Brian Linkletter modernized the FRR01 lab in the srl-labs/containerlab repository, focusing on maintainability and compatibility for network lab deployments. He upgraded container images to FRR 10.5.1, migrated the topology to the latest Containerlab syntax, and removed legacy startup scripts, streamlining the deployment process. Using Docker, Linux, and YAML, Brian validated the new setup by ensuring OSPF neighbor formation and host reachability across six containers. His work aligned the lab with platform migrations from Docker Hub to Quay, improved reproducibility, and enhanced onboarding by adopting a declarative, scalable design. The changes addressed ongoing support and reduced maintenance overhead.
