Hello, all.
I’m having difficulty finding vendors, never mind products, that fit
my need.
We have a small but growing number of L2 (bridged) customers that have
diverse fiber paths available, and, naturally, want to make use of them.
We have a solution for this: we extend the edge of our EVPN VXLAN
fabric right to the customer premise. The customer-prem device needs
4x10G SFP+ cages (2 redundant paths, plus LAG to customer), and the
switches we currently use, Arista 7020Rs, are quite expensive if I’m
deploying one one per customer. (Nice switches, but overkill here – I
don’t need 40/100G, and I don’t need 24 SFP+ ports. And they still
take forever to ship.)
We use RFC7438 §6.3 “vlan-aware-bundle” mode, not §6.1 “vlan-based”
mode, which limits our choices somewhat. I might be willing to
entertain spinning up a separate VXLAN mesh using RFC7438 §6.1
(“vlan-based”) and static VTEPs if it saves me a lot of pain.
However, I’m having trouble finding small & cheap*/er/* 1U (or even
desktop/wallmount) devices that have 4 SFP+ cages, and can do VXLAN,
in the first place.
Who even makes CPE gear with SFP+ ports? (Other than Mikrotik
CRS309-1G-8S+IN / CRS317-1G-16S+RM, which are nice, but our policy
requires vendor support contracts, so… no-go.)
Vendors? Model#s, if you happen to know any?
You will have trouble finding such a device at the price you need
because it is atypical to have your customer's CPE as part of your
Metro-E backbone.
Our sales people have asked for this more times than I can remember. We
have continued to refuse for a reason.
They've angled their query to extend our u-PE devices into the customer
site, to which they can attach their CPE. We have refused that too,
because most customer's do not allow 3rd party fibre x-connects into
their site (for example, some country's embassy, a stock exchange
building, a bank, e.t.c.), never mind the fact that most customer sites
are not fitted with 24/7/365 availability and security. And we continue
to refuse.
My advice - don't do it. But it sounds like you want to, so...
Mark.
