Answer
eBPF replaces iptables for fast packet filtering and direct routing.
Quick Answer
Docker's network sandbox creates a network namespace for each container. eBPF-based CNI plugins like Cilium attach eBPF programs to the veth interfaces at the namespace boundary, intercepting packets as they enter/leave. Cilium can enforce L7 policies (HTTP path filtering), collect observability metrics, and replace iptables entirely.
