When you use ClusterIP, the BIG-IP needs to be able to deliver traffic to that IP space. If you use Calico (BGP), that traffic is routed. If you use Flannel (VXLAN), that traffic is sent inside the VXLAN tunnel.
With BGP, the route table will have the next-hop set to the k8s nodes. Traffic is routed to k8s nodes and those nodes further route traffic to the NGINX IC pods.
With VXLAN, the BIG-IP establishes a tunnel with the k8s nodes at the other end. Traffic is sent inside the tunnel and arrives at the k8s nodes, and traffic is taken out from the tunnel and delivered to the NGINX IC pods.
