我在 ubuntu 18.04 中设置了 2 个设备的结合。
看起来 bond0 正在启动并且我可以 ping 它，但是物理接口也从我的 DHCP 服务器获得了一个 IP 地址。
接口 enp3s0 和 bond0 的 IP 地址在同一范围内，这会导致麻烦。
有什么想法我的配置有什么问题吗？
我的 netplan 配置：
network:
version: 2
renderer: networkd
ethernets:
enp2s0:
dhcp4: false
dhcp6: false
enp3s0:
dhcp4: false
dhcp6: false
bonds:
bond0:
interfaces:
- enp2s0
- enp3s0
parameters:
mode: 0
addresses: [192.168.88.8/24]
gateway4: 192.168.88.1
nameservers:
search: [lan]
addresses: [127.0.0.1, 192.168.88.1]
应用配置后，设备上的 IP 地址如下所示：
bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST> mtu 1500
