Hi James,

Yes, exactly this block of the doc on "6.14. Fixing OVN controllers that fail to register on edge sites".

The point is that the agent need to be with State "UP" and Alive ":-)".

Also, the command need to bring the column "Alive" as below.

openstack network agent list -c "Agent Type" -c State -c Binary -c Alive
+--------------------+-------+-------+---------------------------+
| Agent Type         | Alive | State | Binary                    |
+--------------------+-------+-------+---------------------------+
| Baremetal Node     | :-)   | UP    | ironic-neutron-agent      |
| Open vSwitch agent | :-)   | UP    | neutron-openvswitch-agent |
| L3 agent           | :-)   | UP    | neutron-l3-agent          |
| DHCP agent         | :-)   | UP    | neutron-dhcp-agent        |
| Baremetal Node     | :-)   | UP    | ironic-neutron-agent      |
+--------------------+-------+-------+---------------------------+

Regards,

Conrado
