在netplan中复制一组ip命令

Question

我最近从16.04升级到Ubuntu 18.04和我试图找出如何让我ip route和ip rule命令，我习惯把中/etc/network/interfaces下netplan工作。

这些是我试图重现的命令，我以前运行过/etc/network/interfaces：

sudo ip rule add table 129 from 192.168.1.160
sudo ip route add table 129 to 204.8.230.0/24 dev enp0s3
sudo ip route add table 129 to 192.168.1.0/24 dev enp0s3
sudo ip route add table 129 default via 192.168.1.1

这是我第一次通过 netplan 配置/etc/netplan/01-netcfg.yaml：

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: yes
      routes:
        - from: 192.168.1.160
          to: 204.8.230.0/24
          via: 192.168.1.1
        - from: 192.168.1.160
          to: 192.168.1.0/24
          via: 192.168.1.1

但是，重新启动后，这些路由不会显示在ip route输出中。我如何让这些路线坚持下去？

请注意，我还尝试/usr/lib/networkd-dispatcher/routable.d根据我找到的一些文档将这些命令放入脚本中，但这似乎也不起作用。

编辑：我越来越近了。这是新的配置，但现在的问题是，虽然该表显示在 中ip rule，但它ip route show table 129是空的：

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: yes
      routing-policy:
        - from: 192.168.1.160
          table: 129
      routes:
        - to: 204.8.230.0/24
          via: 192.168.1.1
          table: 129
        - to: 192.168.1.0/24
          via: 192.168.1.1
          table: 129
        - to: 0.0.0.0/0
          via: 192.168.1.1
          table: 129

我在 netplan 版本 0.36.1

我想到了。问题是 systemd-networkd 试图在网络启动之前设置路由，但失败了。修复是on-link: True在路线上：

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s3:
      dhcp4: yes
      routing-policy:
        - from: 192.168.1.160
          table: 129
      routes:
        - to: 204.8.230.0/24
          via: 192.168.1.1
          table: 129
          on-link: True
        - to: 192.168.1.0/24
          via: 192.168.1.1
          table: 129
          on-link: True
        - to: 0.0.0.0/0
          via: 192.168.1.1
          table: 129
          on-link: True
