So I always use 'vbrX' instead of 'brX' (virtual bridge). I don't think the actual DEVICE="..." matter, just the file name, but I like to make the match so I just do vbrX for both. Here is an example of my bridges: ==== vim /etc/sysconfig/network-scripts/ifcfg-vbr2 ==== # Internet-Facing Network - Bridge DEVICE="vbr2" TYPE="Bridge" NM_CONTROLLED="no" BOOTPROTO="none" IPADDR="10.255.50.1" NETMASK="255.255.0.0" GATEWAY="10.255.255.254" DNS1="220.127.116.11" DNS2="18.104.22.168" DEFROUTE="yes" ==== Then an example interface (I use bonds, but this could just as easily be a normal ifcfg-ethX) ==== vim /etc/sysconfig/network-scripts/ifcfg-bond2 ==== # Internet-Facing Network - Bond DEVICE="bond2" BRIDGE="vbr2" NM_CONTROLLED="no" BOOTPROTO="none" ONBOOT="yes" BONDING_OPTS="mode=1 miimon=100 use_carrier=1 updelay=120000 downdelay=0 primary=eth2" ==== Note that the IP moves to the bridge. hth -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?
