The Swiss Army Knife of Cloud Native Networking - BRKCLD-1012#

Cisco Live US 2025 (San Diego) digest Program Core pick San Diego · 8–12 June 2025

Abstract

Raymond De Jong (Cisco)

  • Why: Hits the PM's Cilium/BGP/IPAM interests directly — BGP from Cilium and LB IPAM for multi-tenant pools are the operational pieces most teams hit in production.
  • What: Cilium's advanced features — BGP, load balancing, LB IPAM, and network policies — for multi-cloud and multi-tenancy networking, including routing/connectivity between Kubernetes clusters and external networks, BGP setup across different topologies, and multi-tenant routing with multiple IP pools for LoadBalancer IP assignment (from abstract only).
  • How: eBPF datapath (Cilium) with a BGP control plane for external reachability, and LB IPAM pools giving platform engineers per-tenant LB IP allocation.
  • Where applicable: General Cilium/Kubernetes environments; mechanisms are open source even though the speaker is Cisco.
