Answer
eBPF enables direct routing, load balancing, and policy enforcement without iptables.
Quick Answer
Cilium attaches eBPF programs to network interfaces and socket layers. When a Pod connects to a Service ClusterIP, Cilium's eBPF socket-level program intercepts the connect() syscall and redirects it directly to a backend Pod's IP — without going through the kernel network stack, without iptables, and without needing kube-proxy at all. L7 policies work similarly.
