BGP Peering Patterns for Kubernetes Networking at Preferred Networks

Learn advanced BGP peering patterns for Kubernetes networking through real-world experience from Preferred Networks in this 30-minute conference talk. Discover how Border Gateway Protocol is increasingly used to connect Kubernetes networking with existing IT infrastructure, particularly in large-scale and on-premises environments. Explore two key BGP peering patterns that enhance Kubernetes networking while maintaining operational simplicity: the Sidecar BGP Peering Pattern, which involves running a dedicated BGP speaker alongside Kubernetes networking components to balance automation with fine-grained control, and Native Routing over IP Clos Networks, a tunneling-free approach that integrates Kubernetes with large-scale BGP-based datacenter fabrics for improved performance. Gain insights into best practices and lessons learned from actual deployment scenarios to help design scalable and reliable Kubernetes networking solutions using BGP, addressing the complexity of modern network architectures that require greater flexibility and control over BGP deployment strategies.
