Open Stack

Hi Laurent,
Thank you very much for your reply.we configured our network as per
official document .Please take a look at below details.
--->Controller node configured with below interfaces
bond1,bond0,br-mgmt,br-vxlan,br-storage,br-vlan

---> Compute node
bond1,bond0,br-mgmt,br-vxlan,br-storage

I don't have much more experience in openstack,I think here we used vlan
network.

Thanks & Regards
