联网:4个单独的子网默认路由一致性警告？

Question

刚刚安装的Ubuntu和我的一个网卡端口不工作，也没有平它的IP - eno2。

在安装过程中配置的Netplan：

运行了这个

echo 101 eno1-route >>/etc/iproute2/rt_tables
echo 102 eno2-route >>/etc/iproute2/rt_tables
echo 103 eno3-route >>/etc/iproute2/rt_tables
echo 104 eno4-route >>/etc/iproute2/rt_tables

rc.local

#!/bin/bash

在应用netplan时获取此错误。

** (generate:5742): WARNING **: 05:13:22.079: Problem encountered while validating default route consistency.Please set up multiple routing tables and use `routing-policy` instead.
Error: Conflicting default route declarations for IPv4 (table: main, metric: default), first declared in eno2 but also in eno4

重启后，所有的IPs -包括IPv4和IPv6 --似乎都是可点击的。怎么一回事？我已经有不同的路由表了。冲突的默认路由声明！？

ip route list返回

Answer 1

您有不同的路由表，但是当您使用gateway4和gateway6速记时，这并不会使用那些路由表。要获得所需的结果，您需要将默认路由拼写为routes:，而不是https://netplan.io/reference/#default-routes中所描述的。

Answer 2

“在应用netplan时获取此错误。

** (生成:5742)：警告**：05:13:22.079:验证默认路由时遇到的问题，consistency.Please设置多个路由表并使用routing-policy。错误: IPv4的冲突默认路由声明(表: main，度量: default)，首先在eno2中声明，但也在eno4中声明“

检查/etc/netplan文件夹中有多个YAML配置文件。

如果有多个文件，则清除单个文件可能会解决冲突。

我收到了这条错误消息，发现一个99- netplan文件与标准的00-installer-config.yaml文件相冲突。

删除99文件解决了问题。
