Network Config Validation

This does pre-deployment validation on router and switch configs with pattern matching for dangerous commands (reload, erase, crypto key zeroize), duplicate IPs, overlapping subnets, and stale references to ACLs or route-maps. The hygiene checks flag things like Telnet on VTY lines, default SNMP communities, and missing NTP or logging config. It's designed for Cisco IOS style syntax and works best as a lightweight gate before change windows or automation runs, not as a full parser. The block iteration logic for VTY sections is worth stealing if you're building your own tooling. Treat the output as evidence that still needs a network engineer's review, especially for management plane changes where a misconfigured access-class can lock you out.
