Hello Andrew, Searching further, I find "neutron-ovs-cleanup" mentioned in the admin guide:
http://docs.openstack.org/admin-guide-cloud/content/install_neutron-l3.html which says: "If you reboot a node that runs the L3 agent, you must run the neutron-ovs-cleanup command before the neutron-l3-agent service starts." So I believe this service should start during server bootup of network node (where neutron-l3-agent service runs). Maybe they failed to include this in the official admin guide.
