LBaaS (octavia) on Openstack 12 (Pike)

Hello folks,

We need your help with our openstack environment.
It is our first openstack environment and we are not experts. We had some experts here to bring it up and running. Currently we are getting stuck to implement LBaaS.
We are learning day by day more but I hope to get some support from the community here.
I appreciate it very much.

the environment is as follows:

openstack v12
1 Director
2 Compute nodes
3 Controller nodes

I have installed LBaaS using the instruction below
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html-single/networking_guide/index#configure_lbaas

Current status. LBaaS is running
Neutron commands are not available and openstack cli should be instead.
Unfortunately I cannot find the corresponding commands.

second issue
LB is not visible on the Horizon dashboard
I edit /etc/openstack-dashboard/local_settings adding "enable_lb" entry
OPENSTACK_NEUTRON_NETWORK = {
'enable_router': True,
'enable_quotas': True,
'enable_ipv6': True,
'enable_distributed_router': False,
'enable_ha_router': False,
'enable_fip_topology_check': True,
'enable_firewall': True,
'enable_lb': True,

Thank you very much
Best Regards

Niko
