eve-lab-topology-validation

Run the decision gate first to confirm the node list, link list, redundancy level, image availability, and host capacity are all finalized. Then apply the structural, adjacency, resilience, and protocol checklists, stating PASS, WARN, or FAIL for each area.

A thorough topology QA covers structural checks like orphan nodes and connected graphs, role and adjacency rules such as spine-to-leaf-only links, resilience checks for articulation points and redundancy symmetry, and protocol checks for routing coverage and black holes.

The required output has nine sections: requirement summary, best-practice recommendations, image and platform recommendations, physical topology, logical/protocol topology, design validation check, build plan, configuration plan if requested, and risks with open questions.

Build work must not be approved while any decision-gate items remain unresolved, such as unconfirmed scope, missing image availability, or unchecked host resource fit. Unresolved items go into the final risks and open-questions section rather than being silently skipped.

The build plan follows thirteen ordered steps: verify the lab, confirm images, check host capacity, create and verify nodes, map interfaces, create network objects, connect interfaces, verify topology, run the UNL validator, start nodes, apply startup configs, and verify connectivity.
