Nah. There are lots of things you’ll need to know.

Does it use SLAAC on the WAN side or DHCPv6? How do I get a range for my lan then, DHCPv6 prefix-delegation? Or maybe it’s statically assigned somehow. Some carrier’s just use link-local ok the WAN, with no public v6 just RAs for the link-local, and a GUA block via IA_PD.

Regardless there are too many ways this is done, and this hampers adoption as it’s not just the “switch it on” operation you suggest.
