br-ex not being assigned IP address automatically at boot
OpenStack Juno installed as per RDO onto a CentOS 7.0 Host. (NetworkManager disabled, network service enabled.)
Interface br-ex is not assigned any address (automatically) at boot of OpenStack host:
[root@CentOS7Host02 ~]# ifconfig br-ex
br-ex: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::847e:5dff:feae:814c prefixlen 64 scopeid 0x20<link>
ether 86:7e:5d:ae:81:4c txqueuelen 0 (Ethernet)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 10 bytes 828 (828.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Here is its configuration:
[root@CentOS7Host02 ~]# cat /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=172.24.4.225_br_ex
NETMASK=255.255.255.240_br_ex
ONBOOT=yes
Should this not be assigning the address 172.24.4.225 automatically at boot?
Note that if I manually configure the address (i.e. via ifconfig from the command line) then all works well.
