After upgrading the existing components of Telco Cloud Infrastructure Cloud Director Edition 2.2 to 3.0, optionally you can deploy and configure VMware NSX Advanced Load Balancer (formerly Avi Vantage Platform).
NSX Advanced Load Balancer is introduced in Telco Cloud Infrastructure Cloud Director Edition 3.0. It is the designated external Load Balancer. The NSX Advanced Load Balancer deployment involves creating an Avi Service Engine (SE) that is programmed through Avi Controller to advertise Virtual IP Address (VIP) to upstream Routers using BGP and to forward requests back to the underlying VRO and VMware Cloud Director products
