Comcast native ipv6 for network devices.

johnpoz,
Reach out in the Comcast forums on dslreports.com. It looks like they've set up DHCPv6 without RA. Just checking though, you've got a DOCSIS3 modem, right?
we use RAs + stateful DHCPv6. IPv6 auto-configuration is not supported.

Yup SB6120, and have PM out to netdog on that site, he responded already once - but seems I only game him the CMTS-MAC, when he needed the CM-MAC? So now I have sent him everything I could see from the modem with any sort of mac in it ;)
6120 is good to go, CMMAC or account # sent privately both work.
-
so I heard back from netdog

The CMTS your on supports IPv6 and I can see leases going out to other customers on the DHCP server.but I responded back to him that not seeing any RAs and no default route.
you should be learning the default route from the RAs sent by my CMTS.

That sure and the hell does not seem like a fix to me.. When it was working from pfsense, my clients were not working for starters.
A better fix would be to just go back to my tunnel ;)
And is it really common practice for my gateway to be linklocal? Then why give my interface a global address?? Shouldn't I have a global gateway address to match up with my /128?
I just do not get why they can not just freaking hand out the gateway via dhcp??
this would be a step backwards no?
-
I am aware that dhcpv6 does not hand out gateway! Just ranting here - don't understand why it was removed, why not leave it as an option?
Its not a fix, because setting a static gateway like that – that might change is not a good idea! If it was my network and knew it wasn't going to change then sure. But I have no idea what comcast might do next week.
Plugging a box directly into my modem is a great idea, because what I can tell you is not seeing any RA's for sure currently.
[jjmb] I also co-chair the IETF dhcwg, there is talk about adding this option. This is being heavily debated and even if it becomes available it does not mean people will use it.

Thanks for joining the forum, John. Much appreciate having your feedback and expertise shared here.
For those who don't know, that's John Brzozowski. Chief Architect, IPv6 and Distinguished Engineer at Comcast. Also a chair/co-chair of some major IPv6 working groups, a true authority on the subject.

hehe - that is awesome, but I think he need a little work on his forum use.
he has his comments inside the quote markers - at first glance it looked like he was just quoting without making any comments ;)

Dang kids and their forums these days… ;D Forums made me feel old back when we opened this site and I was 25 at the time. I edited his posts to properly quote.

Forums make you feel old? ;) You remember the old FIDOnet?
That use to be the sweetsuff when you could get a reply from someone in Japan in less than 24 yours..

Hey John,
When are you guys planning on rolling IPv6 out to Business Class customers? I've been dying to implement IPv6 at work haha. We have a SMCD3G-CCR modem, which doesn't appear to be certified for IPv6 yet on your mydeviceinfo site.
Thanks,
Derek
