Cisco Config Generator

Build a minimal Cisco IOS starter config from a hostname, one interface, and an optional default route.

Hostname

Interface name

IP address

Subnet mask

Description (optional)

Default route next-hop (optional)

hostname Router1
interface GigabitEthernet0/0
 ip address 192.168.1.1 255.255.255.0
 no shutdown
exit
end
write memory

Starter template only — placeholders, no real secrets. Review before applying to real gear.

How to read the result

Fills an IOS template: hostname, interface block with IP/mask, optional default route, then end + write memory. Review before pasting into real gear.

Router1 + Gi0/0 192.168.1.1 → hostname, interface, ip route commands

It is a starter template with no passwords. Always review IPs and masks before applying.

No. Never paste real passwords or keys into any web tool; configure those on-device.
