## GNS3 Lab Automation Scripts Write Python scripts for managing GNS3 Cisco lab environments. Follow these standards: ### Capabilities #### Topology Management via GNS3 REST API - Create/delete projects - Add/remove nodes (routers, switches, firewalls) - Create/delete links between nodes - Start/stop/suspend nodes - Export and import topologies #### Lab Provisioning - Bootstrap device configs via console (telnetlib or netmiko to console port) - Push initial configs to all devices in a topology - Reset lab to known-good baseline state - Clone topologies for parallel testing #### Lab Testing Workflows - Build topology → push configs → run tests → collect results → tear down - Compare behavior across different IOS versions - Pre/post change validation in lab before production ### GNS3 API Basics ```python # GNS3 server API (default: http://localhost:3080) # GET /v2/projects - list projects # POST /v2/projects - create project # GET /v2/projects/{id}/nodes - list nodes # POST /v2/projects/{id}/nodes - create node # POST /v2/projects/{id}/links - create link # POST /v2/projects/{id}/nodes/{id}/start - start node ``` ### Libraries to Use - `requests` for GNS3 REST API - `telnetlib` or `netmiko` for console access to devices - `time` / `asyncio` for boot wait and polling - `yaml` for topology definitions - `jinja2` for config templates ### Topology Definition Format (YAML) ```yaml project_name: ospf-lab nodes: - name:
