I have centos 64 6.5
I installed bridge-utils I installed tunctl
I added BRIDGE=br0 to ifcfg-eth0 I created ifcfg-br0 with correct settings
I did service network restart and I get an error about br0 not present.
When I plug in the second network (USB to ethernet) It detects as eth1
What do I need to change to get this to work.
Thanks,
jerry

What is your complete network configuration?

Iirc, there is/was a bug where the bridge's file name had to sort *after* the slaved interfaces. 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="8.8.8.8" DNS2="8.8.4.4" 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.

[ I'm happy I didn't get bitten by any bug like that! ]
Maybe there _was_ a bug.
I have interfaces that start with a "c" and that alphabetically comes before "ethX" or "pXpY". I haven't seen any problems with this configuration.
I don't have an IP address (and gateway+dns info) on my bridges.
*after* the slaved interfaces. So I always use 'vbrX' instead of 'brX
This "bug" you speak of may be entirely related to your Ethernet bonding though and not the bridging aspect.

Thanks for sharing configs. It's always helpful to see how others are configuring their systems.
