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.topo
ospf-topology.topo
campus-network.topo

Layout algorithm

Use a simple grid-based auto-layout:

text

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 .topo extension

Opening the result

After writing the file, print the absolute path:

text

Topology saved to: C:\path\to\topology.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
