직렬 네트워크 오류(CentOS 7)

내 서버에서 IPv6를 실행하려고 하는데 제대로 작동하지 않는 것 같습니다. 하지만 더 큰 문제가 있어 IPv6 네트워크 실행을 방해하는 것 같습니다. 오류 없이 네트워크를 다시 시작할 수도 없습니다. 편집: 방금 뭔가를 시도했으므로 하단의 업데이트를 참조하세요.

참조되는 것을 보았지만 /etc/sysconfig/network-scripts/route6-eth0인터페이스가 ens3다음과 같아서 편집 route6-eth0하고 변경했습니다.

2001:0df3:5c00:0552:0000:0000:0000:0001 dev eth0
default via 2001:0df3:5c00:0552:0000:0000:0000:0001

도착하다:

2001:0df3:5c00:0552:0000:0000:0000:0001 dev ens3
default via 2001:0df3:5c00:0552:0000:0000:0000:0001

그런 다음 실행했지만 mv /etc/sysconfig/network-scripts/route6-eth0 /etc/sysconfig/network-scripts/route6-ens3여전히 오류가 발생했습니다.

이것은 다음의 출력입니다 systemctl status network.service.
