Hi Blake,
I’m not sure what sort of speeds you think Linux limits out at, but I
believe you might be surprised at how much throughput you can get. We
generally blow the doors off of the VXRs and down.
There are two different ways of getting hardware redundancy. One is
with a massively expensive single box, like the Cisco. The other is to set up
redundant hardware…which is particularly good in a BGP application. You can
have a relatively inexpensive router on each circuit, set up iBGP and VRRP
between the boxes, and BGP between the peers. That way, if you lose anything,
all the in and outbound traffic fails to the other unit(s). This also allows
for geographic separation of the routers. If you can bridge between the
routers, you can have them in completely different locations…thus keeping your
network running if something really nasty happens.
I can’t speak for the other companies, but ImageStream has been
handling BGP for around 10 years. We use Quagga currently and we’ve found it
to be very stable, as our customers on-list have attested. It’s one of our top
applications.

Hardware redundancy, wire speed packet forwarding, support for more
Interface types, and more widely tested& stable software.
I'll use a MikroTik, Linux, or BSD box as an aggregation router any day;
terminate some VLANs, act as an MPLS CE, perform QoS marking, and participate in an
OSPF area. Probably nothing more. The level of hardware redundancy& wire-speed
forwarding isn't there for my needs.
If you're just knocking IOS, I realize it isn't the wave of the future.
Cisco does too& has developed IOS XR.
Linux, MikroTik, and I'm sure Vyatta& ImageStream are great platforms.
They compete well with Cisco in some areas...others not so much. Use what's
appropriate.

What specifically do you think is superior in IOS (Unix-based
originally) to a hardened, purpose-built Linux distro (us, Mikrotik, Vyatta,
whatever)?

Tom,
I agree that Linux works very well as a router, but it still doesn't
compare to a dedicated hardware platform (like Cisco) that was built
from the ground up to do nothing but routing. We purchased a used Cisco
12008 router about 1.5 years ago off ebay. They are very, very cheap...
the only downside is they are BIG and require 240VAC. But it's way cool
to pull the CPU card while the router is moving 500Mbps of traffic and
have it not even miss a single ping (due to the redundant CPU card).
Same goes for the route fabric card. ;)
We use Mikrotik for our inside "core" router and this big Cisco for our
border router to our BGP upstreams. I have slept very well for the last
1.5 years knowing everything in the box is fully redundant (CPU, route,
power, etc.). :)

Imagestream and
Vyatta both use Quagga. Both are great choices for BGP routers.
I personally use Mandrake (Mandriva) Linux with a slew of custom
modifications that we have made, loaded on SuperMicro, and then use
latest
Quagga.
That has worked well for us, the last 5 years. (although, I dont
recommend
that to someone, until they are vastly familiar with their distro of
Linux.
Last thing you want to do is use your BGP router for a Guinee Pig
Science
project, rebooting it all the time to test script changes.) But once
you are
comfortable with your Distro, it works well.
There are a million arguements "for" and "against" Cisco versus Linux,
to be
used for the ISPs' average NOC/POP router/switch. I dont dispute any of
the
arguements. But one area where I believe Linux stands tall, is as a
CORE BGP
router. A core BGP router can be one of the more simplistic configured
routers because it only really needs to perform one function, BGP
routing to
its connected peers. For BGP there are two critical needs.... Fast
processors and Lots of RAM. In todays world there is no excuse to not
have
both of those. The problem with Cisco is that it lacks both, unless
you pay
big bucks. Linux on the other hand has an abundance of both, when
combined
with PC-Like hardware.
I laugh at my competitors, when they say, "oh no, BGP reset, had to
reload
BGP tables, now there is latency for like 3 minutes or compromised
routing
for that period" or "got a route problem, the small prefixes aren't in
my
tables". . On Linux, if you want to restart BGP, well thats like 1
second to
reload tables. And no need to drop any routes, unless you want to. You
could
have Full routes with like 30 peers from a single router, if you wanted
to.
You can load up Linux with like 32 NICs (qty8 4port GIG NICs) in a 2U
case,
if you want to, and dont even need a Switch. (Although new will cost you
about $430 per 4port PCI-E Gig NIC).

I still need to try a Vyatta system.
I loathe the idea of managing a *nix distro on a router (which is why we
use RouterOS now). Apparently I've had too much Tik-aid, because I had
completely forgotten about Vyatta and similar options.
I have a SuperMicro 5015A-H (Atom 330 dual-core) coming in tomorrow.
I'm going to try RouterOS and Vyatta and see how BGP responds on each
with a single feed. If anyone else has an x86-based distro they'd like
to see performance on, let me know.
And thanks for all the responses. The information has been very
helpful. Unfortunately, the conclusion I came to is "I have no idea
what I'm going to do." Cisco = $$$ and MikroTik = coin flip. Hopefully
Vyatta lands somewhere in the middle.
Thanks,
