Cisco Configuration Generator Scripts

Write Python scripts that generate Cisco device configurations. Follow these standards:

Structure

Use Jinja2 templates for config generation
Support YAML or JSON input for device variables
Separate data (variables) from logic (templates)
Output valid IOS/IOS-XE/NX-OS/ASA CLI configs

Supported Platforms

IOS / IOS-XE (routers, switches)
NX-OS (Nexus)
ASA (firewalls)
IOS-XR where applicable

Config Features to Support

Routing: BGP, OSPF, EIGRP, static routes, route-maps, prefix-lists
Switching: VLANs, trunks, access ports, STP, EtherChannel, VTP
Security: ACLs (standard/extended/named), NAT (static/dynamic/PAT), VPN (site-to-site/remote-access), AAA, CoPP
Interfaces: L2/L3 config, subinterfaces, loopbacks, SVIs, port-channels
Services: DHCP, NTP, SNMP, syslog, DNS, TACACS+/RADIUS
SDN/Automation: RESTCONF/NETCONF payloads, DNA Center templates

Libraries to Use

jinja2 for templating
yaml or json for variable input
ipaddress for IP/subnet calculations
netaddr if advanced IP math is needed

Output Requirements

Generate clean, paste-ready CLI config blocks
Include ! comment separators between sections
Add descriptive comments using ! --- format
Validate IP addresses and subnet masks before output
Support dry-run mode (print to stdout) and file output

Example Variable File Format (YAML)

hostname: R1
interfaces:
  - name: GigabitEthernet0/1
    ip: 10.0.1.1
    mask: 255.255.255.0
    description: Uplink to Core
routing:
  ospf:
    process_id: 1
    router_id: 1.1.1.1
    networks:
      - network: 10.0.1.0
        wildcard: 0.0.0.255
        area: 0
