routeros LTE 接口获取 IPv6 地址问题

[xiaofami]

运行 routeros 7.14.3 （ X86 ）的一台工控机上安装了电信手机卡和华为 me909s-821 模块，开机后 LTE 接口自动识别并获取到了 IPv4 地址，但是尝试通过 DHCPv6 Client 获取 IPv6 地址没有成功。执行 AT 命令进行查询：

[admin@MikroTik] /interface/lte> at-chat lte1 input="AT^NDISSTATQRY?"          
  output: ^NDISSTATQRY: 1,,,"IPV4",1,,,"IPV6"
          OK

[admin@MikroTik] /interface/lte> at-chat lte1 input="AT^DHCPV6?"
  output: ^DHCPV6: 240e:40c:8500:65cb:5a2c:80ff:1234:5678,::,::,::,240e:41:c000:ffff::,240e:41:c900:ffff::,150000000,150000000
          OK

看起来模块已经正确获取到了 IPv6 地址（后 8 位已编辑）和 DNS 。通过 routeros 日志抓取的部分信息如下：

routeros dhcp6-client 配置：

[admin@MikroTik] /interface/lte> /ipv6/dhcp-client/print detail
 1    interface=lte1 status=searching... duid="0x00030001021e101f0000" dhcp-server-v6=:: request=address add-default-route=yes default-route-distance=2 use-peer-dns=no use-interface-duid=yes dhcp-options="" pool-name="test" pool-prefix-length=64 prefix-hint=::/0 dhcp-options=""

恳请大佬指点~

数据卡的话不一定有 PD 地址池，普通地址应该是 SLAAC 的，你这 DHCPV6C 请求地址应该不行

[yyzh]

要调成透传.流量都没开 pd 的.

我看到过这样一篇文章，作者说 NDIS 模式下无法获取 ipv6 地址，设法使用 mdim 模式后成功在 openwrt 中得到 ipv6 地址： https://www.52nantong.net/?id=407

华为这个模块在 routeros 中貌似也是 NDIS 模式，不知有无关系
