如何在知道 ipv6 addr w/o ip 命令的情况下解析 MAC？

Question

我在路由器上安装了 OpenWrt，我想获取连接到它的某些机器的 MAC 地址。使用 ipv4 我会使用arp命令。但是我想知道 ipv6 addr 来解析硬件地址。我已经读到 ipv6 有ndp协议替换arp并且查找 MAC 表的命令是ip -6 neigh show，但问题是我的 OpenWrt 中的 BusyBox 没有ip命令，我不确定安装某些软件包是否可以带来它。所以我想知道是否有任何方法可以检查ipv6的MAC表？也许我可以只是cat一些文件？

编辑：我用manager安装了ip包，opkg所以现在我可以使用了ip -6 neigh show，但我仍然想知道我是否可以使用 获得相同的信息cat somefile？
