Wait so is it NOT supported to run IPv6 if one does NOT have Sonic provided router?

Basically the ONT connects directly into customer's firewall in this scenario

Thanks

Define "supported".

You are certainly welcome to use IPv6 with your own router, however our support is not equipped to help with problems that arise from differing protocol implementations on those devices.

The platform upstream of Sonic's fiber platform cannot support a router that does stateful address assignment (DHCPv6) by sending two separate Solicit messages for IA_NA and IA_PD assignments using DUID Type 2 or DUID Type 3 generation. This is a very specific restriction that most routers will not run into or can work around.

In this particular case, it seems this is a perfect storm for Meraki which, from what I've gathered, cannot change the DUID Type, cannot request ONLY IA_NA or IA_PD, and cannot combine the two requests into a single Solicit.
