The Avi Load Balancer SE management interface must be connected to a logical segment. The management-logical segment needs connectivity to be able to reach the Avi Load Balancer controller management IP. It is recommended to have a dedicated tier-1 gateway and segment for Avi Load Balancer SE management for NSX-T Overlay Transport Zone/Segments deployments, providing no bottlenecks for the managment network connectivity between Avi Load Balancer Controller and Service Engines.
For the NSX-T Overlay Transport Zone/Segments deployment, before creating the NSX-T cloud in the Avi Load Balancer Controller, create the following SE dedicated management Tier-1 gateway and a management segment in NSX-T manager:
