Enabling IPv6 on owned equipment
I have the Orbi 970 (BE 33000/BE 95) and looking to enable IPv6. What I'm not clear on, and netgear asked me to confirm with my ISP, is what config setting to select. Options are as follows:
Auto Detect
Auto Config
6to4 tunnel
pass-through
fixed
DHCP
PPPoE
6rd

Thanks so much, I need to send you a 6 digit security code, would you prefer to receive that code by email or text?

Xfinity IPV6 is undocumented and I can't get any technical answers out of them either or actually get to any type of network engineer. But, I can get it to work.
It's not entirely DHCPv6(managed). It's definitely not SLAAC (stateless). It's actually DHCPv6 "assisted or managed other stateful". Translating to your options, I'd try Auto Detect as a first option. See what you get. If that doesn't work, try the Auto Config one. You could try the DHCP option if that doesn't work -- it might be IPV6 from an IPV4 DHCP request, but I'm not sure about what your product does.
The other options will not work.
There may be a bit more to it as well, and IPV6 has always been a bit goofy in my market location and I'm not familiar with your product. It's also going to depend on how advanced your internal networking is.
You may have to specify the delegation prefix. Make that /64. If you "hint" for something else, it's probably not going to work. RA flags if you have them "Do not wait for RA". Also "Do not Allow PD/Address release" -- what that does is NOT drop a lease before a rebind. That way, if you can't contact the server upstream during a rebind, or you get a timeout, your internal routing won't be messed up during that time. (Xfinity is buggy).
If you have to setup a dhcpv6 server inside, use a /64 prefix. Set an arbitrary range -- something like ::1000 to ::2000. I use ravd to provide DNS servers I specify, but depending on how yours works, you make have to enter some IPV6 DNS servers to pass out someplace else.
Hope that's a start.
