Build a three-router OSPF triangle, watch every router flood the same link-state map, see SPF pick the cheapest path by cost, then kill the best link and watch it reconverge automatically.

Build a two-router eBGP lab with containerlab and FRRouting, announce a single prefix, and learn to read NLRI, AS_PATH, NEXT_HOP, and ORIGIN straight out of RFC 4271 — packet capture included.

Erfahre, wie du mit FRRouting BGP im Homelab aufbaust, Routen redistribuiert, Communities nutzt und typische Fehler vermeidest – Schritt‑für‑Schritt-Anleitung.
