링크 로컬 주소를 사용하는 크로스오버 케이블(스위치나 DHCP 서버 없음)을 사용하여 임베디드 장치(systemd-networkd 실행)를 PC(Ubuntu, Win, OS X)에 연결하고 싶습니다.
DHCP를 제공하는 네트워크를 통해 연결하면 모든 것이 잘 작동하고 주소가 *.localDHCP IP에 연결되며 avahi 브라우저가 네트워크에서 내 장치를 감지할 수 있습니다.
GUI를 사용하여 네트워크 구성을 변경하는 경우 지금은 Ubuntu와의 교차 연결만 시도했습니다.자동(DHCP)도착하다로컬에서만 링크ip a내 임베디드 장치와 PC 모두 LL IP를 갖고 있으며 LL IP(직렬 인터페이스를 통해 연결할 때 얻은)를 사용하여 내 PC에서 장치를 ping 할 수 있지만 Cann'이라는 *.local이름을 사용하여 주소를 지정할 수 없습니다. 아무것도 avahi-browser찾을 수 없습니다 .
내 사용 사례를 설명하는 예제를 온라인에서 찾을 수 없습니다. 이는 이상합니다.제로 구성이러한 사용 사례를 처리하도록 설계되었습니다.
내 임베디드 장치(ARMhf의 Ubuntu 16.04.01)에 대한 IP 설정은 다음과 같습니다.

이것은 내 유선 네트워크 설정입니다.

또한 다음 두 가지 옵션을 추가하려고 시도했지만 도움이 되지 않았습니다.
