The commercially available implementations do not work as you
described and fortunately do not carry that (or really, any) risk.

On platforms where the number of FIB entries is limited, but the
prefix length doesn't affect that limit (classic TCAM), it is possible
to combine adjacent entries (e.g. /24s) with the same FEC (next-hop)
into fewer entries.  This is probably what most people think of as
"FIB compression".  Maybe it's used somewhere, maybe it's not.

It's also possible to suppress the installation into the FIB of routes
when the prefix in question falls completely within a covering prefix
with the same FEC.  Doing so is computationally inexpensive, useful on
almost any FIB lookup structure, and significantly helpful (on the
order of 2x) on even very-well-connected routers.  This is implemented
by Arista in the feature that Yang linked to with the URL containing
"fib-compression", but the actual command is better named: "ip fib
compression redundant-specifics filter"

Also, on the B'com Jericho chip (used by the Arista 7500R/7280R and
Cisco NCS 5502/5508), there is a longest-prefix match (LPM) table and
a seperate, much larger, exact-match (LEM) table, both of which can be
used for IP forwarding.  (The LPM is sort of like TCAM but not exactly
-- for now, just consider it a limited resource in the same way as
TCAM has been historically.)  Neither of these can independently hold
the global table.  It is possible to optimize the use of these
resources by installing certain prefix lengths into LEM to preserve
LPM space.  It is also possible to do the reverse, expanding mid-sized
prefixes that would otherwise end up in LPM into multiple LEM entries,
to reduce the number of LPM entries needed -- basically creating an
optimum balance.  That is essentially the other Yang feature that was
linked.

As also mentioned, all of this works as advertised with basically no
limitations.  It's been running at Netflix (my employer) for years.

Current production "switch" chips, e.g. Jericho2, contain
significantly more LPM than is needed to hold the global table, and
can be paired with additional off-board memory (B'com calls this KBP)
for futureproofing or VRF scale needs.  You can buy either option
depending on your needs (e.g. the Arista 7280R3 is available in a "K"
and non-"K" model) .  The aforementioned LEM/LPM feature was a useful
bridge into this world of bigger tables in cheaper chips, but it's not
needed in new hardware.

James's original question was about using cheaper L3 devices.  At this
point, for new installs, even if you're limited to buying used gear,
you have options that don't involve any config gymnastics.

This is in fact how it works now at NANOG.  As John points out, the
decision is left up to the submitter, but almost all talks are webcast
and recorded.  (Historically, the security track has not been
recorded.)

Anyone is welcome to submit talks, including tracks, for
consideration, and to make this choice as submitter.  In this case,
the track moderator believes that it's better that the the talk to not
be recorded and so we are honoring that request.

Aside from the security track and one other submission, the remainder
of the 3-day program will be available for viewing and recorded.

Re: Anyone using Arista 7280R as edge router?

2017-04-17 Thread Ryan Woolley 
Yes, we (Netflix) have the Arista 7500R and 7280R widely deployed as edge
routers.  We're a few months away from shutting down the few remaining MXs
and ASRs in our CDN.

There was a thread from about a year ago that you might check out:
https://mailman.nanog.org/pipermail/nanog/2016-April/085472.html

Since then, route table growth hasn't changed appreciably.  Also, Arista
has added some features (notably route-map subroutine support and
default-deny) that improve BGP policy functionality.

If your use case allows you to use a default for those routes not heard via
your direct peers, there are options to increase the functional scale (and
thus to stretch the lifespan beyond ~4 years).  In addition to filtering,
there's support for selective route download, which will allow you to keep
a full RIB with a more limited FIB.

Regards,
Ryan

Just to be clear, this isn't (to my knowledge) something that Arista is
doing and so the risk described doesn't affect the products that were
discussed on that thread.

Peter, I'd point you to https://labs.apnic.net/?p=767 for more historical
detail and a table with some (recent) predictions.  The summary is that the
rate is mostly linear at around 10% per year and even 1MM routes lasts
quite comfortably beyond 5 years at the current growth rate.  I am not
particularly worried about the table growth rate (or Moore's law) changing
dramatically.

With respect to the utilization of the hardware, our setup is basically the
same as Lincoln's scenario #1 and so utilization looks about the same, on
both platforms.

Re: Arista Routing Solutions

2016-04-26 Thread Ryan Woolley 
While the QFX in general is similar to Jericho-based platforms, I think the
QFX10002 is perhaps not an ideal comparison.  At 100G, there is a
significant density penalty on that platform, as you can use all 36 ports
at 40G, but only 12 ports at 100G.

BGP convergence in the newer EOS releases is indeed very, very fast.

Re: Arista Routing Solutions

2016-04-26 Thread Ryan Woolley 
IOS-XR on ASR 9k and Junos on MX.

For our use case, there's no longer anything limiting as compared to those
platforms.  BGP policy is perhaps not as rich as you might be used to if
your experience is with the sort of routers traditionally marketed to
service providers, but I'm sure that will get better, and it's probably
irrelevant if your policy is fairly static.

You are correct that we do collect a lot of flow data, both via sflow and
Netflow.  We've been able to do everything we need with Arista's sflow
implementation.

We (Netflix) have been deploying the previous gen (7500E) as edge routers
for about two years in high traffic, low route count applications in our
CDN, and have been working with Arista for almost as long to improve route
scale so that we could turn off all our traditional routers.

The features that enable full routes on Jericho are running in our
production network today and we also have the 7500R and 7280R working with
full tables.

I can't speak to MPLS, but for our use case (all L3, very high-density
10/40/100G, BGP, IS-IS and light QoS), it's working well.

So, yes, I'd say those two products are quite viable and competitive
options in the edge router space.
