Network bridge doesn't work for CentOS 7

[jeffwji]

I'm trying to create a bridge in CentOS7, first I created the bridge config:

# vi /etc/sysconfig/network-script/ifcfg-br0
DEVICE=br0
TYPE=Bridge
BOOTRPOTO=dhcp
ONBOOT=yes

Then changed em1 to:

# vi /etc/sysconfig/network-script/ifcfg-em1
HWADDR="18:03:73:B2:19:8C"
TYPE="Ethernet"
BOOTPROTO="none"
NAME="em1"
UUID="c2ee1a26-7638-45ed-b368-0387c005a644"
ONBOOT="yes"
BRIDGE=br0

then restart the network, neither "br0" nor "em1" got IP. what I was missing from the above?
