I ran ovs-vsctl show
Here is the output for br-ex:

It's connected to the enp0s3 interface (Centos 7's interface), the br-ex interface, and to the virtual router.

About the output of ovs:
I'm not sure what you mean exactly.  If I ping from the virtual router namespace, I can reach (host os) and (guest os).    
tcpdump shows that the enp0S3 port detects the ping.The br-ex port detects the ping.

 What's the config on your external bridge and the output of your ovs?

 When I ping from my root namespace, there is a reply.     Pinging gets no reply.   Also, my physical router is reachable at, because I configure it via browser with that local IP.
Thanks for your reply, Remo!

 Maybe your gateway is .2 and not .1 did you try that. If that's the case you need to change that in your openstack config so you can get out

   I have RDO ALL-In-One installed.    I set up a private network and a public (external) network.     I set up a virtual router to connect the private network to the external network.    I have RDO installed on Centos 7 as a guest.  Windows 10 is my host OS.
When I move into the virtual router's namespace, I can ping the guest os's IP address ( and I can ping the host os's address (, but when I try to ping the gateway ( it tells me it is unreachable.  It also fails when I try to ping google.com
  I can ping the gateway and google.com from the root namespace of the guest os, centos 7.

   RDO uses Open vSwitch.
 I'd appreciate any help on this problem!
  Thanks!  ...John
