I'm curious on the details:


Do you give the client 64 bit using RA (with the A and L bit cleared), 64 bit 
using DHCPv6, then force the traffic through the default since on-link is not set?

Has there been any test if modern operating systems honor this?

(I've seen some firewalls doing this, not sure it was by design, they changed 
the default in later code)

Do you only use link-local on the customer port, and use a L3 CPE & DHCP-PD?

Always a learning experience reading Nanog....
