So it'll still do A=1 style addressing (EUI64, > privacy extension addressing etc)? Will it perform DAD?
from my memory: yes to all of those, for common desktop OS (Win, Linux, Max OS-X). When we did the lab testing for this one (https://www.ernw.de/download/ERNW_Whitepaper_IPv6_RAs_RDNSS_DHCPv6_Conflicting_Parameters.pdf) we played a bit with the L-flag as well, so the L=0 + A=1 scenario occurred. I don't remember any case where the things you mention did not happen. We still have that lab infrastructure so we can repeat (some of) the tests with L=1 (and without DHCPv6). Let me know if you (or the group) is interested; we can assign a student to the task.
