Hi,
          i'm using odhcp6c as dhcpv6 client on my router and not able to get address assigned to eth0 interface even though the serve has replied back. Below is my configuration
config interface loopback
        option ifname   lo
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0

config interface lan
        option type bridge
        option proto static
        option ipaddr 192.168.1.254
        option netmask 255.255.255.0
        option ifname 'eth1 eth2 eth3'
        option ip6assign '64'
        option macaddr '00:10:18:00:00:07'
        option is_lan '1'

config interface wan
        option ifname 'eth0'
        option type anywan
        option macaddr '00:10:18:00:00:08'
        option reqopts '43 66 67 128 132 224 225 226'
        option reqprefix '64'
        option reqaddress 'try'
        option proto 'dhcp'

config interface 'wan6'
        option proto 'dhcpv6'
        option ifname '@wan'
        option reqaddress 'try'
        option reqprefix 'auto'

Error log :

Maybe you didn't get a prefix delegated via DHCPv6, but only a single address that the router can use the WAN interface.

I would suggest that you back up your configuration, and do a "reset to defaults". I have found the default config works pretty well with DHCPv6-PD.

The discussion might have continued from here.
