[Execution]

# show destination host unreachable.
$ ping -I eth0 192.168.0.101
# no mac address
$ arp -an

[Question]

I run tcpdump -i eth1 and see arp package sent to eth1.!

Is there any methods to let me able to ping eth1?

You can set a static arp entry corresponding to eth1. But I'm not sure I understand your architecture. Are eth0 and eth1 on the same machine ?

  • both interfaces on the same machine, and sometimes can ping in one direction. adding arp entry is useless – QQQ Aug 30 '15 at 10:48
