I have first experience with Ipv6 on mikrotik 5.11 in "client mode". It's horrible ...
I need accept router-advertisiments on routers. CPE doesn't have default route without RA (ospf is not applicable). It is linux problem, http://tldp.org/HOWTO/Linux+IPv6-HOWTO/ ... ipv6..html (if forwarding, accept ra is disabled). I need write access for this value ... may be in winbox, or CLI only.
how i find out DUID? In no way ... Only on DHCP server in log messages, or by studying tcpdump. Or at least that was in the manual method of DUID creation. In my RB1100AH is created from MAC address ether12 - why? Why not from first interface? Or last interface? Or not from routerboard serial number? Simply predictable way.
I need stateless configuration. IP address (and default route) for devices on LAN side from RA, DNS servers from stateless DHCP. Using statefull DHCP for this is unnecessary in most cases.
So take the prefix via DHCP-PD and assign to the LAN interface. And stateless DHCP server, of course.
But even if statefull configuration should be able to take the prefix /64 for client from PD and allocate him /64 too, from same segment. Why not?
Or receive eg. /62 from PD and asign four /64 segments on four idependent interface.
wan interface - accept RA (with default route).
lan interface - accept prefix from PD and using it as global address.
dhcp server - stateless configuration.
(P.S.: i apologize for my English).
