Is this a production environment or your home lab? There are two ways to setup octavia mgmt network. 

For development I mostly go with tenant type and for production like multi node I will pick a VLAN based network type. 

In your case make sure you have vlan.2140 interface on all controller nodes with IP and on compute nodes you don't need to create that interface because OVS will take that on the provider bridge.

Thanks Eugen, for the prompt response.

config_drive is set to True in amphora VM.

I tried to reach amphora VM from my controller node, but its not reachable.

I found some old articles where they manually created a port on the OVS bridge for lbaas. ( https://cloudbase.it/openstack-on-arm64-lbaas/ ) . 

Is it still recommended ? if it is, should it be on both controller and compute ?

Hi,

can you verify if your amphorae instance has config_drive enabled?

control01:~ # openstack loadbalancer amphora list --long

gives you the list including "compute_id" which is the nova instance, 
then check:

control01:~ # openstack server show <UUID> | grep config_drive
| config_drive                        | True

Usually, with external (provider) networks the instances require the 
config-drive to get their network configuration.
You could also use a customized image for the amphorae to be able to 
login and inspect errors, that's how we usually do it.

Eugen
