netplan -两个接口

Question

我想在netplan的一个配置文件中设置两个接口。

目前我正在使用这个：

  network:
  version: 2
  renderer: networkd
  ethernets:
          ens18:
                dhcp4: no
                dhcp6: no
                addresses: [1.2.3.4/32]
                gateway4: 1.2.3.254
                nameservers:
                        search: [domain.tld]
                        addresses: [123.456.789.101]
                routes:
                - to: 1.2.3.254/32
                  via: 0.0.0.0
                  scope: link
          ens19:
                dhcp4: true

没有第二个接口(ens19)，它可以正常工作。在添加了第二个接口(ens19)后，系统在启动时遇到了一些问题。但是当系统出现后，第二个接口就正常工作了。

我做错什么了？

提前谢谢。

请添加此配置：

network:
    renderer: networkd
    ethernets:
        ens18:
            addresses: [1.2.3.4/24]
            gateway4: 1.2.3.254
            dhcp4: no
            dhcp6: no
            nameservers:
                    search: [domain.tld]
                    addresses: [123.456.789.101]
            routes:
            - to: 1.2.3.254/32
              via: 0.0.0.0
              scope: link
        ens19:
            dhcp4: true
            dhcp6: no
    version: 2

不需要重新启动

sudo netplan --debug apply

请粘贴此文件的输出

您确定您的DHCP中需要大约1700万主机吗？

10.0.0.0/8是一个大型(非常大的网络)，也许这就是减慢它的原因。但是，您可以这样做：

ens19:
        dhcp4: true
        dhcp6: true
        optional: true

这应该可以弥补缓慢的启动，或者改变(如果可以的话)您的网络大小。
