Re: Metro Ethernet: 2821 vs. 2921 router

MetroE might be code for internet connection with ethernet access handoff to client. You would need a MLS capable of NAT in that case, or a separate firewall.

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

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.

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

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.

What was the street price?

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