绑定 NIC 和 VLAN 且网桥的 Netplan 无法正常工作

我遇到了 netplan 问题。配置如下。Bond 似乎正在工作，但我无法连接到在 Bond 上桥接的网络 VLAN128 (br128)。在服务器升级到 20.04 之前，硬件和 Bond 都可以正常工作（之前不是通过 netplan 实现的）。如果我只使用一个以太网 NIC，即移动 VLAN128 到单个非 Bonded NIC，它也可以正常工作。

绑定接口上缺少的是所有路由，这看起来很奇怪，因为单个 NIC 上会自动生成路由。所以我不知道发生了什么。有人知道我错过了什么吗？

为了解决您的第二个问题，您应该能够通过设置明确设置 mac 地址macaddress，例如将其设置为与您的物理接口相同的 MAC：

[...]
      br88:
        macaddress:       DE:AD:BE:EF:CA:FE
        dhcp4:            yes
        dhcp4-overrides:
          hostname:       defiant
        interfaces:
          - vlan88
      br94:
        macaddress:       DE:AD:BE:EF:CA:FE
        dhcp4:            yes
        dhcp4-overrides:
          hostname:       defiant94
        interfaces:
          - vlan94
[...]
