我想使用链接本地地址使用交叉电缆（无交换机或 DHCP 服务器）将嵌入式设备（运行 systemd-networkd）连接到 PC（Ubuntu、Win、OS X）。
当我通过提供 DHCP 的网络进行连接时，一切正常，地址*.local链接到 DHCP IP，并且 avahi 浏览器能够在网络上检测到我的设备。
我现在只尝试了与 Ubuntu 的交叉连接，如果我使用 GUI 更改网络配置自动（DHCP）到仅链接本地我的嵌入式设备和 PC 都获得了 LL IP，并且我能够使用 LL IP（ip a通过串行接口连接时获得）从我的 PC 对设备执行 ping 操作，但我无法使用该*.local名称对其进行寻址，也avahi-browser无法找到任何东西。
我无法在网上找到讨论我的用例的示例，这很奇怪，因为零配置旨在处理此类用例。
这是我的嵌入式设备（ARMhf 上的 Ubuntu 16.04.01）的 IP 设置：

我还尝试添加接下来的两个选项，但没有帮助：
MulticastDNS=yes
IPv4LLRoute=yes
