Teaches AI agents to deploy, configure, operate, troubleshoot, and develop FRR (Free Range Routing). Covers all routing protocols (BGP, OSPF, IS-IS, RIP, PIM, LDP, BFD, Babel, PBR, OpenFabric, VRRP, EIGRP, NHRP), multiple deployment models (package, container, source), day-two operations, and FRR codebase development.
