[afnog] XLAT646 deployment

[JORDI PALET MARTINEZ]

Mikrotik is a good hardware, and cheap, however it is terrible for IPv6. Many problems and even mistakes, they confuse even RFCs ... it is very bad. I offered them helping even for free, no response.

However, most of the Mikrotik devices (low-mid-end) are just the same as low cost CPEs that you can buy in Aliexpress/Alibaba (such as those based on Mediatek), they even support OpenWRT. There are a few Ubiquity that also support that.

I just acquired 1 pcs of the CRS309 (8 x 10G SFP+ and 1 UTP Gig) and 2 pcs of the CRS305 (4 x 10G SFP+ and 1 UTP Gig) for my 10 Gig setup ... I was planing to use SwitchOS ... however the management interface doesn't support IPv6. How come, in year 2021???? So even now I've done the setup with IPv4-only management, I'm considering either swithing to RouterOS or finding if I can customize OpenWRT for them ...

Unfortunately, even if I tried to find equivalent devices to the CRS309 (150 euros) and the CRS305 (70 euros), price was not convenient. There is a new TP-Link close to the CRS309, but not yet available ... and I was not lucky to find those products from China.

So Mikrotik NO WAY, unless you will run only pure dual-stack ...

And if you decide to go for your own OpenWRT version, you are paving the way for future updates that you may offer to the customers and not depend anymore on concrete CPE vendors ... in addition to have a much cheaper CPE, which can be even more powerful.

SoC vendor (basically one of Mediatek, Broadcom, Qualcomm, Realtek, and Marvell) makes a chip set and a reference design. CPE vendors use the reference design and select if they one to have "n" number of ports, USBs, other interfaces, and design a "case". Sometimes, even the same product is being sold with a different case or same case/different label. They use the SDK from the SoC vendor (most of them based in fact in OpenWRT), or use directly OpenWRT. Done.

You can make a pilot with 10 employees and buy just 10 units. Of course, if you start mass deployment, you want to save some dollars and price will go down a little bit if you buy 100 or 1000 units, but the major savings will be in the shipping and customs costs.

It allows NAT offloading and that means that the CLAT is not noticed (anyway, typically only 1% of the traffic goes thru the CLAT), and can provide 2Gpbs of IPv4/IPv6 routing. Mediatek is very good because they provide open SDKs, which other vendors don't do (so it makes very difficult to work with Open Source ...).

This offer is extremely low cost, something like 20 USD or 1 USD per month for 2 years, etc. In fact this cover the full cost of the CPE and shipping to the customer!

    > What many operators don't realize is that with 464XLAT, your IPv4 traffic going thru the NAT64 will be 15-20% only and going down every year. This depends on the % of end-users vs enterprises. End users consume "more" IPv6-enbled services (social networks, NetFlix, Youtube, etc.). And when you have less and less NAT64 traffic, it means:
    > 1) Lower cost for your NAT64 boxes (even if it can be extremely low cost if you use racked servers with Jool or other open source alternatives).
    > 2) Lower number of IPv4 public addresses, so you could transfer them.

    If I had the cash, I'd pick up Mikrotik and bring them into the 21st 
    century :-).

    Mark.
