router rip
Enter RIP process config. Then 'network <classful-net>' enables RIP on matching interfaces.
RIP here always behaves like version 2 with 'no auto-summary': routes carry their exact prefix and are never summarised at a classful boundary. 'version 2' and 'no auto-summary' are still shown in running-config, but they change nothing.
Don't just read it — type router rip in a real network simulator in your browser and watch it take effect. No install, no account needed to start.
