Nautobot IGP Models

Nautobot IGP Models

An App for Nautobot.

Overview

The Nautobot IGP Models app extends Nautobot to provide comprehensive modeling and management of Interior Gateway Protocol (IGP) routing configurations. This app enables network engineers and automation teams to maintain a source of truth for ISIS and OSPF routing instances, process configurations, and interface-level routing parameters across their network infrastructure.

With this app, you can model complete IGP topologies including routing instances per device, protocol-specific configurations (ISIS NET generation, OSPF process IDs), and granular interface settings (ISIS circuit types and metrics, OSPF areas and costs). The app provides full CRUD operations via both the Nautobot web UI and REST API, making it ideal for both manual network documentation and programmatic network automation workflows. Whether you're documenting existing IGP deployments, planning network migrations, or generating router configurations from structured data, the IGP Models app provides the data foundation you need.

The app integrates seamlessly with Nautobot's existing device and interface models, supports custom fields and relationships for extensibility, and includes comprehensive filtering and bulk editing capabilities. It also features intelligent defaults like automatic ISIS NET generation from router IDs and configurable status tracking for lifecycle management.

Key Features

• Multiple IGP Protocol Support: Model both ISIS and OSPF configurations on the same or different devices
• Hierarchical Configuration: Organize routing configs from device-level instances down to interface-specific parameters
• ISIS NET Auto-Generation: Automatically generate valid ISIS Network Entity Titles (NETs) from router IDs and area identifiers
• Comprehensive Interface Configuration: Track circuit types, metrics, areas, and costs at the interface level
• Full API Access: Complete REST API for programmatic access and automation integration
• Status Lifecycle Management: Track configuration states (Planned, Active, Decommissioned)
• Extensibility: Leverage Nautobot's custom fields, relationships, and webhooks
• Demo Data: Includes management command to load realistic network topology for testing

Supported Use Cases

• Network documentation and source of truth for IGP routing configurations
• Configuration generation for network automation tools (Ansible, Nornir, etc.)
• Migration planning between routing protocols (ISIS to OSPF, vice versa)
• Validation of routing design consistency across the network
• Integration with monitoring systems for configuration drift detection

More details can be found in the Using the App documentation.

Try it out!

This app can be tested in your local development environment using the included demo data:

# Start development environment
invoke build && invoke start

# Load demo data
invoke nbshell
# In the shell:
from nautobot_igp_models.management.commands.load_igp_demo_data import Command
Command().handle()
exit()

# Access Nautobot at http://localhost:8080
# Navigate to: Routing → IGP - Link-State

The demo data creates a realistic 4-router network topology with ISIS and OSPF configurations for exploration and testing.
