The Swiss Army Knife of Cloud Native Networking
summary
Cilium runs eBPF to replace iptables/ipvs and now ships BGP control plane v2 in the upcoming 1.16 (July) to advertise Service and LoadBalancer IPs, with graceful restart and MD5 sessions. Demo uses a kind cluster of four nodes in a two‑rack model, three tenant namespaces (blue/red/yellow), IP pools (per-tenant CIDRs) and shows nodes establishing BGP peers and external routers learning prefixes; fallback is layer‑2 announcement for simpler labs. Also demonstrates LB IPAM and Gateway API’s infrastructure field for propagating cloud labels.
