ipv6 client issue

Hi,

i want the configure the Mikrotik router for IPv6 as DHCPv6 client.

From the log we become every time the message:

  • Server support for prefix delegation is not enabled. sorry buddy
  • bad status in advertise: no prefix (6)

I receive a DUID from the DSL modem.

i have configure the DHCPv6 client and his pool as follow
/ipv6 pool add name=“ipv6-local” prefix=“a000::/64” prefix-length=64
/ipv6 dhcp-client interface=“WAN-port” pool-name=“ipv6-local” pool-prefix-length=64

the information we having from my isp is:
Lan sub net = 2a02:1810:cc13:a000::/64

what going wrong?
how we must configure the client dhcp and his pool?
