RE: Cisco Router best for full BGP on a sub 5K bidget 7500 7200 or other vendor ?

I was surprised by the similarities between the 7507 and 7513. Why EOL
the one device that has a pleasing form factor ? There are MANY
providers who would be quite happy with ~ 600 mbps? That's a lot of
billings...

It's the 7505 that's EOLed. Possibly because it doesn't sell well
enough, I don't know. For an ISP environment it has a significant
problem in not supporting redundant powersupplies.

I think there are long-term contracts with certain Big Customers (tm)
that preclude EOLing the 7507 and the 7513, else they would be EOL as
well. Just a guess though.

The AGS+ was manufactured in small quantities for many years after
commercial sales for all intents and purposes ceased, to support these
same customers.

How much common components / manufacturing did TGS share with AGS?

Reading this thread, it looks to me like everybody's discussing the "one
true router" for doing BGP, without regard to any other requirements that
may exist in this situation.

Being able to take a full BGP table in a Cisco is simply a matter of
having enough memory. We're using 1760s as the current generation of PCH
route collectors, and they're working quite nicely. For anybody who only
wants to route a few Mb/s of traffic with a fairly simple network
topology, just about anything with enough interfaces and at least 192 MB
of RAM should work. As the network topology gets more complex or the
traffic volumes increase, it becomes a matter of finding the router that
fits the topology and can handle the traffic volume, while BGP capability
becomes a minor concern.

First, figure out whether you want a router or a switch: Are you doing
anything that requires a router to isolate different switch networks
(hooking 20 or 30 or more switches together can cause some intersting
issues...)? Do you have the sorts of flows that make a switch that
routes advantageous? Does the ability to assign ports to lots of
arbitrary VLAN interfaces without having to trunk the router to an
external switch appeal to you?

Then figure out how much traffic you want the router to be able to handle.
Average load probably isn't nearly as much of a concern as peak load.
It's also worth considering what sorts of traffic surges or DOS attacks
you want to be able to survive, since those may push your traffic volumes
well above your usual peaks.

At that point, there's still a bunch of research to do, in terms of what
meets your requirements and what's available within your budget, but it
makes it much easier to say whether a given platform that's available for
the right price will work.

Certainly not the bent steel (those TGSes were an instant hernia in a
box!), and I think the appliques were actually different assemblies,
not just funky passthroughs. And of course, power line filtering was
different on the TGS.

Aside from that, though... the guts were pretty darned similar,
probably identical. I've certainly swapped boards between [AT]GS
systems with impunity (we weren't worried about maintaining our
certification!).

Yours for router necromancy and GS2-R...

Having seen the Juniper router which has PICs sawn down the middle of the PCBs
to fit and homemade faceplates, nothing much surprises me.. :slight_smile:
