Configuration Templates 🎯 Apply complex configurations with simple parameters: ```python # Before (v1.0): Manual commands commands = [ "router ospf 1", "router-id 1.1.1.1", "network 192.168.1.0 0.0.0.255 area 0", "exit" ] # After (v2.0): Simple template gns3_apply_config_template( template_name="ospf", template_params={ "process_id": 1, "router_id": "1.1.1.1", "networks": [{"network": "192.168.1.0", "wildcard": "0.0.0.255", "area": 0}] } ) ``` ### 2. Bulk Operations ⚡ Configure multiple devices at once: ```python gns3_bulk_configure_nodes([ {"node_id": "r1", "commands": [...], "save_config": True}, {"node_id": "r2", "commands": [...], "save_config": True}, {"node_id": "r3", "commands": [...], "save_config": True} ]) ``` ### 3. Topology Validation ✅ Automated network health checks: ```python result = gns3_validate_topology(project_id) # Checks: disconnected nodes, stopped devices, overlaps, issues ``` ### 4. Complete Snapshot Control 📸 Full version control: ```python gns3_create_snapshot(project_id, "Before_Changes") gns3_list_snapshots(project_id) gns3_restore_snapshot(project_id, snapshot_id) ``` ### 5. Enhanced Console Access 💻 Auto-detection and config mode support: ```python gns3_send_console_commands( commands=["interface g0/0", "ip address 10.1.1.1 255.255.255.0"], enter_config_mode=True, # Automatic! save_config=True # Automatic! ) ``` ### 6. Drawing & Annotation ✏️ Document your topologies: ```python gns3_add_text_annotation(text="Core Network", x=0, y=-50) gns3_add_shape(shape_type="rectangle", x=0, y=0, width=200, height=100) ``` --- ## 🎓 Common Scenarios ### Scenario 1: Build CCNA Practice Lab ``` 1. "Create a new project called CCNA_Lab" 2. "Add 2 routers named R1 and R2" 3. "Add 2 switches named SW1 and SW2" 4. "Add 4 PCs" 5. "Connect R1 to R2, R1 to SW1, R2 to SW2" 6. "Configure OSPF between R1 and R2" 7. "Configure DHCP on both routers" 8. "Create snapshot called Clean_State" ``` ### Scenario 2: Configure VLANs ``` 1. "Create VLANs 10, 20, 30 on SW1" 2. "Configure port g0/1 as trunk" 3. "Configure port f0/1 in VLAN 10" 4. "Configure port f0/2 in VLAN 20" 5. "Save the configuration" ``` ### Scenario 3: Troubleshoot Network ``` 1. "Validate my network topology" 2. "Show running config on R1" 3. "Send 'show ip route' to R1" 4. "Start packet capture between R1 and R2" 5. "Stop all nodes and restart them" ``` ### Scenario 4: Bulk SSH Configuration ``` 1. "Configure SSH on all routers with username admin, password cisco123" ``` --- ## 📈 Performance & Statistics ### Code Metrics - **Total Python Files:** 23 files - **Total Lines of Code:** ~4,000+ lines - **Core Modules:** 2,319 lines (server.py + modules) - **Documentation:** 2,063 lines - **Examples:** 400+ lines ### Feature Comparison | Metric | v1.0 | v2.0 | Improvement | |--------|------|------|-------------| | Tools | 12 | 42 | +350% | | Templates | 0 | 15+ | New Feature | | Modules | 1 | 4 | Modular | | Docs | 1 | 6 | +600% | | Features | Basic | Complete | Production | --- ## ✨ Backward Compatibility ### Your Gemini Integration Still Works! ✅ Same `run.bat` launcher ✅ Same `mcp-server.json` config ✅ Same environment variables ✅ No changes needed to Gemini setup ### Old Scripts Backed Up - `server_old.py` - Your v1.0 backup - Can rollback if needed - Migration guide available --- ## 🎯 What Can You Do Now? ### ✅ Complete Network Automation - Build any topology from scratch - Configure routing (OSPF, EIGRP, BGP) - Set up switching (VLANs, trunks) - Configure services (DHCP, NAT) - Implement security (ACLs, SSH) - Manage lifecycle (snapshots, validation) ### ✅ Enterprise-Ready Features - Bulk device configuration - Topology validation - Version control (snapshots) - Traffic capture - Documentation (drawings) - Complete API coverage ### ✅ AI-Powered Workflows - Natural language commands - Intelligent configuration - Automated validation - Smart troubleshooting --- ## 🆘 Need Help? ### Documentation - **[TOOL_REFERENCE.md](TOOL_REFERENCE.md)** - All 42 tools documented - **[README.md](README.md)** - Complete project overview - **[MIGRATION.md](MIGRATION.md)** - If upgrading from v1.0 ### Examples - **[example_complete_network.py](example_complete_network.py)** - Comprehensive demo - Test scripts in project root ### Common Issues 1. **GNS3 not running:** Start GNS3 server on http://localhost:3080 2. **Template not found:** Use `gns3_list_templates()` to see available templates 3. **Console timeout:** Increase `boot_timeout` parameter 4. **Connection error:** Check GNS3 server URL and firewall --- ## 🎉 You're All Set!
