Ipv6 relay / IPv6-PD ::/64

Im trying to get my ipv6 going.
I get my my Ipv6 trough 6rd (Telia Sweden)

This is what i got so far.

Protocol: IPv6-over-IPv4 (6rd)
Prefix Delegated: 2001:2002:d9d7:XXXX::/64
Address: 2001:2002:d9d7:XXXX::1/32
Gateway: ::d9d1:e4a6

Is there any additional serttings i need for wan6/lab (lan) ?
I happily supply more config/info ab the system.

Openwrt 21.02 / TP-Link Archer C2600

config interface 'LAB'
        option proto 'static'
        option netmask ''
        option ipaddr ''
        option device 'eth1.40'
config dhcp 'wan6'
        option interface 'wan6'
        option master '1'
        option ra 'relay'
        list ra_flags 'none'
        option dhcpv6 'relay'
        option ndp 'relay'
config dhcp 'LAB'
        option start '100'
        option leasetime '12h'
        option limit '150'
        option interface 'LAB'
        option ra 'relay'
        list ra_flags 'none'
        option dhcpv6 'relay'
        option ndp 'relay'

The instructions for 6rd are here.
Lab is missing the ip6assign option for sure. Also since you have a delegated prefix I don't see the need for doing relay on the dhcp settings.
