Hello /etc/sysconfig/network-scripts/ifcfg-eth0 looks like this: # Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) TYPE=Ethernet NAME=eth0 NM_CONTROLLED=no IPV4_FAILURE_FATAL=yes UUID=cc2635ff-3c14-48ba-b19a-84c5b9d36a9d ONBOOT=yes DEVICE=eth0 BOOTPROTO=none HWADDR=00:50:56:01:00:01 BROADCAST=192.168.0.255 IPADDR=192.168.0.10 NETMASK=255.255.255.0 NETWORK=192.168.0.0

CentOS-6.10 We have a host with the following ifcfg file contents: BOOTPROTO=none BROADCAST="" DEFROUTE=yes DEVICE=eth1 . . .

I recommend to configure the ip directly to the interface. #ifcfg-eth2 [...] IPADDR=192.168.200.1 NETMASK=255.255.255.0 IPADDR2=192.168.201.1 NETMASK2=255.255.255.192 ip addr show dev eth2 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:b0:c5:7c brd ff:ff:ff:ff:ff:ff inet 192.168.200.1/24 brd 192.168.200.255 scope global eth2 inet 192.168.201.1/26 brd 192.168.201.63 sc...
