linux 多网卡同一个网络无法ping通

Question

基本上，我在同一个网络上有 2 个 NIC 的 Linux。第二个 NIC 除了 192.168.3.1 之外看不到任何东西

eno1 192.168.3.25
eno2 192.168.3.26

以下情况失败：
1. ping -I eno2 8.8.8.8 （或任何外部 IP）
2. ping -I eno1 192.168.3.26
3. ping -I eno2 192.168.3.25

#eno2 is used for VM addresses. It should be assigned 192.168.3.26 automatically by dhcp
