## 🎯 Key Features Implemented
### 1. Modular Architecture
```python
# Clean separation of concerns
from gns3_client import GNS3APIClient, GNS3Config
from telnet_client import TelnetClient
from config_templates import ConfigTemplates, TopologyTemplates
```
### 2. Configuration Templates System
```python
# Apply complex configs with simple parameters
await gns3_apply_config_template(
node_id="router-id",
template_name="ospf",
template_params={"process_id": 1, "router_id": "1.1.1.1", ...}
)
```
### 3. Enhanced Console Access
```python
# Auto-detection and config mode support
await gns3_send_console_commands(
commands=["hostname R1", ...],
enter_config_mode=True, # Automatic
save_config=True, # Automatic
enable_password="cisco" # If needed
)
```
### 4. Bulk Operations
```python
# Configure multiple devices efficiently
await gns3_bulk_configure_nodes(
configurations=[
{"node_id": "r1-id", "commands": [...], "save_config": True},
{"node_id": "r2-id", "commands": [...], "save_config": True}
]
)
```
### 5. Topology Validation
```python
# Automated health checks
result = await gns3_validate_topology(project_id)
# Returns: issues, warnings, validation status
```
### 6. Snapshot Management
```python
# Complete version control
await gns3_create_snapshot(project_id, "Before_Changes")
# ...make changes...
await gns3_restore_snapshot(project_id, snapshot_id)
```
### 7. Drawing & Annotation
```python
# Document your topologies
await gns3_add_text_annotation(text="Core Network", x=0, y=-50)
await gns3_add_shape(shape_type="rectangle", x=0, y=0, width=200, height=100)
```

## 🚀 How to Use
### Quick Start
```bash
# 1. Ensure GNS3 server is running on http://localhost:3080
# 2. Already configured with Gemini, just use it!
# Example commands:
gemini "Create a new project called Test_Lab"
gemini "Add 2 routers and a switch to my project"
gemini "Configure OSPF on all routers"
gemini "Show me the complete topology"
gemini "Create a backup snapshot"
```
### API Usage (Programmatic)
```python
from server import *
# Create project
result = await gns3_create_project(name="My_Network")
project_id = result["project"]["project_id"]
# Add devices
await gns3_add_node(project_id, "R1", template_id="...")
# Configure with templates
await gns3_apply_config_template(
project_id, node_id, "ospf", {...}
)
# Validate
await gns3_validate_topology(project_id)
```
