restart control node (network node) the vxlan mode neutronservice will cause ovs ha qr qg routers and other equipment for the tag device 4095 cause the tag can not communicate on the
Now Problem Solution
-
Modify database information
4095 port neutron.ml2_port_bindingsstatus table must bebind_failed
update neutron.ml2_port_bindings set vif_type='ubound' where port_id like {PORTID}
-
Restart
openvswitchneutron-openvswitch-agentsolve
The problem is that the community openstack 4095 bug, the community has been discussed in detail, the fundamental reason is that neutron-server service than neutron-openvswitch-agent due to start soon
1. The server is down, the service on this server is marked as neutron down state
2. After the server is powered on, neutron server service first started, check the agent found the service did not start, the ports are labeled bind failed state.
3. agent after the start, we found that these ports are down state. . . Then put them into a 4095 marker. . .

P version of this issue has been resolved, but the code changes more, we do not deserve to spend too much energy to backport come back, we still have to test to solve it by managing the service startup sequence.
