In my previous post Step-by-step VMware Cloud Foundation 4.2.1 install I scrapped the lab we started for VCF 4.2.1 and now is the time we continue it with Lab constructor. It would be an injustice if I do not mention Tom Stephens(VMware)'s name who introduced VLC to me, and made my life easier.
In order to start with it we need to review the pre-requirements. You need a single physical host running ESXi 6.7+ with 12 cores, 128 GB RAM and 800 GB SSD.
Configure vSphere standard switch, create a trunk port group and set the switch MTU to 9000 , in our case we already have the Nested-SDDC switch and nested-Trunk port group configured. Our trunk port group is inheriting security settings from the switch, where its configured to accept forged transmits, promiscuous mode and mac address change. Disable these settings on the switch level and configure on the port group nested-trunk, we are doing this for only VCF lab, once we are done with this we will revert it. I am also powering off the CSR1000v virtual router, until this lab is complete.
