<div>Was the interface you added to br-ex the same interface to which you connected to the box? If so, this is expected. When you add an interface to the bridge you lose IP connectivity to that interface. The IP address which which was assigned to the interface
now needs to be assigned to the br-ex bridge, and then you'll have connectivity once again.</div>

<div dir="ltr">Hi Team,<br>
<br>
While adding external bridge connection lost to the network node from other nodes. we couldn't ssh to network node after creating bridge.<br>
<br>
<pre>If we do below steps of following link
<a href="http://docs.openstack.org/icehouse/install-guide/install/apt/content/neutron-ml2-network-node.html" target="_blank">http://docs.openstack.org/icehouse/install-guide/install/apt/content/neutron-ml2-network-node.html</a>
===========================================
3) Add the external bridge:
# ovs-vsctl add-br br-ex
4) Add a port to the external bridge that connects to the physical
external network interface:
Replace INTERFACE_NAME with the actual interface name. For example, eth2
or ens256.
# ovs-vsctl add-port br-ex INTERFACE_NAME
=============================================
External connection to network node fails. Then we couldn't connect to network node from other machines.
