我在安装新版 ubuntu 服务器时遇到了问题。我使用 systemd-networkd 配置了一个绑定网络，虽然可以正常工作，但每隔几个小时它就会停止工作。
10-bond0.netdev
[NetDev]
Name=bond0
Kind=bond
[Bond]
Mode=802.3ad
TransmitHashPolicy=layer3+4
10.bond0.网络
[Match]

IgnoreCarrierLoss=3s
DNSSEC=allow-downgrade

CriticalConnection=true

20-enp2.网络

Bond=bond0
PrimarySlave=true
当它关闭时，对 1.1.1.1 的 ping 操作会超时。
拨打电话systemctl restart systemd-networkd即可解决问题，直到下次发生故障为止。

仅介绍一下丢失的承运人。

我尝试了几乎所有能想到的方法，但这种情况还是不断发生。我不知道下一步该做什么或如何修复它。有人能帮忙吗？
