我有两个网卡,配置如下：

ip路由：
$ip route 192.168.5.0/24 dev eth0 proto kernel scope link src 192.168.5.104 85.255.103.0/24 dev eth1 proto kernel scope link src 85.255.103.4 default via 192.168.5.1 dev eth0 default via 85.255.103.1 dev eth1
当我ping eth1的ip地址时,我得不到任何回复.
使用tcpdump,我认为发送到eth1的所有ICMP回应请求都是通过eth0接口回答的.
如何实现两个接口正常工作？如果我ping eth1,它也应该返回eth1的答案.
eth0有一个更快的互联网连接,我只想保持eth1周围,并在应用程序绑定到特定的IP时通过它.
