- Containerlab users testing network control planes
- Worth noticing
- A host-level UI discovers agents across running labs, and each node's configuration is saved in its lab folder as clabgen.yml.
Field notes
Each agent runs as a clab node and takes over its data interfaces; a host-level UI discovers agents across running labs, while configuration can also arrive through YAML scenarios, CLI, API, or Python/pytest fixtures. The feature list spans BGP, IS-IS, OSPF, BFD, and Ethernet CFM/Y.1731, including fault injection and delay/loss measurements. Example labs include two agents back-to-back and a Nokia SR-SIM setup that requires its own image and license.
