Which router to buy?

From: John Oliver on 8 Nov 2006 13:48 We have a T1, and we're adding a second from the same provider to bond with the first. It's possible that, at some point, we might want to add a third. We have a PIX firewall on the inside that handles VPNs, NAT, etc. I don't think the router needs to do anything but handle raw connectivity. I'm having a tough time finding out what's the difference between 1800 series vs. 2800 series, or 2801 vs. 2810 vs. 2811 And then the 2600 series seems to still be sold... I thought they'd be pretty ancient, but if they'll do the job... -- * John Oliver http://www.john-oliver.net/ *

At a quick glance, if you want your T1 channelized you would need an NM- series, which would require a 2811 or upwards -- the 1800 series and the 2801 do not support NM modules. If you do not need your T1 channelized then one of the many WIC or VWICs might be appropriate; find the type you need, count the ports, count the slots you would need to support your target of 3 T1s, and that will tell you the minimum device to use. >And then the 2600 >series seems to still be sold...

The 1800 and 2800 series are much faster, but even so are only aimed at about 3 T1 (2821) or about 5 T1 (2851), if I recall the marketting literature. The router line rate performances would seem to suggest that they would support noticably more T1's, but the third party test report suggests the marketted target is about right.

Thanks, but... all of that info is part of my problem :-) There are 30,000,000 different things that these routers do or support, and I don't know what the heck most of them are :-) We're just using it for data T1s. 1.544 Mb/s Voice is on a separate T1, so no channelization. Looking at all that info is just overloading me... it doesn't come out and say "This router will let you install X WICs, and this one will let you install Y WICs" That should be all I need to know... we just want to buy it with two WICs and be able to add at least one more at some point in the future. We need one Ethernet coming out to go to the PIX and that's it. I don't care how much RAM, CPU, which IOS, etc. it has as long as two or three T1s can be connected and it can handle "converting" them to Ethernet. that's it... no fancy ACLs, no bizarro networking, no Token Ring or proprietary interfaces. Can I put three WICs in a 2801? Or do I need a 2811 or something else? I just can't tell from the mountains of information Cisco provides about these things :-) -- * John Oliver http://www.john-oliver.net/ * |
