[Kea-users] kea-dhcp6, radvd and GUA via SLAAC and ULA via DHCPv6

[Bastard Operator from Hell aka Django]

HI!

I'm really starting to despair of my sanity! Either I'm really getting 
too old for all this shit or those who have put their heads together 
with the RDCs around SLAAC and DHCPv6 have really consumed the most 
blatant dope!

Why?

Okay, I'll tell you. I've already had to find out the hard way that a 
client doesn't send two DHCPDISCOVER messages for announced GUA and ULA 
prefixes.

As an alternative, I then thought to myself, well, then let the radvd in 
its router announce advertisement messages for the GUA prefix SLAAC and 
refer to a DHCPv6 for the assignment of the ULA, which then assigns 
these statically on the basis of the DUID. Well, that's the theory and 
my reasoning, BUT: For DHCP, the AdvManagedFlag must be set to "on" and 
AdvAutonomouse to "off". For SLAAC, both values are the other way 
around. But now I have the problem that the parameter AdvManagedFlag in 
radvd.conf is defined for the interface and AdvAutonomous for the 
prefix, and defining the same interface eth1 twice fails with a radvd -c 
with an error. :/

Now the question arises, how can I configure the radvd so that the GUA 
can be assigned via SLAAC but the ULA statically via DHCPv6? Or how on 
earth do I get static ULA from kea-dhcp6 and GUAs via SLAAC? It can't be 
impossible what I'm trying to do.

I'm at my wit's end and I'm enjoying the best Scottish whiskey or 
Mexican tequila ...
