Hi,

We did test Octavia with Pike (DVR deployment) and everything was 
working right our of the box. We changed our underlay network to a 
Layer3 spine-leaf network now and did not deploy DVR as we don't wanted 
to have that much cables in a rack.

Octavia is not working right now as the lb-mgmt-net does not exist on 
the compute nodes nor does a br-ex.

The control nodes running

octavia_worker
octavia_housekeeping
octavia_health_manager
octavia_api

and as far as I understood octavia_worker, octavia_housekeeping and 
octavia_health_manager have to talk to the amphora instances. But the 
control nodes are spread over three different leafs. So each control 
node in a different L2 domain.

So the question is how to deploy a lb-mgmt-net network in our setup?

- Compute nodes have no "stretched" L2 domain
- Control nodes, compute nodes and network nodes are in L3 networks like 
api, storage, ...
- Only network nodes are connected to a L2 domain (with a separated NIC) 
providing the "public" network


All the best,
Florian
