[AusNOG] Commercially available CPE that supports 464XLAT

Sun Feb 24 11:36:36 EST 2019

Hi Craig,

It will be good if you name the concrete model. I was not aware of that and I'm very interested.

Responding to Damian, in this article I summarize the panel that I organized a couple of years ago in APNIC, there are also videos.

https://blog.apnic.net/2017/11/09/ce-vendors-share-thoughts-ipv6-support/

The vendors present can offer firmware versions with the support, but at the time being is not the standard one. Ask your contacts in those vendors to escalate, because in some countries, I know by personal experience, they aren't getting the info ...

Hopefully this will change soon, as this document:
https://datatracker.ietf.org/doc/draft-ietf-v6ops-transition-ipv4aas/

Is already approved and in the RFC editor queue to turn it into an RFC (I guess is a matter of few weeks).

I strongly suggest everyone to point their vendors to this document and include it in RFQs, etc.

If you want to test with a good open source implementation, either the NAT64 or the CLAT, I use Jool in my trainings.

Regards,
Jordi

    I think the newer Huawei CPE can (not the 658 )

    > Does anyone know of a commercially available CPE router that supports 464XLAT (i.e. the 464CLAT part)? From what I have found only openwrt seems to support it. This is surprising given that the technology has been around for a long time - T Mobile in the US have used it to allow their network to become IPv6 only over 4 years ago. There is a reasonably mature open source implementation of it etc etc.

The great thing about 464XLAT over (say) DSLite is that you can remove IPv4 completely from the core network and you end up with just one IPv4 nat between the customers home device (XBox etc) and the internet - which most applications can handle OK.

I am not sure what manufacturer they used - Sagemcom? - I think they had to get them to produce a special build. Is there a copy of his presentation anywhere?
