summary
Case study shows a working solution to give tenant pods private interfaces in a shared AKS cluster using KEP-3698 multi-network, a custom PodNetwork CRD plus a CNI extension and a device plugin that registers extra NICs to the kube-scheduler. Demo provisions pods with two IPs (infra + tenant), supports fixed IPs per pod, and proves isolation: Red pod cannot reach Blue pod and tenant VMs reach only their pod. Azure VM SKU limits apply (currently up to eight NICs).
