我是用的自购的光猫和 Mikrotik hAP ax2 路由器，光猫是桥接的，用路由器拨号。位置在鹤沙航城。
昨天凌晨断网将近一分钟，我重置 PPPoE 密码之后重拨连上了（不知道是不是无效操作），重连之后公网 IPv4 变成了 58.37 网段，Active AC name 变成了 SH-SH-GD-VBASCP-1.NMAN.V6000，然后就发现拿不到 IPv6 前缀了。
IPv6 配置为
/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=::/60 \ request=prefix \ use-interface-duid=yes \ use-peer-dns=no \ validate-server-duid=no打开 dhcp, packet, debug 日志看到如下输出：
