# 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 1. **Parse user's request** to identify: - Network devices (routers, switches, PCs, Cloud, etc.) - Connections between devices - Optional: text labels, area boxes 2. **Generate UUIDs** for each device using a valid UUID v4 format 3. **Calculate layout coordinates** for devices using auto-layout algorithm 4. **Build the .topo XML** following the format in `references/topo-reference.md` 5. **Write the file** to current directory using Write tool 6. **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` ## Device types supported ### Routers | Model | Description | Interface Config | |-------|-------------|------------------| | AR201 | Router | Ethernet x8 + Ethernet x1 | | AR1220 | Router | 2GE + 8Ethernet | | AR2220 | Router | GE x1 + GE x2 + Serial x2 | | AR2240 | Router | GE x1 + GE x2 | | AR3260 | Router | GE x1 + GE x2 | | Router | Generic Router | Ethernet x2 + GE x4 + Serial x4 | | NE40E | Enterprise Router | 10x Ethernet (slot format) | | NE5000E | Core Router | 10x Ethernet (slot format) | | NE9000 | Core Router | 10x Ethernet (slot format) | | R250D | Router | GE x1 | ### Switches | Model | Description | Interface Config | |-------|-------------|------------------| | S3700 | Switch | Ethernet x22 + GE x2 | | S5700 | Switch | 24GE | | CE6800 | Data Center Switch | 20x GE (slot format) | | CE12800 | Data Center Switch | 10x GE (slot format) | | CX | Switch | 10x Ethernet (slot format) | ### Firewalls | Model | Description | Interface Config | |-------|-------------|------------------| | USG5500 | Firewall | GE x9 | | USG6000V | Firewall | GE x1 (slot0) + GE x7 (slot1) | ### Wireless | Model | Description | Interface Config | |-------|-------------|------------------| | AC6005 | Wireless AC | 8GE | | AC6605 | Wireless AC | 24GE | | AP2050 | Wireless AP | 5GE | | AP3030 | Wireless AP | 1GE | | AP4030 | Wireless AP | 2GE | | AP4050 | Wireless AP | 2GE | | AP5030 | Wireless AP | 2GE | | AP6050 | Wireless AP | 2GE | | AP7030 | Wireless AP | 2GE | | AP7050 | Wireless AP | 2GE | | AP8030 | Wireless AP | 3GE | | AP8130 | Wireless AP | 3GE | | AP9131 | Wireless AP | 2GE | | AD9430 | LTE Module | 28GE | | STA | Wireless Station | Wireless | | Cellphone | Mobile Device | Wireless | ### Endpoints | Model | Description | Interface Config | |-------|-------------|------------------| | PC | PC | 1GE | | Laptop | Laptop | 1GE | | Server | Server | 1Ethernet | | Client | Client | 1Ethernet | | MCS | Multicast Server | 1Ethernet | | Cloud | Cloud/BNI | Ethernet interfaces | | FRSW | Frame Relay Switch | Serial x16 | | HUB | Ethernet HUB | Ethernet x16 | ## Connection types | Type | Description | |------|-------------| | Copper | Ethernet cable | | Serial | Serial cable | | Auto | Auto-detect | ## 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 `.topo` extension ## Opening the result After writing the file, print the absolute path: ``` 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
