顺便贴出来当前生效的配置
```
/ipv6 dhcp-client
add add-default-route=yes allow-reconfigure=no check-gateway=none default-route-distance=1 default-route-tables=main dhcp-options="" dhcp-options="" disabled=no interface="China Telecom" pool-name=ipv6_pool pool-prefix-length=60 prefix-address-lists="" prefix-hint=::/0 request=prefix use-interface-duid=yes use-peer-dns=no validate-server-duid=no
```
以及日志(拿到的前缀我打了码)
```
