Hi Stuart:

Usually, you need to add a bridge to all network nodes,  you can use
"ovs-vsctl add-br  {br-name}" to add a ovs bridge, then you need to add a
physical port  to that bridge by executing "ovs-vsctl  add-port {bridge}
{port}".
another alternatives, you can append the physical port
to neutron_external_interface variable in globals.yml.  in this case, kolla
will create the ovs bridge automatically.
both of them, you need set octavia_network_interface and configure external
switch properly.

if you really don't know how this works, I propose you  use
 "octavia_network_type: tenant"  ref: [0] , in this case, kolla-ansible
will setup the octavia management network for you, you don't need to do
anything.
