In my previous post "Step-by-step VMware Cloud Foundation 4.3 design and install MGMT domain" we have completed VCF management domain deployment.
As we are using version 4.3, which gives us flexibility of deploying either with Static routing or dynamic using BGP, it doesn't deploy edge nodes and no AVN gets created. It actually allows us "Architects" to design and deploy without manual intervention or work around for keeping up with the needs of customer.
In a brown field deployment if you have an underlay network which is configured with static routes, as customer have limited subnets and do not have requirement of rapid network provisioning, they would not want to enable BGP, only to accommodate VCF and to design around this requirement we used work arounds, but now its a straight solution.
