Leveraging Cilium and SRv6 for Telco Networking

summary
Shows how Cilium with eBPF is extended to enforce network segmentation and provide single-interface Multi‑VRF by learning BGP routes and installing dynamic SRv6 egress policies, letting IPv4 pods reach IPv4 services over an IPv6 SRv6 fabric. Demonstrates an L3 VPN to a physical PE with SRv6-to‑MPLS gateway translation and visible SRv6 encapsulation on packets; achieves ~23 Gbps on a 25G NIC with AF_XDP. Notes IPv6 scale — a /64 outlasts massive container churn (≈58,000 years).
