of the internals?
