the network in my exercise I am learning about networks and I just started to learn about dynamic routing(like RIP) but there is something I didn't managed to understand and is why do I need in the "network" command to give the network name of the connection between the routers(16.0.0.0) in order to have network 15.0.0.0 to communicate with network 192.168.0.0 ?.
from what I understood all what you do here is to advertise other networks connected to the router to other connected routers. so why couldn't I just write "network 15.0.0.0" and "network 192.168.0.0" to make the routers know about each other's connected networks?.
