Network Config Generator

Explore network device configuration templating with Jinja2. Edit template variables and see the rendered configuration in real-time.

How It Works

Select a supported template (standards-config or aaa-config)
Fill in the context variables
Submit to the Flask API (POST /api/render-config)
View the rendered configuration in the output panel

This demo showcases: - Jinja2 Templating – Industry-standard template engine for configuration management - Variable Substitution – Dynamic config generation based on inputs - Network Automation – Practical example of IaC (Infrastructure as Code)

Supported Templates

Standards Enforcement (standards-config)
- NTP, DNS, SNMP, syslog, and management interface settings.
AAA Configuration (aaa-config)
- RADIUS server definitions, AAA group policies, authentication/authorization/accounting, and SSH access controls.
