Hi,
In your screen shot I see the IP is still on eth2 port. When you add the
eth2 to br-ex OVS bridge, you need to move the IP of eth2 to br-ex for the
connectivity to work.

Subject: [Openstack] help openvswitch network configuration problems
Hi Everyone,
I am now configuring openvswitch for openstack cloud. I have a network
node in the cloud and it has 3 network cards. When I did as the Openstack
Install Guidance said to add port eth2, which is the interface that
connects to the internet in dhcp mode, to the external bridge br-ex, the
whole network node become disconnected from the internet.
Here is the network interface file:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
# management interface
auto eth0
iface eth0 inet static
address 10.0.0.21
netmask 255.255.255.0
#gateway 10.0.0.1
# tunnels interface
auto eth1
iface eth1 inet static
address 10.0.1.21
netmask 255.255.255.0
# external network interface
auto eth2
iface eth2 inet dhcp
up ip link set dev $IFACE up
down ip link set dev $IFACE down
After add eth2 to br-ex, ifconfig presents the following configuration:
Note: A lot of drop in bridge.
Openvswitch configuration:

Shows noting
If I remove eth2 from br-ex, then everything goes well.
By the way I use NAT to connect all other node in the cloud to the
internet, but even if I cancel NAT noting changes. And also I have enabled
ipv4 forwarding.
Any suggestion is warmly welcomed! Thank you very much!!
