The below is the RIP protocol's declaring the routing command:

Router(config)#router rip 
Router(config-router)#version 2

I want to know why the RIP protocol announcing the network, only wants the network IP address, but not the mask?

  • You should also use the no auto-summary command.

Because the protocol will check which interfaces belong to each subnet, and get the subnet mask from the interface configuration.

Check this documentation, it will help you understand the way it works
