- description
- Always use when user asks to create, generate, or design a network topology diagram for eNSP (Enterprise Network Simulation Platform), or mentions creating eNSP topologies, network simulations with Huawei devices (AR routers, S5700 switches, PC, Cloud, etc.).
eNSP Topology Skill
Generate eNSP (Enterprise Network Simulation Platform) topology files as native .topo files that can be opened directly in eNSP.
How to create a topology
- Parse user's request to identify:
- Network devices (routers, switches, PCs, Cloud, etc.) - Connections between devices - Optional: text labels, area boxes
- Generate UUIDs for each device using a valid UUID v4 format
- Calculate layout coordinates for devices using auto-layout algorithm
- Build the .topo XML following the format in
references/topo-reference.md
- Write the file to current directory using Write tool
- Open the result - print the file path so user can open it in eNSP
Output format
Always output a .topo file. The user will open it in eNSP for simulation.
Example filenames:
simple-network.topoospf-topology.topocampus-network.topo

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