Router Selection

Guest · Posted: Wed Apr 19, 2006 7:22 pm Post subject: Router Selection

Hello All,

It's been a few years since I have selected a large router
(7500 vintage). This network is a star configuration with hundreds
of router (some 1721s) and routers from other vendors as well.

I'll need
1) gig ethernet ( 2 Gig E. ports would be nice.)

2) (1-3) 45MBPS interfaces for Frame relay

3) serial port for a gprs/ppp dial-up modem for secondary admin access.

4) ability to handle lots of video packets (H.264) from hundreds of
fractional and T1 frame circuits, across multiple interfaces.

5) redundant processors and power supplies

6) NO end-of-life models...

7) possible need to encrypt all packets on the network between the routers,
so support for AES between heterogenous (various models of different
vendors) routers would be keen. If I cannot get this, I might have
to use a Linux router with cards from Sangoma or other Linux friendly
router vendors.

8) VoIP which is not related to the streaming video, might be
added later, but it will not be a cisco centric solution,
probably some version of SIP.

The end-of-life issues are a bit clouded. I see the 7200 family
is at the end of line, but, then 7206VXR does not seem to be
at the end of life. I like the 7603, but, I'm not certain I need
that much iron, unless there are compelling reasons for a 76xx model.
I'd like to have at least 1 slot (2 card ports) empty after I get
this router configured.

I'd like input from users of these and similar routers as to what
models/cards/price/performance experiences you have and your
recommendations.

I've used many higher end routers (7500, 7200, etc), but not many of
the newer models (I currently use the 7206VXRs is the newest I've
worked on). But if you're looking at purchasing some new equipment,
I'd go with the latest hardware, which is what it sounds like you're
wanting to do.

If it were me, in my research attempts, I'd probably start by using
Cisco's hardware compatibility matrix, combined with the Software ad
visor. You'd include all the technologies and physical connections
you'd need, and see first off what routers support all that in one box.
Then research each of the higher end models you're looking for, and
figure out the range that will support your needs (based on pps
[processing power], maximum aggregate throughput it can route, etc).
Once you discover your range (the lowest model that will work, and the
highest model that will work (this would be based on price), then
you'll just have to narrow it down at that point.

Once you've got an idea of what you're looking for, then I'd also call
Cisco's pre sales support and discuss it with them and get an idea of
possible pro's and conns to the various models.

This should help get you started. If I get some time, I may do a bit
of this research as well and post it if I find out anything.

Look at the GSR...they'll be supported for quite some time to come.
Expensive but robust and scalable.
Avoid 7500 - early 90's architecture!
7206VXR with high-end NPE can just do what you want but (from memory)
no redundant processors. They are also getting old...
Not sure what a 7600 can do.
