How to configure the odhcpd to make sure i can use the ipv6 on lan? Thank you very much! I'm sorry, my English is not good.

For IPv6 connectivity on the LAN you need to delegate a prefix to the lan. In order to delegate a prefix you need to receive a prefix on the WAN; above output shows no prefix is received on the wan6 interface as the ipv6-prefix field is empty alas no IPv6 connectivity on the lan. Either the upstream DHCPv6 server on the wan network is not configured to give an IPv6 prefix or the DHCPv6 client is not requesting a prefix.

First of all, thank you very much for your answer. As you see, my school internet server doesn't provide a prefix for DHCPv6 client. Is there any way i can use to use the ipv6 on lan? My router is lenovo newifi mini. I can only use Barrier Breaker or CC, which ipv6 address can only get from odhcpd? I tried ipv6 NAT and Radvd, my pc got a ipv6 address, but can not ping ipv6.google.com. Can you give me some instructions? Thanks again!
