If you are using gre mode. you have to create br-tun and restart your neutron-ovs agent. If you are using vlan you have to create all bridges mentioned in bridge_mappings inside '/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini' You can not expect your floating ip to work untill you can ping the external router from your instance(using vnc window) Thank you, Ageeleshwar K http://www.csscorp.com/common/email-disclaimer.php -------------- next part -------------- An HTML attachment was scrubbed...
