eNSP Topology Skill\r

\r Generate eNSP (Enterprise Network Simulation Platform) topology files as native .topo files that can be opened directly in eNSP.\r \r

How to create a topology\r

\r

1. Parse user's request to identify:\r
   • Network devices (routers, switches, PCs, Cloud, etc.)\r
   • Connections between devices\r
   • Optional: text labels, area boxes\r \r
2. Generate UUIDs for each device using a valid UUID v4 format\r \r
3. Calculate layout coordinates for devices using auto-layout algorithm\r \r
4. Build the .topo XML following the format in references/topo-reference.md\r \r
5. Write the file to current directory using Write tool\r \r
6. Open the result - print the file path so user can open it in eNSP\r \r

Output format\r

\r Always output a .topo file. The user will open it in eNSP for simulation.\r \r Example filenames:\r

• simple-network.topo\r
• ospf-topology.topo\r
• campus-network.topo\r \r

Layout algorithm\r

\r Use a simple grid-based auto-layout:\r \r

Grid spacing: 200px horizontal, 150px vertical\r
Device size: ~80x60px\r
Start position: (100, 100)\r
\r
For each row:\r
  - Place devices horizontally with 200px gap\r
  - Move to next row when reaching canvas width (~1200px)\r
```\r
\r
Adjust positions based on device types and connections to create logical groupings.\r
\r
## Adding text labels (txttips)\r
\r
Common labels for network diagrams:\r
- Loopback addresses: `Loopback0:10.0.1.1/24`\r
- Network segments: `10.0.12.0/24`\r
- Area labels: `Area0`, `Area1`, `AS 64512`\r
- Device roles: `Core Layer`, `Access Layer`\r
\r
## Adding area boxes (shapes)\r
\r
Use type="1" shapes with appropriate colors to group devices:\r
- Same area devices in one rectangle\r
- Different colors for different areas/zones\r
\r
## File naming\r
\r
- Use lowercase with hyphens\r
- Descriptive name based on topology purpose\r
- End with `.topo` extension\r
\r
## Opening the result\r
\r
After writing the file, print the absolute path:\r
```\r
Topology saved to: C:\path	o	opology.topo\r
Please open this file in eNSP to view and simulate.\r
```\r
\r
## XML format reference\r
\r
Consult `references/topo-reference.md` for complete XML structure including:\r
- Device XML format with slots and interfaces\r
- Line XML format with interfacePair details\r
- Shape XML format for area boxes\r
- Txttip XML format for text annotations\r
