centos6.3的桥接网卡配置失败，请教高手

我的两个配置文件如下：
cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
#BOOTPROTO="none"
BROADCAST="192.168.1.255"
IPADDR="192.168.1.19"
NETMASK="255.255.255.0"
NETWORK="192.168.1.0"
GATWAY="192.168.1.1"
HWADDR="48:5B:39:E9:78:E9"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
BRIDGE="br0"
UUID="0e69b837-e8de-4997-a3e1-59c9808b51e8"

cat /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE="br0"
BOOTPROTO="static"
PREFIX=24
IPADDR="192.168.2.21"
NETMASK="255.255.255.0"
GATWAY="192.168.2.1"
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Bridge"
STP="on"
DELAY="0"
#UUID="0e69b837-e8de-4997-a3e1-59c9808b51e8"

但是，在运行service network restart 后  ifcfg-br0加载失败，请问应该如何修改配置文件

eth0不用设置IP和MAC的！
你这样改试一下吧！
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
MASTER=bond0
slave=yes
USERCTL=no

lockstream

修改后还是无效，问题是在ifcfg-br0的配置上
