There may be a few more places to go searching. I am not saying you will find anything, but worth looking into, assuming Mikrotik won't help. :)

Check out what various SD-WAN vendors have to offer. Now, SD-WAN has about 46 definitions, as many as vendors (surviving vendors that is), but underneath all of them, it is some sort of box with a CPU, a semi-smart NIC with a bunch of ports and routing stack that happens to support L2 transport and can overlay it on top of any WAN transport, including regular IP underlay that can run on these fiber paths. The one of note is Versa. Besides BGP and overlaying, you may even get a useful multi-layer control plane out of it, which under the hood of all marketing definitions is all the things you are familiar with. And data plane that can actually do 10G.

Check out some of the Broadcom Qumran half-ru switches. Something like that:

There are a few other vendors besides Dell and Dell OS does have your basic P2P VXLAN and EVPN as VXLAN control plane. There are a few others including open source options. But you are using these small half-ru Broadcom Qumran and Trident reference designs.

And finally as you go on that search, you can always build your own. All you need is $100-200 mini-pc, Linux on it, some form of optimized forwarder and open source routing stack.

There are people out there who supposedly did that with Raspberry Pis and used Linksys routers. Not that you should do it, but shows that there are options and don't count on 10G!

Not sure how much of "CPE" it needs to be, but for example the whole Cisco Catalyst 9K product line (including the smaller C9300 switches) support the whole EVPN/VXLAN stack).
A similar set of products exist on the Arista side (e.g. 7xx switches) as well as Juniper EX4400 products...

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 & cheaper 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?

Reply here or privately, whatever floats your boat – any pointers appreciated!
