Hi,

I am trying to set up the bridge, however when the system restart, I can see my physical interface takes the same IP as the bridge. If I bring down/ up using ifdown/ ifup the IP dissapears.

Why and How the physical interface is taking an IP on boot? Below is my configuration

vi /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=OVSPort NAME=ens33 DEVICE=ens33 DEVICETYPE=ovs OVS_BRIDGE=br-ex ONBOOT=yes

vi /etc/sysconfig/network-scripts/ifcfg-br-ex DEVICE=br-ex DEVICETYPE=ovs TYPE=OVSBridge BOOTPROTO=static IPADDR=192.168.187.128 NETMASK=255.255.255.0 GATEWAY=192.168.187.2 IPV4_FAILURE_FATAL=no IPV6INIT=no ONBOOT=yes

Perhaps you will be more successful if you name the interface file ifcfg-ens33. The file name shouldn't really matter, but perhaps it does after all, and it doesn't hurt trying. And after all, it's better to name your objects in a consistent way.

You can also use ovs-vsctl show to check if the interface is really inserted into the bridge.
