Hello F5_Design_Engineer 

Thanks for sharing the URL. I have checked the URL. As per my understanding example config shown in that URL is for backend servers deployed in Azure Vnet and not in AVS ( Azure VMware Solution) private cloud.  Whether we have any config document about F5 deployment in VS ( Azure VMware Solution) private cloud in layer-3 mode. As per my understanding F5 LB as a Service Insertion with NSX-T is not feasible for AVS since it is controlled Environment by Azure & VMware.
