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。对于 ipv4，我会使用arp命令。但我想解析知道 ipv6 地址的硬件地址。我读过 ipv6 有国家发展计划协议替换ARP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，我不确定安装一些软件包是否可以带来它。所以我想知道是否有什么方法可以检查ipv6的MAC表？也许我可以只是cat一些文件？
编辑：我安装了ip与管理器打包opkg，所以现在我可以使用ip -6 neigh show，但我仍然想知道是否可以使用 获得相同的信息cat somefile？
答案1
您可以使用安装 ndpmon 包：
