connectivity and IP address management is managed by the non-Cilium CNI plugin, but Cilium attaches BPF programs to the network devices created by the non-Cilium plugin to provide L3/L4/L7 network visibility & (IPAM) via ENI. After the initial networking is setup, the Cilium CNI plugin is called to attach BPF programs to the network devices set up by aws-cni to enforce network policies, perform load-balancing, and allocation (IPAM).
