[afnog] XLAT646 deployment

Sun Jul 4 21:32:38 UTC 2021

I'm not sure if vCPE have progressed in real deployment in African ISPs, I've the impression that didn't worked in the rest of the world.

It is true that you could have the CLAT in the vCPE VM (I did that many times for testing and training purposes).

The problem I see with vCPEs strategy is that for IPv6 you need to have a switch at the customer premises, able to support layer-3 IPv6 functions, in order to provide /64s in each customer VLAN, SSID, etc., etc. When you mix that with WiFi, it gets more and more complex, so I don't think it is actualy a good think.

Also, in those cases, part of the advantage of the IPv6-only with IPv4aaS (such as 464XLAT) is lost, even if you provide private IPv4 addresses to the customer, because you still ned to have IPv4 support in the last mile WAN link, so not too much sense.

    This is a great opportunity for vCPE's. There was big talk about them as 
    far back as 2011, but they only really became practical around 2017.

    For me, I'd likely focus on that if I had to deploy a significantly more 
    capable CPE in 2021. The problem you have is when some FNO's use Layer 3 
    for backhaul, in lieu of Layer 2, which can complicate vCPE deployments 
    for operators who don't own their own Access infrastructure.

    Mark.
