Thoughts on networking, automation, and IT
BGP between a Kubernetes eBPF CNI (commonly Cilium) and Cisco/ISP routers can fail in ways that look identical at first glance: sessions flap, prefixes appear and disappear, and traffic blackholes despite “Established” n
Read More →Advanced **kubernetes** pod-to-pod failures in modern datacenters often span multiple layers: CNI dataplane (iptables/eBPF), node routing, VXLAN VTEPs, and BGP EVPN control-plane in the fabric. The fastest path to resolu
Read More →This tutorial walks through an advanced, production-oriented approach to provisioning BGP consistently across multi-vendor ISP networks using **netbox** as the source of truth and Ansible as the automation engine. The go
Read More →ISP datacenters tend to outgrow “default” NetBox assumptions quickly: multi-tenant services, many concurrent peering contexts, repeated patterns across fabrics, and a need to generate config safely and idempotently. This
Read More →Rolling BGP changes on IOS‑XR look easy until you hit the real constraints: long commit times, route-policy blast radius, BFD interactions, RPKI state, multi-vendor edges, and the fact that “one wrong neighbor change” ca
