<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Which version of OpenStack? If the router is plugged into br-ex and not br-int you may see this condition. Often, an external bridge like br-ex is not properly configured, leading
to issues. You might try creating a provider bridge using the ovs-vsctl tool, defining the mapping in the plugin configuration file, and using router-gateway-set to associate the router with that network.
<div><br>
</div>
<div>It would help to see your 'ovs-vsctl show' output along with the plugin configuration file and a 'neutron net-show <netid>' of the external network.</div>

<div dir="ltr">hi,
<div>VM works fine and can ping each other within the same project .</div>
<div>But VM can not ping gateway , not able to ping router external interface from external .<br>
<div><br>
</div>
<div>here is the port-show and noticed ports are down .</div>
<div>any idea ? thanks !</div>
