The below is the RIP protocol's declaring the routing command:
Router(config)#router rip
Router(config-router)#version 2
Router(config-router)#network 1.1.1.1
Router(config-router)#network 192.168.12.0
Router(config-router)#exit
I want to know why the RIP protocol announcing the network, only wants the network IP address, but not the mask?
no auto-summary
command.
