在 Ubuntu 22.04 上配置 VLAN

我尝试在一个物理接口上配置 2 个 VLAN ens33。并ens34用于访问互联网，但我无法从其他主机 ping 通虚拟机。虚拟机网络适配器位于 192.168.100.0/22 网络中。

这/etc/netplan/00-installer-config.yaml：

  ethernets:
    ens33:
      dhcp4: true
    ens34:
      dhcp4: true
  version: 2
  vlans:
    ens33.100:
      id: 100
      link: ens33
      addresses:
      - 192.168.100.70/24
    ens33.101:
      id: 101
      link: ens33
      addresses:
      - 192.168.101.70/24

这ip addr：

支持802.1q：

root@gateway:~# lsmod | grep 8021q
8021q                  36864  0
garp                   20480  1 8021q
mrp                    20480  1 8021q

并且两个虚拟机之间的流量未标记，主机 192.168.100.70 不回复 ARP 消息。交通

你能帮我找出问题所在吗？
