Ubuntu 18.04 netplan多VLAN多网桥配置

网络配置

要点： 仅主网桥配置网关，其他不要配置，可以设置默认路由

以下是一个可行的配置方案

network:
  version: 2
  renderer: networkd
  ethernets:
    enp6s0:
      dhcp4: false
      dhcp6: false

      id: 10
      link: enp6s0
    vlan20:
      accept-ra: no
      id: 20
      link: enp6s0
    vlan30:
      accept-ra: no
      id: 30
      link: enp6s0
