Both eth0 and eth1 with the same ip?
Hello!
Just for fun I set to eth0 and eth1 the same IP. Wondering that it works! How is it possible? As i know, it is prohibited to use some IP twise in IPv4 subnet.
My output:
Code:

NETMASK="255.255.255.0"
ONBOOT="yes"
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
