为什么我在 bond0、en01 和 enp2s0 上有不同的 IP 地址？

  • 772

我根据这个网络计划在 Ubuntu 18.04 中为故障安全设置了网络绑定：

network:
    version: 2
    ethernets:
        eno1:
            dhcp4: no
        enp2s0:
            dhcp4: no
    bonds:
        bond0:
            addresses: [192.168.3.5/24]
            gateway4: 192.168.3.253
            nameservers:
                addresses: [208.67.222.222,208.67.220.220,8.8.8.8,8.8.4.4]
            dhcp4: no
            interfaces:
                - eno1
                - enp2s0
            parameters:
                mode: active-backup
                primary: eno1

现在，当我登录时，我得到：

IP address for enp2s0:  192.168.3.96
IP address for eno1:    192.168.3.96
IP address for bond0:   192.168.3.5

ifconfig 给了我（删节）：

bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST>  mtu 1500
        inet 192.168.3.5  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 xxx:a31d  prefixlen 64  scopeid 0x20<link>
        ether xxx:a3:1d  txqueuelen 1000  (Ethernet)

eno1: flags=6211<UP,BROADCAST,RUNNING,SLAVE,MULTICAST>  mtu 1500
        inet 192.168.3.96  netmask 255.255.255.0  broadcast 192.168.3.255
        ether xxx:a3:1d  txqueuelen 1000  (Ethernet)

enp2s0: flags=6211<UP,BROADCAST,RUNNING,SLAVE,MULTICAST>  mtu 1500
        inet 192.168.3.96  netmask 255.255.255.0  broadcast 192.168.3.255
        ether xxx:a3:1d  txqueuelen 1000  (Ethernet)

我敢肯定，在设置绑定之前，两个 MAC 之一以:a3:1c

我在设置绑定时是否犯了错误，或者这是预期的行为？

编辑

我不得不重新安装，这是安装程序为我的相同配置生成的文件，包括绑定：

network:
    bonds:
        bond0:
            addresses:
            - 192.168.3.5/24
            gateway4: 192.168.3.253
            interfaces:
            - eno1
            - enp2s0
            nameservers:
                addresses:
                - 8.8.8.8
                - 8.8.4.4
            parameters:
                mode: active-backup
    ethernets:
        eno1: {}
        enp2s0: {}
    version: 2

    小修改...注意缩进、间距和没有制表符...

    network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      optional: true
    enp2s0:
      optional: true
  bonds:
    bond0:
      interfaces: [en01, enp2s0]
      addresses: [192.168.3.5/24]
      gateway4: 192.168.3.253 # are you sure it's .253?
      nameservers:
        addresses: [208.67.222.222, 208.67.220.220, 8.8.8.8, 8.8.4.4]
      parameters:
        mode: active-backup
        primary: eno1

    sudo netplan --debug generate# 生成配置文件

    sudo netplan apply# 应用配置

    reboot#确保正常运行
