我有两台 ubuntu 机器，每台都有两个物理网卡。我试图在其中两台机器之间创建一个私有网络，将一个节点的网卡与另一个节点的网卡连接起来。
在节点 1 中运行
是否配置

现在，当我尝试从节点 1 执行 ping 操作时enp5s0接口 169.254.9.9 没有收到任何数据包，当我尝试从节点 2 dpdk 接口 ping 时dpdk0IP 地址为 169.254.9.10，我收到输出：网络不可达。
请注意，在我的两个节点上，我都使用以下命令启用了数据包转发：
sudo sysctl -w net.ipv4.ip_forward=1
我将非常感激任何有关我做错事情的提示。我猜根据 ARP 表判断，这些接口根本不存在条目，但我不知道如何在路由表中设置这些条目，以便能够在两个节点之间进行 ping 操作。
