2 NICs on same subnet

2 NICs on same subnet

Hi All,

I need help!
i'm with a problem and i didn't find a solution nowhere. In fact, i'm confused even how to find this my problem in the forums for example.

Well, i have a equipment with Linux Centos and 2ethernet ports. I enabled 2 ports, eth0 and eth1, and configured them with static ips (eth0 = 192.168.31.5 and eth1 = 192.168.31.9). Ok!

If i plug 2 ethernet cables, one for each, i can to ping my equipment by 2 ips, 192.168.31.5 and 192.168.31.9. But, if i remove the cable from eth1, i still can to ping in these 2 ips. After of this i can to disable the eth1 and 2 ips still will be available for me in the eth0 port.

I did a test, and if i configure the 2 ips in distinct subnets this problem doesn't occur.

Right now, if i to plug the cable in eth1 will not do difference, just eth0 port is working.

Someone know about this? Sorry,but my english is not so good...

Thanks!
