I setup a packstack installation between three nodes (compute, network and controller). I need to make some customs setting and after it i have to restart neutron agent locate at network and compute. After some debug i could see all my agent with command

neutron agent-list

There all up and enable but when i look at ovs-vsctl show (on compute or network) there br-tun that was there with local_ip and remote_ip. i thinked that restart openvswitch agent will resolve it but it doesn't

I suppose your custom settings broke something. What did you do? Anything in the logs?

br-tun that was there with local_ip and remote_ip

You mean it was not there, correct?

Check the Neutron log files. br-tun should appear in /var/log/neutron/openvswitch-agent.log.

Hello @Bernd Bausch

Thk for ur response. What i mean is that after my first installation with packstack the br-tun with local_ip and remote_ip was there but now there is a br-tun brigde without that specific port. I already look at openvswitch-agent.log, there are some lines as br-tun has datapath

If i supposed that my config in neutron.conf, ml2.ini and openvswitch-agent.ini are correct, which command should build that correct config for tunneling.

finally i manually create the vxlan port on the tunnel bridgewith this command

 ovs-vsctl add-port br-tun vxlan-c0a80217 -- set interface vxlan-c0a80217 type=vxlan     options:remote_ip=[ip_of_network_node] options:local_ip=[ip_of_this_node] options:in_key=flow options:out_key=flow options:df_default=true
