Ben,

The Dell options intrigue me. First question is who do you talk to at Dell
about their solutions as most sales guys just seem to know their laptop and
server lines?
How does Dell's pricing compare with Edge-Core. Considering most of the
hardware is the same Broadcom chipset, what are the reasons you went with
Dell over someone like Edge-Core or the other OEM's?
I have looked into   IPInfusion OcNOS and feature wise it looks nice, but
by the time you pay   IPInfusion OcNOS for the software and an OEM for the
hardware the costs adds up to a Cisco/Juniper equalivent model.

Dell seems interesting as I think they include an OS for free, but then you
can load   IPInfusion OcNOS or Cumulus or others onto it if that doesn't
meet your need. You mentioned  FTOS9. Doesn't Dell now have  OS10 version?

I've been testing IPInfusion OcNOS running on Dell Z9100 and S4048.  I've
run a couple of test cases using MPLS LDP signaled port based and VLAN
based VPWS (pseudowire / e-line / xconnect / Juniper CCC) and VPLS (e-lan)
over an OSPFv2 IGP.  It's working well between Dell/IPI to Dell/IPI boxes.
We have had issues with the VPLS between Dell/IPI to Juniper/JunOS where
the circuit will show up on the Juniper and down on the Dell.  If we clear
LDP session on the Dell, it comes back up right away.  This seems to be
similar to what Aaron is seeing in his multi-vendor environment.  The price
on the Dell hardware is really good.  The features included with OcNOS are
much better than FTOS9.  If you aren't partial to Dell, you can run OcNOS
on a variety of other whitebox switches, like EdgeCore.

I haven't tested MP-BGP and L3VPN or BFD yet, but that is supposedly
supported in OcNOS as well.

What is your budget?

I know on the low end many operators are using the
Huawei S6720S-26Q-EI-24S-AC. You can get these new for $2500 to $3500, and
the support all the features and port counts you requested. The also have
a
lifetime warranty that includes advanced replacement (10 days), TAC
support, and software support all for free if you buy through official
channels. It support MPLS, and also VXLAN.

Extreme seems to have some good options, but I doubt they are that low
cost.

For Juniper you need to look at the ACX series which is expensive. Like
the
ACX5048 which list price is $40k not that anyone pays list, and that's
before port licenses. The EX series does not have proper MPLS support.

Cisco has mutliple options, but mainly the NCS based on your port count I
think. Supposely the C3850 and C9500 now support MPLS? There is a new 16
port 10G version of the C9500. I haven't looked into Nexus switches. Does
Nexus support full MPLS?

HPE has some low cost options. In their FlexFabric and FlexNetwork lines
that support MPLS in Comware V7.

Who else are we missing? MPLS support really cuts down this list, but I
agree its a critical feature for most service providers.

Hello,

we're looking for some L3 switches to be used as distribution devices.
They should have all (at leaast 24) SFP+ ports 10G and at least a
couple of
upstream ports 40G capable, but what is most important, they should be
able
to run MPLS, EoMPLS and VPLS. Is there any device you would suggest us?
We
where thinking about NEXUS but I'm sure there are also others, even if
it
is not so easy to find them on the Internet.

Thank you in advance for your help .
