dhcp6 server not working with Linux client

Sat Nov 09, 2019 10:02 am

Whenever my Linux client attempts to request an IPv6 address via DHCP I get the following error:

nov/08 23:49:51 dhcp,debug,packet dhcp: recv server: lan fe80::2d9:d1ff:fef6:c438 -> ff02::1:2
nov/08 23:49:51 dhcp,debug,packet dhcp: type: solicit

nov/08 23:49:51 dhcp,debug,packet dhcp: -> elapsed_time: 655
nov/08 23:49:51 dhcp,debug dhcp: handling only prefix delegation, discarding..

Any idea what is going on?
My ISP provides a /56 though the dhcp client on the RB gets a /60. I use a couple of subnets for my internal LAN and WLAN networks.

pool:
0 lan-ipv6 2603:xxxx:yyyy:d001::/64 64
1 D wan-ipv6 2603:xxxx:yyyy:d0f0::/60 68 2d23h13m10s
2 wlan-ipv6 2603:xxxx:yyyy:d002::/64 64

dhcp-server:
0 lan lan-bridge lan-ipv6 255 3d
1 wireless wlan-bridge wlan-ipv6 255 3d

addresses:
0 G 2603:xxxx:yyyy:d001::/64 lan-ipv6 lan-bridge yes
1 G 2603:xxxx:yyyy:d002::/64 wlan-ipv6 wlan-bridge yes
2 DL fe80::zzzz:zzzz:zzzz:zzzz/64 wan0-vlan no
3 DL fe80::zzzz:zzzz:zzzz:zzzz/64 wan-bridge no
4 DG 2603:xxxx:yyyy:d000:66d1:54ff:feff:61cb/64 wan-bridge no

Running 6.45.7

Mikrotik dhcpv6 server only supports prefix delegation, you cannot use it for managing IP addresses. Use SLAAC if possible.
